Description

  The present invention relates to a waveform reading device, a method, a program, and an electronic musical instrument using the device.

In a sound source device that generates a musical sound waveform by waveform reading method, in order to be able to use a larger number of waveform data for a longer time, unused waveform data is stored in a large-capacity auxiliary storage device such as a flash memory or a hard disk ( Some systems employ a system in which only the waveform data to be used is stored in a secondary storage device and transferred to a waveform memory (primary storage device) that can be directly accessed by the sound source device for sound generation.
In other words, waveform data with a storage capacity greater than the storage capacity of the expensive waveform memory (primary storage device) is held in an inexpensive auxiliary storage device (secondary storage device), and it is moved only when necessary to produce sound. It can be said that this is an efficient method in terms of cost.

  As one conventional technique, the following technique is known (for example, the technique described in Patent Document 1). In this technique, the ROM stores one or more waveform data for each tone color. The tone generator LSI (Large Scale Integrated Circuit) refers to the song data of the specified song, identifies the waveform data that is necessary for the pronunciation of the musical tone, and the waveform data that is identified as necessary is Identify the necessary parts further. As a result, only the necessary part of the waveform data necessary for sound generation is read from the ROM, transferred to the RAM, and stored. This provides a musical sound generator that can further reduce the amount of data when waveform data is stored in a work memory for generating a peak value of a musical sound to be generated.

  As another conventional technique, the following technique is known (for example, the technique described in Patent Document 2). In this technique, when the data group to be transferred when the tone generator is activated among the various data stored in the first storage means, the waveform data constituting the data group is transferred. Among them, waveform data of a predetermined tone color is transferred with priority, and the operation of the tone generator is limited according to the transfer status. For example, operation control is performed to reduce the number of musical sounds that can be generated simultaneously. By restricting the operation, the musical tone generator can be used only for the operations that can be performed in the current transfer status, and can be played in a shorter time from the start of transfer (startup) than when waiting for transfer completion. It is something to be made.

  However, in the above-described prior art, it still takes time to move the waveform data from the auxiliary storage device to the waveform memory or the like, which may hinder the performance. Specifically, when a performer chooses a favorite tone from among a large number of tones, the performer feels stress because there is a time when the tone is switched for a certain period of time and is not pronounced. There was a problem.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to drastically reduce the silent time during which sound cannot be generated because a desired waveform does not exist in the waveform memory at the time of timbre switching involving transfer of a plurality of waveforms.

  In one example, the primary storage device, the secondary storage device that stores a plurality of types of waveform data, and each time the waveform selection signal is supplied from the outside, the first mode or the second mode is determined. The waveform data selected by the waveform selection signal is read out from the secondary storage device and the waveform data read out from the secondary storage device is read out from the secondary storage device when it is determined that the first mode is selected. Read out from the secondary storage device the waveform data selected by the waveform selection signal and other waveform data related to the waveform data when it is determined that the normal mode is the second mode. And a timbre setting reading process for storing the waveform data read from the secondary storage device in the primary storage device.

  According to the present invention, at the time of timbre switching accompanied by the transfer of a plurality of waveforms, it is possible to greatly reduce the silent time in which sound generation is impossible because a desired waveform does not exist in the waveform memory.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as “this embodiment”) will be described in detail with reference to the drawings. When a player selects a timbre in an electronic musical instrument, it can be roughly divided into a case in which a timbre predetermined for performance is called and a case in which one of the timbre categories that is most suitable for the music to be played is selected. . In the latter case, for example, when a player wants to select a piano tone suitable for the music to be played most, the performer first selects the tone category of the piano tone, and then selects a plurality of piano tones that are prepared one after another. Often perform operations such as listening and comparing. In other words, when a timbre of a certain number is specified, the timbre number increase button or the timbre number decrease button is continuously pressed against the timbre, and the timbre of the adjacent number is selected one after another. There are many. Therefore, in this embodiment, a total of three waveform areas (waveform area 1, waveform area 2, and waveform area 3) are obtained by adding a waveform area for timbres with numbers before and after that to a waveform area for timbres with a certain number. Is prepared. Each time the performer operates the timbre number increase button or the timbre number decrease button, the specified number and the waveform data before and after the number are stored in three waveform areas, so that adjacent timbre movement can be instantaneously performed. By doing so, an electronic musical instrument that can keep the silent state to a minimum is realized.

  FIG. 1 is an external view of an embodiment of an electronic keyboard instrument according to the present invention. This embodiment is implemented as an electronic keyboard instrument 100. The electronic keyboard instrument 100 includes a keyboard 101 composed of a plurality of keys as performance operators, a tone color selection button 102 for selecting a tone, and a tone number increment button (hereinafter referred to as “Increment”) as a waveform selection operator. : Abbreviation of “increase”)) 106a, a tone number decrease button (hereinafter referred to as “decrement”) 106b, and a registration selection button 103 for selecting various functions other than the tone. And a vendor / modulation wheel 104 for adding various modulations (performance effects) such as pitch bend, tremolo, and vibrato, and an LCD (Liquid Crystal Display) 105 for displaying various setting information other than timbre and timbre. The electronic keyboard instrument 100 includes a speaker that emits a musical tone generated by a performance on a back surface, a side surface, a back surface, or the like, although not particularly illustrated.

As shown in FIG. 1, the tone selection button 102 includes a piano (“Piano” in the figure), an electric piano (“E. piano” in the figure), an organ (“Organ” in the figure), a guitar / bass (in the figure). "Guitar / Bass"), Wind ("Wind" in the figure), string ("String" in the figure), synth ("Synth" in the figure), or percussion ("Percussion" in the figure) A category button group (“Category” in the figure) for selection and a timbre number button group (for example, “Number” in the figure) of 1 to 8 for selecting a timbre number in each category are provided. That is, the performer first selects a timbre category by pressing one of the category buttons, and then specifies a timbre number within the selected category by pressing one of the timbre number buttons. The Inc button 106a is a button for increasing the timbre number by +1 in the currently selected category. The Dec button 106b is a button for decreasing the timbre number by +1 within the currently selected category.

  FIG. 2 is a diagram illustrating a hardware configuration example of the embodiment of the electronic keyboard instrument 100 of FIG. 2, an electronic keyboard instrument 100 is connected to a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, a large capacity flash (Flash) memory 204, and a waveform memory 206. 1 is connected to a switch panel made up of a tone generator LSI (large scale integrated circuit) 205, the keyboard 105 of FIG. 1, and the tone selection button 102, the Inc button 106a, the Dec button 106b, and the registration selection button 103 of FIG. 1. Scanner 207, A / D converter 208 to which the vendor / modulation wheel 104 in FIG. 1 is connected, LCD controller 209 to which the LCD 105 in FIG. 1 is connected, 16-bit (bit) free-running timer counter 212, and MIDI (Mus cal Instrument Digital Interface) receives an input MIDI I / F (interface) 213, having the configuration are respectively connected to the system bus 214. The digital musical sound waveform data output from the tone generator LSI 205 is converted into an analog musical sound waveform signal by the D / A converter 208, amplified by the amplifier 211, and then output from a speaker or an output terminal (not shown).

  The CPU 201 executes the control operation of the electronic keyboard instrument 100 of FIG. 1 by executing the control program stored in the ROM 202 while using the RAM 203 as a work memory. The ROM 202 stores the control program and various fixed data.

  The large-capacity flash memory 204 is a storage area for large-capacity data such as waveform data, and is sequentially accessed by sequential access. On the other hand, the tone generator LSI 205 is connected to a waveform memory 206 composed of a RAM for developing waveform data, and the waveform data of the musical sound to be generated must be arranged on the waveform memory 206 without fail. The CPU 201 can read out the waveform data from the large-capacity flash memory 204 and transfer it to the waveform memory 206 via the tone generator LSI 205, thereby replacing the timbre data.

  The tone generator LSI 205 reads the waveform data from the storage area of the target timbre transferred to the waveform memory 206 at a speed corresponding to the pitch of the key designated by the performance, and designates the read waveform data by the performance. The amplitude envelope of the velocity is added, and the waveform data obtained as a result is output as output musical sound waveform data.

