Description

  The present invention relates to a sound source control device that controls a sound source device that generates a musical sound signal and a computer program applied to the sound source control device.

  Conventionally, for example, as shown in Non-Patent Document 1 below, an electronic musical instrument that assigns a performance pattern to a button and repeatedly reproduces the performance pattern while the button is pressed is known. In this electronic musical instrument, a performance pattern created by a user can be assigned to a button.

"PSR-900 Instruction Manual" (2009 Yamaha Corporation) http://www2.yamaha.co.jp/manual/pdf/emi/japan/port/psr_s900_ja_om_a1.pdf

  However, in the above-described conventional electronic musical instrument, even if the same phrase is included in a part of the performance pattern, data must be created for the entire performance pattern. For example, when creating a four-measure performance pattern data in which the first phrase of one measure length is repeated three times and then the second phrase of one measure length is played once, I had to create 4 bars of data. In this way, the user needs to input data for the same phrase portion, which is troublesome. Further, when two performance patterns differing only in part are required, it is necessary to input the data of these two performance patterns individually, which is troublesome. Also, in order to create complicated performance pattern data, a complicated user interface is required. Specifically, an input operator for inputting a performance pattern, a large display area for displaying the input performance pattern, and the like are required. Further, as described above, one performance pattern tends to be long and complicated, and it is not suitable for a performance form in which improvisation is performed by changing combinations of performance patterns to be reproduced one after another.

  The present invention has been made to address the above problems, and an object of the present invention is a sound source control device for controlling a sound source device and a computer program applied to the sound source control device, which can easily create a performance pattern and improvise It is an object to provide a sound source control device suitable for performance and a computer program applied to the sound source control device. In addition, in the description of each constituent element of the present invention below, in order to facilitate understanding of the present invention, reference numerals of corresponding portions of the embodiment are described in parentheses, but each constituent element of the present invention is The present invention should not be construed as being limited to the configurations of the corresponding portions indicated by the reference numerals of the embodiments.

  In order to achieve the above object, a feature of the present invention is that a plurality of performance operators (P1 to P16) operated by a player and a phrase composed of one or a plurality of musical sounds are set for each performance operator. Phrase setting means (N1 to N4, ND, S20) and one or a plurality of periods among a plurality of periods obtained by dividing a predetermined period common to a plurality of performance operators at equal intervals are selected for each performance operator. A performance pattern setting means (MS1 to MS4, AD, S20) for assigning the set phrase to the selected one or a plurality of periods for each performance operator, and a performance operator In this case, the tone generator for generating a musical tone signal is provided with performance instruction means (S18) for repeatedly performing the performance pattern set in the operated performance operator.

  In this case, the phrase setting means includes the pitch data (NN) relating to the pitch of the one or more musical sounds, the timing data (ND) relating to the sounding start timing of the one or plural musical sounds, and the one or more. One or both of velocity data (VDm) relating to the intensity of the musical tone and gate time data (GD) relating to the length of the one or more musical sounds may be set.

  In the sound source control device configured as described above, since a performance pattern is set by selecting a period during which the set phrase is played, even a long performance pattern can be easily set. In addition, the configuration of the user interface for setting the performance pattern can be simplified.

  In addition, as a period for assigning a phrase, one or a plurality of periods among a plurality of periods obtained by dividing a predetermined period common to a plurality of performance operators at equal intervals are selected. That is, the performance patterns set for the plurality of performance operators have the same length, and the divided periods have the same length. Accordingly, it is possible to synchronize the progress of the performance of the plurality of performance patterns when the plurality of performance operators are operated simultaneously to repeatedly perform the corresponding performance patterns. Moreover, since the performance pattern is composed of short phrases set for each performance operator, performance based on one performance pattern is relatively simple. Therefore, it is suitable for a performance form in which different performance patterns are set for a plurality of performance operators, and combinations of performance operators that are operated simultaneously are changed one after another.

  Another feature of the present invention is that the performance operator is provided with displays (BW1 to BW4) representing the selected period or periods. According to this, since the performer can recognize the period during which the phrase set in the performance operator is played just by looking at the performance operator during the performance, the operability can be improved.

  Furthermore, the implementation of the present invention is not limited to the invention of the sound source control device, but can also be implemented as an invention of a computer program applied to the device.

When the user touches the icon of the sound source control program and selects the sound source control program, the CPU 17a executes the sound source control program and displays a basic image as shown in FIG.

  Performance buttons P1 to P16 are arranged in a region from the center slightly left of the basic image to the right end. The performance buttons P1 to P16 are arranged four by four in the vertical direction and the horizontal direction, and are displayed in a grid pattern. In the present embodiment, 16 performance buttons are provided, but the number of performance buttons may be increased, or conversely.