  The LCD controller 209 is an IC (integrated circuit) that controls the LCD 105. The key scanner 207 is an IC that scans the state of the switch panel such as the keyboard 105, the timbre selection button 102, the Inc button 106a, the Dec button 106b, or the registration selection button 103 and notifies the CPU 201 of it. The A / D converter 208 is an IC that detects the operating position of the vendor / modulation wheel 104. The 16-bit free-running timer counter 212 measures time for event time detection.

  FIG. 3 is a diagram showing an example of a timbre arrangement relationship between the waveform memory 206 and the large-capacity flash memory 204 (shown as “Flash memory” in the drawing). As shown in FIG. 3, the large-capacity flash memory 204 has a tone number button group in the tone color selection button 102 in FIG. 1 for each tone category specified by the category button group in the tone color selection button 102 in FIG. Alternatively, waveform data for each timbre number designated by the Inc button 106a or the Dec button 106b in FIG. 1 is stored sequentially. In the example of FIG. 3, the large-capacity flash memory 204 stores waveform data of a Piano 1 waveform, a Piano 2 waveform,..., A Piano 20 waveform with respect to the Piano tone color category. For the Piano timbre category. Piano 1 waveform, E.I. Piano 2 waveform,. An example in which waveform data of a Piano 20 waveform is stored is shown. Within one timbre category, waveform data of up to 20 timbres are sequentially stored in a continuous storage area, and 16 timbre categories are sequentially stored. Accordingly, in the large-capacity flash memory 204, waveform data for a total of 20 × 16 = 320 timbres is sequentially stored in a continuous storage area. On the other hand, the waveform memory 206 is prepared with a total of three waveform areas, waveform area 1, waveform area 2, and waveform area 3. Then, in the case where the performer performs an operation of successively selecting the timbres of adjacent numbers while continuously pressing the Inc button 106a or the Dec button 106b of FIG. 1, for example, the Piano 4 timbre shown in FIG. When the waveform data is selected, the waveform data is transferred from the large-capacity flash memory 204 to one waveform area on the waveform memory 206 (waveform area 2 in the example of FIG. 3). The waveform data of the Piano 3 timbre and Piano 5 timbre that can be selected before and after the Piano 4 timbre by the Inc button 106 a or the Dec button 106 b are respectively stored in the other two waveform areas on the waveform memory 206 from the large-capacity flash memory 204 (example in FIG. In the waveform areas 1 and 3), background processing in parallel with sound generation processing Therefore, to be transferred. Thus, when the performer designates the next tone color by using the Inc button 106a or the Dec button 106b, the tone generator LSI 205 instantaneously switches the waveform area on the waveform memory 206 and outputs the waveform data of the switched tone color as an output musical tone. It becomes possible to output as waveform data, and silence can be kept to a minimum.

  FIG. 4 is a diagram showing a data configuration example of a flash memory tone color information table for managing waveform data on the large-capacity flash memory 204 stored in the ROM 202 of FIG. As illustrated in FIG. 4, an entry for each timbre in the flash memory timbre information table includes a “number” item value indicating a timbre number, a “timbre name” item value, and waveform storage in the large-capacity flash memory 204. A “waveform address offset” item value indicating the offset (hexadecimal number) of the storage address from the head of the area and a “waveform size” item value indicating the entire waveform size (hexadecimal number) of the waveform data group included in the timbre It is remembered.

  In the present embodiment, the CPU 201 continuously operates the Inc button 106a or the Dec button 106b in FIG. 1 when detecting that the performer sequentially performs a tone color comparison operation for selecting a tone color. Therefore, it is determined that there is a high possibility of selecting a timbre, and as the next waveform data, the waveform data of each timbre number ± 1 with respect to the timbre number following the waveform data of the currently selected timbre number Are transferred from the large-capacity flash memory 204 to the waveform memory 206 with priority. Such a state is referred to as a second mode state, that is, a “sequential tone color comparison state”.

  For this reason, in the present embodiment, a process for sequentially detecting the timbre comparison state is required. In the present embodiment, whether or not the current state is the sequential tone color comparison state is determined based on whether or not the Inc button 106a or the Dec button 106b is operated and the frequency of tone color switching. When compared with the normal performance state, in the timbre comparison state, the performer operates the Inc button 106a or the Dec button 106b and selects a plurality of timbres within a short period of time for comparison. There are many. Therefore, in the present embodiment, when the performer selects a certain tone color, the CPU 201 performs a tone color selection operation with the Inc button 106a or the Dec button 106b, and the previous two tone color selections are also performed in accordance with the Inc button 106a or the Dec button 106b. If it is performed by the button 106a or the Dec button 106b and has occurred within 30 seconds, it is difficult to consider it as a normal performance, so it is determined that the current state is a sequential tone color comparison state.

  In this embodiment, the CPU 201 always obtains information on the button operated at the time of the previous two timbre switchings and the generation time in order to perform the above-described sequential timbre comparison state determination and key range determination. In the present embodiment, the above time measurement and management is performed using a timer counter. This counter is a 16-bit free running timer counter 212 shown in FIG. 2 that continues to increment every second. When an event occurs, this value is read and the time is recorded, and the elapsed time is calculated by comparison with the current value of this timer. This timer returns to 0 when the maximum value is exceeded, but there is no problem because the elapsed time is calculated by unsigned subtraction of the current 16-bit timer value.

  Next, processing at the time of waveform switching in the present embodiment will be described. First, when a timbre comparison / selection operation occurs, the CPU 201 determines whether or not the current state is a timbre comparison state sequentially. When the CPU 201 determines that the timbre comparison state is in sequence, the CPU 201 calculates a timbre number that is currently designated, a timbre number that is +1 with respect to that timbre number, and a timbre number that is -1. If the currently designated tone number is the twentieth tone number in a tone category, the tone number obtained by adding +1 to the tone number is 1 in the tone category next to the tone category. The th tone number is calculated. Alternatively, when the currently designated tone number is the first tone number in a certain tone color category, the tone number obtained by subtracting -1 from the tone number is the tone number of the previous tone category. A twentieth tone color number is calculated. As the timbre numbers, numbers that are serially numbered for each of the 20 timbres in the 16 timbre categories are used. Thereafter, the CPU 201 firstly sets the “waveform address offset” item value of the entry having the value of the currently selected timbre number as the “number” item value on the flash memory timbre information table (see FIG. 4) in the ROM 202. A storage area on the large-capacity flash memory 204 for the waveform data of the timbre is specified from the “waveform size” item value, waveform data corresponding to the currently selected timbre number is read from the area, and the waveform data Are transferred to one waveform area on the waveform memory 206 via the tone generator LSI 205. The waveform area of the waveform memory 206 is a waveform area other than the waveform area in which waveform data equal to the tone number that is currently designated, the tone number that is incremented by one or the tone number that is decremented by -1 is already read, or is being read. Things are specified.

  If a performance occurs before the necessary waveform data is read from the large-capacity flash memory 204 into the waveform memory 206, no sound can be produced, but a sound generation process is performed when a key is pressed on the waveform data of the tone that has been read. It can be performed.

  Even during the performance, the CPU 201 assigns the second and third priorities to the timbre number incremented by +1 and the timbre number decremented by -1 with respect to the currently selected timbre number by background processing. From the “Waveform Address Offset” item value and “Waveform Size” item value of the entry having those tone number values in the “Number” item value on the flash memory tone information table (see FIG. 4), those tone colors Each storage area of the waveform data corresponding to the number on the large-capacity flash memory 204 is specified, each waveform data corresponding to the tone color number is read from the storage area, and the waveform data is read via the tone generator LSI 205 Transfer to one waveform area on the waveform memory 206. Thus, when the performer presses the Inc button 106a or the Dec button 106b, the CPU 201 can align the waveform data of the newly designated tone number in the waveform memory 206 in a short time, and then the tone generator LSI 205. Can immediately execute sound generation processing based on the waveform data of the newly specified tone color number.

  When the CPU 201 determines that the current state is not the sequential tone color comparison state, first, the “waveform address offset” item value and the “waveform” of the entry having the value of the currently selected tone number as the “number” item value The storage area of the timbre waveform data on the large-capacity flash memory 204 is identified from the “size” item value, the waveform data corresponding to the currently selected timbre number is read from the area, and the waveform data is read out as the sound source The data is transferred to one waveform area on the waveform memory 206 via the LSI 205.

  FIG. 5 is a diagram showing a list of variables on the RAM 203 used in the control process executed by the CPU 201 of FIG. Each variable will be described in detail in the detailed description of the control process described later.

  Below, the detailed example of the control processing which CPU201 performs in order to implement | achieve the above-mentioned operation | movement is demonstrated.

  FIG. 6 is a flowchart of a main routine showing an example of the entire control process executed by the CPU 201. This processing example is a processing example in which the CPU 201 executes a control program stored in the ROM 202.

  The CPU 201 first initializes the contents of the RAM 203 (step S601), and then enters a steady loop process indicated by a series of processes from steps S602 to S611.

  In the steady loop process, the CPU 201 first executes a user interface process (displayed as “user I / F” in the figure) (step S602). Here, the CPU 201 acquires the states of the tone color selection button 102, the Inc button 106a, and the Dec button 106b in FIG. 1 via the key scanner 207 in FIG. Next, as a result of the processing in step S602, the CPU 201 determines whether or not a timbre selection event has occurred by the player operating the timbre selection button 102, the Inc button 106a, or the Dec button 106b (step S603). . Then, when timbre switching occurs (when the determination in step S603 is Yes), the CPU 201 executes timbre switching processing (step S604).

  Next, the CPU 201 executes keyboard processing (step S605). Here, the CPU 201 acquires the key pressing state of the keyboard 105 in FIG. 1 via the key scanner 207 in FIG. Next, as a result of the processing in step S605, the CPU 201 determines whether or not a key pressing event has occurred when the performer presses any key on the keyboard 105 (step S606). When the key depression event occurs (when the determination in step S606 is Yes), the CPU 201 executes a sound source sound generation process (step S607).

  Subsequently, as a result of the process in step S605, the CPU 201 determines whether or not a key release event has occurred as a result of the player releasing any of the keys pressed on the keyboard 105 (step S608). . Then, when a key release event occurs (when the determination in step S608 is Yes), the CPU 201 executes a sound source release process (step S609).

  Thereafter, the CPU 201 executes a sound source steady service process (step S610). Here, for example, general processing for the electronic keyboard instrument 100 such as processing corresponding to the case where the registration selection button 103 in FIG. 1 is pressed, processing corresponding to the case where the vendor / modulation wheel 104 in FIG. Processing is executed.

  Finally, the CPU 201 executes waveform reading processing (step S611).

  Thereafter, the CPU 201 returns to the beginning of the steady loop process in step S602.

  Hereinafter, the initialization process in step S601, the timbre switching process in step S604, and the waveform reading process in step S611 related to the present embodiment will be described in detail.

  FIG. 7 is a flowchart showing a detailed example of the initialization process in step S601 of FIG.

First, the CPU 201 sets all the values of the “variable” shown in FIG.
(Step S701).

  However, the tone color selection button element TS_HIS [i]. BUTTON (i = 0, 1), timbre serial number WM_ST [i]. Invalid for each variable of TONE (i = 1, 2), tone number RT [i] (i = 0, 1, 2) of the waveform to be read, and number READING_WAVE of the waveform currently being read (see FIG. 5) The value “−1” which means that is stored again. That is, the CPU 201 executes the following series of processes.

  First, after storing the initial value “0” in the variable i in step S702, the CPU 201 increments the value of the variable i by +1 in step S705, and determines that the value of the variable i becomes 1 in step S704. Step S703 is executed for each iteration. In step S703, the CPU 201 determines the tone color selection button element TS_HIS [i]. The invalid value “−1” is stored in BUTTON (see FIG. 5). This process is performed twice for the variable i specified as 0 and 1, whereby the timbre selection button elements TS_HIS [i]. BUTTON [0]. TONE and TS_HIS [i]. BUTTON [1]. An invalid value “−1” is stored in each TONE.

  Next, after storing the initial value “1” in the variable i in step S706, the CPU 201 determines that the value of the variable i has become 2 in step S708 while incrementing the value of the variable i by +1 in step S709. Step S707 is executed for each repetition until the first time. In step S707, the CPU 201 determines the timbre serial number WM_ST [i]. The invalid value “−1” is stored in TONE (see FIG. 5). This process is executed twice for the value of 1 and 2 specified as the value of the variable i, so that the timbre serial number WM_ST [1]. TONE and WM_ST [2]. An invalid value “−1” is stored in each TONE.

  Subsequently, after storing the initial value “0” in the variable i in step S710, the CPU 201 determines that the value of the variable i has become 2 in step S713 while incrementing the value of the variable i by +1 in step S714. Step S712 is executed for each iteration until the first time. In step S712, the CPU 201 stores the invalid value “−1” in the tone number RT [i] (see FIG. 5) of the waveform to be read designated by the variable i. By executing this process for three times when 0, 1, and 2 are designated as the value of the variable i, the tone numbers RT [0], RT [1], and RT [2] of the waveform to be read are Each invalid value “−1” is stored.

  Finally, the CPU 201 stores an invalid value “−1” in the variable of the waveform number READING_WAVE (see FIG. 5) currently being read (step S715). Thereafter, the CPU 201 ends the initialization process of step S601 of FIG. 6 illustrated by the flowchart of FIG.

  FIG. 8 is a flowchart showing a detailed example of the timbre switching process in step S604 of FIG. Here, the timbre category number selected by the player by operating the category button in the timbre selection button 102 is set in the variable CC on the RAM 203, and the timbre number in the timbre selection button 102 by the player is also set in the variable CT. The timbre number selected by operating the button (the timbre number specified in the timbre category) is set, the timer value of the current 16-bit free running timer counter 212 is also set in the variable T, and the performance is also set in the variable B. It is assumed that information on the user operating the Inc button 106a or the Dec button 106b (B = 1 when the Inc button 106a is operated, B = 0 when the Dec button 106b is operated) is set.

  First, the CPU 201 sequentially executes a timbre comparison state determination subroutine (step S801 in FIG. 8). As a result, the presence or absence of the tone color comparison state is sequentially set in the variable s on the RAM 203. When this value is “1”, this indicates that the current state is a sequential tone comparison state in which the player selects a favorite tone while switching a number of tones one after another and performing a trial performance. In this case, the timbre comparison state is not in effect (normal mode state).

  Subsequently, the CPU 201 determines whether or not the value of the variable s obtained in step S801 is 1, that is, whether or not the current state is a sequential tone color comparison state (step S802).

  If the current state is not the sequential tone color comparison state (No in step S802), the CPU 201 executes a first mode state, that is, a normal state read tone number determination subroutine (step S803). Here, processing corresponding to the case where the performer selects a normal timbre number is executed.

  On the other hand, if the current state is not the sequential timbre comparison state (if the determination in step S802 is No), the CPU 201 executes a sequential timbre comparison state read timbre number determination subroutine (step S804). Here, processing corresponding to the case where the performer performs an operation of successively selecting the timbres of adjacent numbers while continuously pressing the Inc button 106a or the Dec button 106b in order to perform the timbre selection. .

  After the processing of step S803 or S804, the CPU 201 executes a read tone number setting subroutine (step S805). Here, preparation setting processing such as setting of the waveform reading priority for transferring the waveform data corresponding to the timbre number determined in step S803 or S804 from the large-capacity flash memory 204 to the waveform memory 206 is performed. Executed.

  Finally, the CPU 201 executes a timbre switching history processing subroutine (step S806). Here, a history of operation buttons and selection times in the last two timbre selections is recorded.

  FIG. 9 is a flowchart showing a detailed processing example of the sequential tone color comparison state determination subroutine in step S801 of FIG.

  First, the CPU 201 determines whether or not the performer has operated either the Inc button 106a or the Dec button 106b, that is, whether or not the value of the variable B on the RAM 203 is “0” or “1”. (Step S901). When the performer presses the Inc button 106a in FIG. 1 to select a timbre, B = 1 is set, and when the Dec button 106b is pressed, B = 0 is set. When the timbre selection button 102) is pressed, for example, B = -1 is set.

  If the determination in step S901 is No, the CPU 201 sets that the current state is the normal state by setting a value “0” to the variable s (step S910). Thereafter, the CPU 201 ends the sequential tone color comparison state determination subroutine of step S801 of FIG. 8 illustrated by the flowchart of FIG.

  If the determination in step S901 is Yes, the CPU 201 sets the old tone color of the two previous tone color selections specified by the tone color selection history buffer write pointer TS_WP, which is a variable on the RAM 203, to the variable T_OLD on the RAM 203. Time element TS_HIS [TS_WP]. The value of TIME is stored (step S902). Note that the value of the timbre selection history buffer write pointer TS_WP is determined by the processing of steps S1402 to S1404 in FIG. doing.

  Next, the CPU 201 stores the current timer value of the 16-bit free running timer counter 212 in a variable T_CUR on the RAM 203 (step S903).

  Then, the CPU 201 determines whether or not the elapsed time from the older timbre selection to the current timbre selection of the past two timbre selections obtained by subtracting the value of the variable T_OLD from the value of the variable T_CUR is shorter than 31 seconds. Is determined (step S904).

  If the determination in step S904 is No, the CPU 201 sets that the current state is the normal state by setting the value “0” to the variable s (step S910). Thereafter, the CPU 201 ends the sequential tone color comparison state determination subroutine of step S801 of FIG. 8 illustrated by the flowchart of FIG.

  On the other hand, if the determination in step S904 is Yes, the CPU 201 sets a value “0” to the variable i on the RAM 203 in step S905, and then increments the value of the variable i by +1 in step S907, while the variable in step S908. The determination process in step S906 is executed until it is determined that the value of i exceeds 1. In each repeated execution of step S906, the CPU 201 performs the timbre selection operation button element TS_HIS [i]. In the timbre selection history buffer, which is a variable on the RAM 203, for the past two times indicated by each value of the variable i. Whether or not the value of BUTTON is “0” or “1”, that is, whether or not the timbre selection operation by the player in the past two has been performed by either the Inc button 106a or the Dec button 106b. Determine.

  If the determination in step S906 is No, the CPU 201 sets that the current state is the normal state by setting a value “0” to the variable s (step S910). Thereafter, the CPU 201 ends the sequential tone color comparison state determination subroutine of step S801 of FIG. 8 illustrated by the flowchart of FIG.

  After the determination in step S906 corresponding to both the variables i = 0 and 1 is Yes, the value of the variable i is “2” in step S907 and the determination in step S908 is Yes, the CPU 201 determines that the variable s By setting the value to “1”, the current state changes to a sequential tone comparison state in which the performer switches a number of tones one after another using the Inc button 106a or the Dec button 106b and selects a favorite tone while performing a trial performance. Something is set (step S909). Thereafter, the CPU 201 ends the sequential tone color comparison state determination subroutine of step S801 of FIG. 8 illustrated by the flowchart of FIG.

  FIG. 10 is a flowchart showing a detailed process example of the normal state read tone number determination subroutine in step S803 of FIG.

  First, as shown in the following equation (1), the CPU 201 designates the currently designated tone category number CC stored in the variable CC on the RAM 203 and the current designation stored in the variable CT as well. Based on the timbre number CT in the timbre category, a continuous timbre number (see the description of FIG. 4) on the large-capacity flash memory 204 is calculated, and the calculation result is a waveform to be read which is a variable on the RAM 203. Is stored in the first element RT [0] of the timbre number (step S1001).

    RT [0] = CC × 20 + CT (1)

  Subsequently, the CPU 201 stores the invalid value “−1” in each of the second and third elements RT [1] and RT [2] of the timbre number of the waveform to be read which is a variable on the RAM 203 (step S1). S1002, S1003). Thereafter, the CPU 201 ends the processing of the normal state read tone number determination subroutine of step S803 of FIG. 8 illustrated in the flowchart of FIG.

  When the performer performs a normal tone selection operation by the above-described normal state read tone number determination subroutine, the waveform data to be read corresponds to the tone number (serial number) selected by the performer. Only the setting for transferring only the waveform data from the large-capacity flash memory 204 to the waveform memory 206 is performed.

  FIG. 11 is a flowchart showing an example of detailed processing of the read tone color number determination subroutine for the sequential tone color comparison state in step S804 of FIG.

  The CPU 201 first determines whether or not the value of the variable B on the RAM 203 is 0, that is, whether the performer has pressed the Dec button 106b or the Inc button 106a (step S1101).

  If the determination in step S1101 is No, that is, if it is determined that the performer has pressed the Inc button 106a, the CPU 201 first increments the value of the variable CT specifying the timbre number in the timbre category on the RAM 203 by +1 (step S1102). .

  Next, the CPU 201 sets the timbre number (serial number) newly designated at the first element value RT [0] of the timbre number of the waveform to be read by a series of processing from step S1103 to S1105. That is, the CPU 201 first determines whether or not the value of the variable CT incremented in step S1102 has become a value “20” that exceeds the maximum value “19” of timbre numbers that can be specified within one timbre category ( Step S1103). If the determination in step S1103 is Yes, the CPU 201 increments the value of the variable CC indicating the timbre category number by +1, and indicates the value of the variable CT indicating the timbre number indicating the first timbre number in the timbre category indicated by the variable CC. The value is set to “0” (step S1104). By this process, when the Inc button 106a is pressed in a state where the last timbre number in a certain timbre category is designated, the first timbre number in the next timbre category is designated. If the Inc button 106a is pressed in a state where the last timbre number in the last (16th) timbre category is specified, for example, the timbre number is not increased so that the process of step S1104 is not executed. May be controlled so as not to advance. If the determination in step S1103 is No, the CPU 201 skips the process in step S1104, thereby maintaining the state where the timbre number is simply incremented by 1 in the current timbre category in step S1102. Thereafter, the CPU 201 uses the same timbre category number CC stored in the variable CC on the RAM 203 as the variable (CT) based on the following formula (2) similar to the formula (1) described above in step S1001 of FIG. Timbre number newly stored by the operation of the Inc button 106a based on the timbre number CT in the timbre category stored in (a timbre number on the large-capacity flash memory 204 (see the description of FIG. 4) )), And the calculation result is stored in the first element RT [0] of the tone number of the waveform to be read which is a variable on the RAM 203 (step S1105).

    RT [0] = CC × 20 + CT (2)

  Subsequently, the CPU 201 performs a series of processing from step S1106 to step S1109 to set the timbre number (serial number) obtained by adding +1 to the newly designated timbre number to the second element value RT [1] of the timbre number of the waveform to be read. (Hereinafter referred to as “+1 tone number”). That is, the CPU 201 first stores a value obtained by adding 1 to the value of the variable CT incremented in step S1102 in the variable CT ′ on the RAM 203 (step S1106). Next, the CPU 201 determines whether or not the value of the variable CT ′ has reached a value “20” that exceeds the maximum value “19” of timbre numbers that can be specified within one timbre category (step S1107). If the determination in step S1107 is Yes, the CPU 201 stores the value obtained by incrementing the value of the variable CC indicating the timbre category number by +1 in the variable CC ′ on the RAM 203, and the variable CT ′ indicating the +1 timbre number. Is set to a value “0” indicating the first timbre number in the timbre category indicated by the variable CC ′ (step S1108). With this processing, when the variable CT points to the last timbre number (= 19) in a certain timbre category by operating the Inc button 106a, the first timbre number in the next timbre category is designated as the +1 timbre number. Will be. If the determination in step S1107 is No, the CPU 201 skips the process in step S1108 and maintains the calculation result of the variable CT ′ in step S1106. Thereafter, the CPU 201, based on the following equation (3), the timbre category number CC ′ stored in the variable CC ′ on the RAM 203 and the timbre number CT ′ within the timbre category also stored in the variable CT ′. Based on the above, the timbre number obtained by adding 1 to the timbre number newly designated by the operation of the Inc button 106a is calculated, and the calculation result is used as the second element RT of the timbre number of the waveform to be read which is a variable on the RAM 203. Stored in [1] (step S1109).

    RT [1] = CC ′ × 20 + CT ′ (3)

  If the variable CT indicates the last timbre number (= 19) in the last (16th) timbre category by operating the Inc button 106a, for example, RT [1] = − 1 (invalid value) It may be controlled so that the +1 tone number is not specified.

  Subsequently, the CPU 201 performs a series of processing in steps S1110 to S1113, and a timbre number (serial number) obtained by subtracting the timbre number newly designated by -1 in the third element value RT [2] of the timbre number of the waveform to be read. ) (Hereinafter referred to as “-1 tone number”). That is, the CPU 201 first stores a value obtained by subtracting -1 from the value of the variable CT incremented in step S1102 in the variable CT 'on the RAM 203 (step S1110). Next, the CPU 201 determines whether or not the value of the variable CT ′ has become a negative value that is below the minimum value “0” of timbre numbers that can be specified within one timbre category (step S1111). If the determination in step S1111 is Yes, the CPU 201 stores the value obtained by decrementing the value of the variable CC indicating the timbre category number by −1 in the variable CC ′ on the RAM 203 and also the variable indicating the timbre number of −1. The value of CT ′ is set to a value “19” indicating the last timbre number in the timbre category indicated by the variable CC ′ (step S1112). By this process, when the variable CT indicates the first timbre number (= 0) in a certain timbre category by the operation of the Inc button 106a, the last timbre in the previous timbre category is set as the timbre number of -1. A number will be specified. If the determination in step S1111 is No, the CPU 201 skips the process in step S1112 and maintains the calculation result of the variable CT ′ in step S1110. Thereafter, the CPU 201, based on the following equation (4), the timbre category number CC ′ stored in the variable CC ′ on the RAM 203 and the timbre number CT ′ within the timbre category also stored in the variable CT ′. Based on the above, the timbre number newly calculated by decrementing the timbre number designated by the operation of the Inc button 106a is calculated, and the calculated result is used as the third element of the timbre number of the waveform to be read which is a variable on the RAM 203. Store in RT [2] (step S1113).

    RT [2] = CC ′ × 20 + CT ′ (4)

  Thereafter, the CPU 201 ends the processing of the sequential tone color comparison state read tone number determination subroutine of step S804 of FIG. 8 exemplified by the flowchart of FIG.

  On the other hand, if the determination in step S1101 is Yes, that is, if it is determined that the performer has pressed the Dec button 106b, the CPU 201 first decrements the value of the variable CT that specifies the timbre number in the timbre category on the RAM 203 by −1 ( Step S1114).

  Next, the CPU 201 sets the newly designated tone number (serial number) as the first element value RT [0] of the tone number of the waveform to be read by a series of processing from steps S1115 to S1117. That is, the CPU 201 first determines whether or not the value of the variable CT decremented in step S1114 has become a negative value that is less than the minimum value “0” of timbre numbers that can be specified in one timbre category (step S1115). ). If the determination in step S1115 is Yes, the CPU 201 decrements the value of the variable CC indicating the timbre category number by −1 and sets the value of the variable CT indicating the timbre number to the last timbre number in the timbre category indicated by the variable CC. The indicated value “19” is set (step S1116). With this process, when the Dec button 106b is pressed in a state where the first timbre number in a certain timbre category is designated, the last timbre number in the previous timbre category is designated. If the Dec button 106b is pressed in a state where the first timbre number in the first (first) timbre category is specified, for example, the timbre number is increased so that the process of step S1116 is not executed. May be controlled not to return. If the determination in step S1115 is No, the CPU 201 skips the process in step S1116, thereby maintaining the state where the timbre number is simply set to -1 in the current timbre category in step S1114. Thereafter, the CPU 201 uses the same formula (2) as in step S1115 to set the timbre category number CC stored in the variable CC on the RAM 203 and the timbre in the timbre category also stored in the variable CT. Based on the number CT, a timbre number newly designated by the operation of the Dec button 106b is calculated, and the calculation result is used as the first element RT [0] of the timbre number of the waveform to be read which is a variable on the RAM 203. (Step S1117).

  Subsequently, the CPU 201 performs a series of processes from step S1118 to step S1121 to set a timbre number (-) to the second element value RT [1] of the timbre number of the waveform to be read newly minus the timbre number designated at present. 1 tone number). That is, the CPU 201 first stores a value obtained by decrementing the value of the variable CT decremented in step S1114 by −1 in the variable CT ′ on the RAM 203 (step S1118). Next, the CPU 201 determines whether or not the value of the variable CT ′ has become a negative value that is below the minimum value “0” of timbre numbers that can be specified within one timbre category (step S1119). If the determination in step S1119 is Yes, the CPU 201 stores a value obtained by decrementing the value of the variable CC indicating the timbre category number by −1 in the variable CC ′ on the RAM 203, and a variable indicating the timbre number of −1. The value of CT ′ is set to a value “19” indicating the last timbre number in the timbre category indicated by the variable CC ′ (step S1120). With this processing, when the variable CT indicates the first timbre number (= 0) in a certain timbre category by the operation of the Dec button 106b, the last timbre in the previous timbre category is set as the timbre number of -1. A number will be specified. If the determination in step S1119 is No, the CPU 201 skips the process in step S1120 and maintains the calculation result of the variable CT ′ in step S1118. Thereafter, based on the same expression (3) as in step S1109, the CPU 201 stores the timbre category number CC ′ stored in the variable CC ′ on the RAM 203 and the timbre category stored in the variable CT ′. Based on the timbre number CT ′ at, a timbre number obtained by decrementing the timbre number newly designated by the operation of the Dec button 106 b is calculated, and the calculated result is used as the timbre of the waveform to be read which is a variable on the RAM 203 The number is stored in the second element RT [1] (step S1121).

  When the variable CT indicates the first timbre number (= 0) in the first (first) timbre category by operating the Dec button 106b, for example, RT [1] =-1 (invalid value) It may be controlled so that the tone number of -1 is not specified.

  Subsequently, the CPU 201 performs a series of processes in steps S1122 to S1125 to add a timbre number (+1) to the third element value RT [2] of the timbre number of the waveform to be read by adding +1 to the newly designated timbre number. Set the tone number. That is, the CPU 201 first stores a value obtained by adding 1 to the value of the variable CT decremented in step S1114 in the variable CT ′ on the RAM 203 (step S1122). Next, the CPU 201 determines whether or not the value of the variable CT ′ has become a value “20” that exceeds the maximum value “19” of timbre numbers that can be specified within one timbre category (step S1123). If the determination in step S1123 is Yes, the CPU 201 stores the value obtained by incrementing the value of the variable CC indicating the timbre category number by +1 in the variable CC ′ on the RAM 203, and the variable CT ′ indicating the +1 timbre number. Is set to a value “0” indicating the first timbre number in the timbre category indicated by the variable CC ′ (step S1124). With this processing, when the variable CT indicates the last tone number (= 19) in a certain tone category by operating the Dec button 106b, the first tone number in the next tone category is designated as the tone number of +1. Will be. If the determination in step S1123 is No, the CPU 201 skips the process in step S1124 and maintains the calculation result of the variable CT ′ in step S11222. Thereafter, based on the same expression (4) as in step S1113, the CPU 201 stores the timbre category number CC ′ stored in the variable CC ′ on the RAM 203 and the timbre category stored in the variable CT ′. The tone number obtained by adding +1 to the tone number newly designated by the operation of the Dec button 106b is calculated on the basis of the tone number CT ′ at, and the calculated result is used as the tone number of the waveform to be read which is a variable on the RAM 203. In the third element RT [2] (step S1125).

  Thereafter, the CPU 201 ends the processing of the sequential tone color comparison state read tone number determination subroutine of step S804 of FIG. 8 exemplified by the flowchart of FIG.

  As described above, when the performer presses the Inc button 106a, the first element RT [0], the second element RT [1], and the third element RT [ 2] stores the newly incremented current timbre number, +1 timbre number, and -1 timbre number. When the performer presses the Dec button 106b, the first element RT [0], the second element RT [1], and the third element RT [2] of the tone number of the waveform to be read are The newly decremented current timbre number, -1 timbre number, and +1 timbre number are stored. Here, the timbre number element number (0, 1, 2) of the waveform to be read is stored in the three waveform areas in the waveform memory 206 from the large-capacity flash memory 204. (Refer to FIG. 3) shows the transfer priority. That is, when the performer presses the Inc button 106a, the waveform data of the newly incremented current tone number stored in the first element RT [0] is transferred first, and the second element RT. The waveform data of the +1 tone color number stored in [1] is transferred next, and the waveform data of the -1 tone number stored in the third element RT [2] is transferred last. The This is because the player tends to press the Inc button 106a again when he / she presses the Inc button 106a once when selecting a timbre, so the waveform data of the current timbre number is transferred first, This is because it is efficient to transfer the waveform data of the timbre number incremented by +1 and set the priority of the waveform data of the timbre number decremented by -1 by the operation of the Dec button 106b to the lowest. Conversely, when the performer presses the Dec button 106b, the newly decremented current tone number waveform data stored in the first element RT [0] is transferred first, and the second element Control is performed so that the waveform data of -1 tone color number stored in RT [1] is transferred next, and the waveform data of +1 tone color number stored in the third element RT [2] is transferred last. Is done. This is because the player tends to press the Dec button 106b again when the Dec button 106b is pressed once at the time of selecting a tone, so the waveform data of the current tone number is transferred first, This is because it is efficient to transfer the waveform data of the timbre number decremented by 1 and transfer the waveform data of the timbre number incremented by the operation of the Inc button 106a to the lowest priority.

  12 and 13 are flowcharts showing a detailed processing example of the read tone number setting subroutine in step S805 of FIG. Here, the transfer of the waveform data corresponding to the tone number obtained in the element value RT [0] of the tone number of the waveform to be read in the RAM 203 in the normal state reading tone number determination subroutine in step S803 of FIG. A process of allocating to one of the three waveform areas on the memory 206 (element values RT [1] and RT [2] are set to invalid values “−1”), or FIG. In step S804, the three tone values RT [0], RT [1], and RT [2] of the tone number of the waveform to be read on the RAM 203 in the sequential tone color comparison state read tone number determination subroutine in the RAM 203 are obtained. A process of assigning the transfer with the priority order of each waveform data corresponding to the tone color number to the three waveform areas on the waveform memory 206 is executed.

  First, the CPU 201 performs element values RT [0], RT [1], and RT [2] of the tone number of the waveform to be read on the RAM 203 by a player's tone selection operation in a series of processing from steps S1201 to S1213. Waveform data corresponding to one (in the case of step S803 in FIG. 8) or three (in the case of step S804 in FIG. 8) timbre numbers obtained as three waveform areas (see FIG. 3) Check whether it exists above or is currently being read. The states of the three waveform areas are stored in waveform memory statuses WM_ST [0], WM_ST [1], and WM_ST [2] that are structure variables on the RAM 203. Therefore, the CPU 201 stores “0” in the variable w on the RAM 203 for designating each of the three waveform areas in step S1201, and then increments the value of the variable w by +1 in step S1212, and in step S1213. Until it is determined that the value of the variable w has reached “3”, the series of processing from step S1202 to S1211 is repeatedly executed three times, thereby obtaining the waveform memory status WM_ST [w] corresponding to each waveform area w. Each of the three element values RT [r] (r = 0, 1, 2) of the timbre number of the waveform to be read is compared. In this case, the CPU 201 stores “0” in the variable r on the RAM 203 for designating the timbre number of the waveform to be read in step S1202 in each iteration, and then increments the value of the variable r by +1 in step S1210. However, until it is determined in step S1211 that the value of the variable r has reached “3”, the waveform memory status WM_ST [w] is read by repeatedly executing a series of processes from step S1203 to S1209 three times. Comparison is made with each element value RT [r] of the timbre number of the scheduled waveform.

  In the double repetition process, the CPU 201 first determines whether or not the element value RT [r] of the tone number of the waveform to be read is an invalid value “−1” (step S1203).

  If the determination in step S1203 is Yes, the CPU 201 shifts control to the process in step S1210, and shifts to a process corresponding to the next timbre number of the waveform to be read corresponding to the value of the next variable r.

  If the determination in step S1203 is No, the CPU 201 next selects the timbre serial number WM_ST [w]. In the waveform memory status indicating the continuous timbre number of the waveform area indicated by the variable w (see the description of FIG. 4 and FIG. 5). It is determined whether TONE matches the value of the element value RT [r] of the tone color number of the waveform to be read (step S1204).

  If the determination in step S1204 is No, the CPU 201 shifts the control to the process in step S1210, and shifts to a process corresponding to the next timbre number of the waveform to be read corresponding to the value of the next variable r.

  If the determination in step S1204 is Yes, the CPU 201 continues with an element value WM_ST [w] .W indicating whether or not there is waveform data in the waveform area indicated by the variable w on the waveform memory 206. It is determined whether or not WAVE (see FIG. 5) is a value “1” indicating “present” (step S1205).

  If the determination in step S1205 is Yes, the CPU 201 advances the control to step S1207.

  If the determination in step S1205 is No, the CPU 201 determines that the value of the variable READING_WAVE (see FIG. 5) on the RAM 203 indicating the number of the waveform currently being read is the value of the element value RT [r] of the tone number of the waveform to be read. Is determined (step S1206).

  If the determination in step S1206 is No, the CPU 201 shifts the control to the process in step S1210, and shifts to a process corresponding to the next timbre number of the waveform to be read corresponding to the value of the next variable r.

  If the determination in step S1206 is Yes, the element value RT [r] of the timbre number of the waveform to be read corresponding to the variable r is associated with the waveform area indicated by the variable w corresponding to the waveform memory status WM_ST [w]. It is being processed. Accordingly, since the element value RT [r] does not need to be checked with another waveform memory status WM_ST [w], the CPU 201 determines the element value of the tone number of the waveform to be read corresponding to the current variable r. An invalid value “−1” is stored in RT [r] (step S1207).

  Subsequently, the CPU 201 uses the waveform memory status element value WM_ST [w] .P indicating the priority of transfer (reading) from the large-capacity flash memory 204 to the waveform memory 206 in the waveform area corresponding to the current variable w. In PRI (see FIG. 5), the value of the variable r (see the last explanation in FIG. 11) indicating the priority of the element value RT [r] of the tone color number of the waveform to be read newly associated with it is reset. (Step S1208).

  Then, the CPU 201 does not perform a new write to the waveform area corresponding to the current variable w, so that the rewrite protection flag WM_ST [w]. A value “1” indicating protection is stored in PROTECT (see FIG. 5) (step S1209).

  The above processing is repeatedly executed for all values 0, 1, and 2 of the variable r and all values 0, 1, and 2 of the variable w, so that for each of the three waveform areas (waveform memory status), The timbre number of the waveform area matches one of the timbre numbers newly set in the three element values RT [0], RT [1], or RT [2] of the timbre number of the waveform to be read, and the timbre When the waveform data corresponding to the number has already been read into the waveform area or is being read, the waveform area (waveform memory status) is protected. In other words, the waveform data corresponding to the timbre number newly set in the three element values RT [0], RT [1], or RT [2] of the timbre number of the waveform to be read is still in which waveform area. If the waveform data has not been read and is not being read, the waveform data can be newly read into the unprotected waveform area. The process is executed by a series of processes from steps S1214 to S1222 of FIG.

  The CPU 201 stores “0” in the variable r for designating the tone number of the waveform to be read in step S1214, and then increments the value of the variable r by +1 in step S1221, while the value of the variable r is increased in step S1222. Until it is determined that the value reaches “3”, the element value RT [r] of the timbre number of the to-be-read waveform for which the invalid value “−1” is set in step S1215 is processed as the determination is Yes. While removing from the target, the series of processing from step S1216 to S1220 is repeated three times. With this control, the element value RT [r] of the tone color number of the waveform to be read that has not yet been assigned to the waveform area is assigned. In a series of processing from step S1216 to S1220, the CPU 201 stores “0” in the variable w on the RAM 203 for designating each of the three waveform areas in step S1216, and then sets the value of the variable w in step S1219. While incrementing by +1, until the value of the variable w reaches “3” in step S1220, the waveform memory status rewrite protection flag WM_ST [w]. While searching for a PROTECT (see FIG. 5) value of “0” (not protected), in step S1218, the element value RT [ r] is registered in the waveform memory status WM_ST [w] corresponding to the free waveform area.

  That is, the CPU 201 determines in step S1218 that the timbre serial number WM_ST [w]. The element value RT [r] of the tone color number of the waveform to be read is stored in TONE. Further, the CPU 201 sets the waveform memory status waveform reading priority WM_ST [w]. In the PRI (see FIG. 5), the value of the variable r (see the last explanation in FIG. 11) indicating the priority order of the element value RT [r] of the timbre number of the waveform to be read is set. Further, the CPU 201 uses the element value WM_ST [w]. Since the waveform data has not yet been transferred to WAVE (see FIG. 5), a value “0” indicating “none” is set. Further, the CPU 201 stores the waveform memory status read tone waveform data on the flash memory at the storage start address WM_ST [w]. In FLASH_ADRS (see FIG. 5), in the flash memory timbre information table illustrated in FIG. 4 in the ROM 202, the “waveform address” of the entry whose “number” item value is equal to the element value RT [r] of the timbre number of the waveform to be read Set the "Offset" item value (timbre waveform start address). In addition, the CPU 201 calculates the waveform size element value WM_ST [w]. In the WAVE_SIZE, the “waveform size” item value of the entry in which the “number” item value is equal to the element value RT [r] of the timbre number of the waveform to be read in the flash memory timbre information table illustrated in FIG. To do. Then, the CPU 201 transmits an element value WM_ST [w]. Initialize READ_SIZE to the value “0”.

  The above processing is repeatedly executed for all the values 0, 1, and 2 of the variable r and all the values 0, 1, and 2 of the variable w, whereby the waveform to be read that has not been assigned to the waveform area. The element value RT [r] of the timbre number is registered in the waveform memory status WM_ST [w] corresponding to the free waveform area.

  After the determination in step S1222 is Yes, the CPU 201 stores “0” in the variable w on the RAM 203 for designating each of the three waveform areas in step S1223, and then sets the value of the variable w in step S1225. While incrementing by +1, the process of step S1224 is executed until it is determined in step S1226 that the value of the variable w has reached “3”. In step S1224, the CPU 201 rewrites the waveform memory status rewrite protection flag WM_ST [w]. The PROTECT (see FIG. 5) value is reset to “0”. Thereafter, the CPU 201 ends the read tone number setting subroutine in step S805 of FIG. 8 illustrated by the flowcharts of FIGS.

  FIG. 14 is a flowchart showing a detailed processing example of the timbre switching history processing subroutine of step S809 in FIG.

  The CPU 201 selects the tone color selection operation button element TS_HIS [TS_WP]... Of the tone color selection history buffer designated by the tone color selection history buffer write pointer TS_WP (see FIG. 5) which is a variable on the RAM 203. BUTTON (see FIG. 5) and time element TS_HIS [TS_WP]. In TIME (see FIG. 5), the current timbre number and the current time stored in variables B and T are stored (step S1401).

  Here, the CPU 201 increments the value of the timbre selection history buffer write pointer TS_WP by +1 in step S1402 every time the timbre switching history processing subroutine in step S809 of FIG. 8 is executed, and in step S1403 the timbre selection history buffer. It is determined whether or not the value of the write pointer TS_WP is “1”. If the determination in step S1403 is Yes, the CPU 201 returns the value of the timbre selection history buffer write pointer TS_WP to “0” in step S1404. As a result, the value of the timbre selection history buffer write pointer TS_WP changes cyclically between “0” and “1”, and the timbre selection histories for the two latest timbre selection history buffers TS_HIS [0] and TS_HIS [ 1] is obtained cyclically.

  15 and 16 are flowcharts showing a detailed example of the waveform reading process in step S611 of FIG. In order not to stop the sound generation process due to the performance, in the main loop illustrated in FIG. 6, in step S611, the processing is not concentrated only on the waveform reading process in step S611, and other processes are performed in parallel in step S611. In one execution of the waveform reading process, the process is interrupted when a certain amount of memory transfer is completed, and the process is resumed when the waveform transfer program is started again by performing another main loop process. It has become.

  First, in step S1501, the CPU 201 performs various initial settings. Specifically, the CPU 201 sets initial values “0” to the current reading size counter c, the address counter wp on the waveform memory, the highest priority waveform number h, and the waveform number counter w, which are variables on the RAM 203. To do. Further, the CPU 201 stores the lowest priority (priority) value “3” as an initial value in the priority counter p which is a variable on the RAM 203.

  After the above initial setting, the CPU 201 determines whether or not the value of the number READING_WAVE of the waveform currently being read which is a variable on the RAM 203 is an invalid value “−1”, that is, the current waveform data is not read. It is determined whether or not (step S1502).

  If waveform data is not currently read (Yes in step S1502), the CPU 201 sets the value of the waveform number counter w (initialized to the initial value “0” in step S1501). While incrementing by +1 in step S1508, a series of processing from step S1504 to S1507 is repeatedly executed until it is determined in step S1509 that 2 is reached. By repeating this series of processing, the CPU 201 causes the waveform memory status element value WM_ST [w]. The waveform reading priority written in the PRI is sequentially checked, and the waveform data with the highest priority is selected among those that need to be transferred and have not been transferred.

  In a series of processing from steps S1504 to S1507, the CPU 201 firstly sets the waveform memory status element value WM_ST [w] .wm indicating the presence or absence of waveform data in the waveform area on the waveform memory 206 indicated by the waveform number counter w. It is determined whether or not the value of WAVE is “1”, that is, whether or not the transfer of waveform data to the waveform area on the waveform memory 206 indicated by the waveform number counter w has been completed (step S1504).

  If the transfer of the waveform data to the waveform area on the waveform memory 206 indicated by the waveform number counter w has been completed (Yes in step S1504), the waveform data does not need to be further transferred. The process proceeds to step S1508 to proceed to the process for the next waveform number.

  If the transfer of the waveform data to the waveform area on the waveform memory 206 indicated by the waveform number counter w has not been completed (No in step S1504), the CPU 201 determines the waveform size of the waveform memory status indicated by the waveform number counter w. Element value WM_ST [w]. It is determined whether or not WAVE_SIZE is “0” (step S1505). When no waveform data is registered for the “waveform number” item value corresponding to the waveform number counter w on the flash memory tone color information table illustrated in FIG. 4, the “waveform size” item value is “ 0 ”. As described above with reference to step S1218 of FIG. 13, the waveform size element value WM_ST [w]. “0” is set as the speech waveform size in WAVE_SIZE.

  For this reason, WM_ST [w]. If WAVE_SIZE is “0” (Yes in step S1505), there is no waveform data corresponding to the waveform number counter w, so the CPU 201 proceeds to the process in step S1508 and proceeds to the process for the next waveform number. .

  WM_ST [w]. If WAVE_SIZE is not “0” (NO in step S1505), the CPU 201 determines that the waveform memory status element value WM_ST [w]. It is determined whether the waveform reading priority written in the PRI is smaller than the value of the priority counter p (whether the priority is high) (step S1506).

  WM_ST [w]. If the PRI priority is smaller than the value of the priority counter p (Yes in step S1506), the CPU 201 stores and stores the value of the waveform number counter w in the counter variable h. The priority of the counter p is set to WM_ST [w]. Rewriting is performed in the priority order of PRI (step S1507).

  WM_ST [w]. If the PRI priority is not smaller than the value of the priority counter p (No in step S1506), the CPU 201 does not rewrite step S1507.

  In the initial state, the lowest priority “3” is set in the priority counter p (see step S1501). With this as an initial value, the series of processing in steps S1504 to S1507 is repeatedly executed. As a result, the counter variable h finally has a waveform with the highest priority among the waveforms that require waveform transfer and have not been completed. The “waveform number” of the data is obtained. For example, when the performer specifies the timbre number in the normal state, valid data is set only for WM_ST [w] corresponding to any one of w = 0, 1, and 2. Accordingly, in this case, only one “waveform number” of the waveform data corresponding to the timbre number selected by the performer and having not completed waveform transfer is obtained as the counter variable h. On the other hand, when the performer 306 sequentially designates in the timbre comparison state, each WM_ST [w] corresponding to each of w = 0, 1, and 2 includes the timbre number selected by the performer and the timbre number of +1 and Two timbre numbers minus -1 are set. Accordingly, in this case, the “waveform number” of the waveform data corresponding to the timbre number selected by the performer and having not completed waveform transfer is first obtained as the counter variable h.

  As a result of the above repeated processing, when the determination in step S1509 is Yes, the CPU 201 stores the waveform number with the highest priority obtained in the counter variable h in the waveform number READING_WAVE currently being read, which is a variable on the RAM 203, In addition, the element value WM_ST [w]. Indicating the transferred data size of the waveform memory status indicated by the waveform number counter w. READ_SIZE is initially set to a value “0” (a state where transfer has not yet started) (step S1510).

  Thereafter, the CPU 201 proceeds to the processing from step S1511 onward in FIG. 16, and starts the processing of transferring the waveform data of the waveform number obtained in the counter variable h from the large-capacity flash memory 204 to the waveform memory 206.

  If it is determined in step S1502 described above that waveform data is currently being read (NO in step S1502), the CPU 201 is a variable on the RAM 203 in the counter variable h. After storing the value of the currently read waveform number READING_WAVE, the process proceeds to step S1511 and subsequent steps in FIG. 16, and the remaining waveform data of the waveform number obtained in the counter variable h is transferred from the large-capacity flash memory 204 to the waveform memory 206. Execute the process to transfer to.

  In the above transfer process, the CPU 201 first, in the large-capacity flash memory 204, uses WM_ST [h]., Which is the element value of the waveform memory status corresponding to the counter variable h. FLASH_ADRS and WM_ST [h]. One word of waveform data is read from an address obtained by adding READ_SIZE, and substituted into a variable d on the RAM 203 (step S1511). Here, the element value WM_ST [h]. FLASH_ADRS stores the start address on the large-capacity flash memory 204 of the waveform data to be transferred to the waveform area on the waveform memory 206 corresponding to the waveform number indicated by the variable h in step S1218 of FIG. Has been. Also, element value WM_ST [h]. READ_SIZE stores the data size that has been transferred so far. Therefore, “WM_ST [h] .FLASH_ADRS + WM_ST [h] .READ_SIZE” is an address on the large-capacity flash memory 204 to be read next.

  Next, in the waveform memory 206, the CPU 201 stores the start address on the waveform memory 206 of the waveform area corresponding to the counter number corresponding to the counter variable h and the element value of the waveform memory status corresponding to the counter variable h WM_ST [h]. . The waveform data for one word stored in the variable d is written to the address obtained by adding READ_SIZE via the tone generator LSI 205 (step S1512).

  Thereafter, the CPU 201 transmits an element value WM_ST [h] .h indicating the transferred data size of the waveform memory status corresponding to the waveform number indicated by the counter variable h. The value of READ_SIZE is incremented by +1, and the value of the current read size counter c, which is a variable on the RAM 203 (initialized to the value “0” in step S1501), is incremented by +1 (step S1513).

  The CPU 201 then transmits an element value WM_ST [h] .h indicating the transferred data size of the waveform memory status corresponding to the waveform number indicated by the counter variable h. The value of READ_SIZE is the waveform size element value WM_ST [w] .W of the waveform memory status corresponding to the waveform number indicated by the counter variable h. It is determined whether or not it becomes equal to WAVE_SIZE (step S1514). Waveform size element value WM_ST [w]. In WAVE_SIZE, in step S1218 in FIG. 13 in the read tone number setting subroutine in step S805 in FIG. 8 in the tone color switching process in step S604 in FIG. 6, from the flash memory tone information table in the ROM 202 corresponding to the current tone. The “waveform size” item value shown in FIG. 4 is set.

  If the determination in step S1514 is No, the CPU 201 determines whether or not the value of the current read size counter c is equal to 102400 bytes, that is, whether or not the size transferred this time has reached 100 KB (kilobytes). (Step S1515).

  If the determination in step S1515 is No, the CPU 201 returns to the process in step S1511 and continues the transfer.

  If the determination in step S1515 is Yes, the CPU 201 ends the waveform reading process in step S611 of FIG. 6 illustrated in the flowcharts of FIGS. As described above, in the present embodiment, when the memory transfer of a certain capacity (for example, 100 KB) is completed, the process is interrupted, and when the waveform transfer program is started again by performing another main loop process, the process shown in FIG. The process is resumed via steps S1502 to S1503. At this time, the element value WM_ST [w]. Indicating the transferred data size of the waveform memory status indicated by the counter variable h. Since READ_SIZE stores the size that has been transferred up to the previous time by the processing of step S1513 in FIG. 16, the address next to the address for which the previous transfer has been completed by the address calculation processing in steps S1511 and S1512 of FIG. The transfer can be resumed from.

  Element value WM_ST [h]. Indicating the transferred data size. The value of READ_SIZE is the waveform size element value WM_ST [w]. When it becomes equal to WAVE_SIZE (when the determination in step S1514 is Yes), the CPU 201 uses the element value WM_ST [w] .W indicating the presence / absence of a waveform on the waveform memory 206 in the waveform memory status indicated by the counter variable h. A value “1” indicating that the waveform data corresponding to the waveform number indicated by the variable h exists in the waveform area of the waveform memory 206 is set in WAVE (see FIG. 5) (step S1516). Thereafter, the CPU 201 ends the waveform reading process in step S611 of FIG. 6 exemplified by the flowcharts of FIGS.

  When the transfer of the waveform data with the highest priority is completed by the above-described series of processes, the priority is set by steps S1502 to S1504 to S1510 when the waveform reading process in step S611 in FIG. The second highest waveform data transfer is set and transferred, and the waveform data transfer setting with the lowest priority is set and transferred. Specifically, when the performer 306 operates the Inc button 106a, the tone having the second highest priority is transmitted following the transfer of the waveform data corresponding to the tone number having the highest priority selected by the player 306. Waveform data corresponding to the timbre number corresponding to the timbre number obtained by adding +1 is executed, and finally, waveform data corresponding to the timbre number obtained by subtracting -1 from the timbre number having the lowest priority order is executed. On the contrary, when the performer 306 operates the Dec button 106b, the tone having the second highest priority is transmitted following the transfer of the waveform data corresponding to the tone number having the highest priority selected by the performer 306. The waveform data corresponding to the timbre number with the number -1 is transferred, and finally the waveform data corresponding to the timbre number with the lowest priority assigned to the timbre number is transferred (see FIG. 11). (See the last description and the description of step S1208 in FIG. 12).

  As described above, after the transfer of the waveform data to the waveform area on the waveform memory 206 is completed, the CPU 201 performs the sound source sound generation process in step S607 of FIG. Thus, it is possible to instruct the tone generator LSI 205 to perform tone generation processing by reading waveform data in the waveform area. That is, the CPU 201 sets the same value as the timbre number currently selected by the performer in the element value TONE (see FIG. 5) when a key depression event occurs (when the determination in step S606 in FIG. 6 is Yes). The waveform memory status WM_ST [w] being extracted is extracted. Next, the CPU 201 determines the element value WM_ST [w]. It is determined whether or not the value of WAVE (see FIG. 5) is “1”, that is, whether or not the transfer of waveform data to the waveform area on the waveform memory 206 corresponding to the waveform number indicated by the variable w has been completed. To do. If the transfer completion determination is Yes, the CPU 201 instructs the tone generator LSI 205 to generate sound for the waveform area on the waveform memory 206 corresponding to the waveform number indicated by the variable w. If the determination of transfer completion is No, the CPU 201 skips the sound generation processing instruction to the tone generator LSI 205.

  According to the above-described embodiment, it is possible to greatly reduce the silent time in which sound cannot be generated because a desired waveform does not exist in the waveform memory when sequentially switching timbres accompanied by transfer of a plurality of waveforms. Thereby, a player's stress can be reduced or it can be suppressed to the level which does not feel at all. For example, in a case where it is possible to perform with only one waveform data having a capacity of 10% of the waveforms required for one tone, the silent state is reduced to 1/10 unless expected. Will be able to. Even if it is unexpected, reading is performed from the key pressed, so that it is possible to obtain a much shorter silence time than reading everything.