  A performance button name BN representing the name of the button is assigned to these performance buttons P1 to P16. In addition, the performance buttons P1 to P16 include a channel number CN representing a MIDI channel number, a note number NN representing a pitch, and a velocity VL representing a sound intensity as musical tone information transmitted to the tone generator device 20. Each is assigned. Up to five pieces of musical tone information M1 to M5 can be assigned to one performance button. However, the number of pieces of musical tone information that can be assigned to one performance button may be increased, or vice versa. In the center of the performance buttons P1 to P16, a character string corresponding to the performance button name BN and the note number NN is displayed. That is, a character string composed of a note name (C, C #... B) and an octave number (“1”, “2”... “8”) corresponding to the note number NN is displayed. In the example of FIG. 2, the performance button name BN is set to “Kick” and the note number NN is set to “35” for the performance button P1, so that “Kick” and “ B1 "is displayed. When a plurality of pieces of musical tone information are assigned to one performance button, character strings corresponding to the note numbers NN of the respective musical tone information are displayed in parallel.

  The user can change the values of the channel number CN, note number NN, and velocity VL. An edit button ED is arranged in an area on the left side of the display area of the performance buttons P1 to P16 in the basic image. In the center of the edit button ED, “EDIT” is displayed. When the edit button ED is pressed, the entire basic image slides upward as shown in FIG. 3, and includes a plurality of key buttons corresponding to the respective keys belonging to the key range of 2 octaves at the lower end of the display 12. The keyboard button KB is displayed. That is, the keyboard button KB includes white key buttons WK1 to WK14 that are buttons representing white keys and black key buttons BK1 to BK10 that are buttons representing black keys. Pitches are assigned to the white key buttons WK1 to WK14 and the black key buttons BK1 to BK10, respectively, and the white key buttons WK1 to WK14 and the black key buttons BK1 to BK10 are sounds assigned to the performance buttons as described later. Used to set high.

  In the state of FIG. 3, “C1” to “B2” are assigned to the white key buttons WK1 to WK14, respectively, and “C #” is assigned to the black key buttons BK1 to BK10 as the pitch. 1 "to" A # 2 "are assigned respectively. In order to indicate the range of the displayed keyboard button KB, “C1” and “C2” are displayed on the white key button WK1 and the white key button WK8, respectively. No pitch is displayed on the white key buttons WK2 to WK7, the white key buttons WK9 to WK14, and the black key buttons BK1 to BK10. When the keyboard button KB area is touched with a finger, pen, etc., by sliding the finger, pen, etc. left and right, the keyboard button KB image is scrolled to the left and right to change the range of the keyboard button KB. Can do. The state where the edit button ED is pressed is referred to as an edit mode, and the state where the edit button ED is not pressed is referred to as a performance mode. The state where the edit button ED is pressed is referred to as an edit mode, and the state where the edit button ED is not pressed is referred to as a performance mode. In order to clarify which mode is the current mode, the display mode (for example, color) of the edit button ED is different between the edit mode and the performance mode.

  In the state of FIG. 3, when any one of the performance buttons P1 to P16 is pressed, as shown in FIG. Switch to the display for editing the settings. For example, when the performance button P1 is pressed in order to edit the setting of the performance button P1, the display of the area in the upper right area of the display 12 that does not overlap the performance button P1 that is the performance button to be edited is displayed. Switch to the display for editing the setting of P1. And the display mode of performance button P1 turns into a display mode different from other performance buttons. An area for displaying the contents of the performance button settings to be edited is referred to as an edit window EW. A title “Pad Edit” representing the editing window EW is displayed at the upper end of the editing window EW.

  A name edit button EN is arranged below the title of the edit window EW. In the center of the name edit button EN, a performance button name BN assigned to the performance button is displayed. In this example, “Kick” is displayed. When the name edit button EN is pressed, a keyboard for inputting characters is displayed below the edit window EW. This keyboard is composed of a plurality of buttons each assigned a character, and the performance button name BN of the performance button can be changed using these buttons. It should be noted that the initial value of the performance button name BN when a new performance button setting is started instead of editing an existing setting is a predetermined character string (for example, “Pad”) and the performance button number “1”. ”To“ 16 ”(“ Pad1 ”,“ Pad2 ”, etc.) are set.

  Also, a musical tone information display area for displaying musical tone information assigned to the performance button is provided below the name editing button EN. This musical tone information display area is composed of five rows, and the first to fifth rows correspond to the musical tone information M1 to M5, respectively. That is, the channel number CN, note number NN, and velocity VL constituting each musical tone information are arranged and displayed in this order in the horizontal direction. In this example, since the musical tone information M1 is only assigned to the performance button P1, the values of the channel number CN, note number NN and velocity VL in the second and subsequent lines are displayed as “...”. .

  When changing the value of the channel number CN, first, the display area of the channel number CN of the musical sound information to be changed is touched. Then, “1” to “16” and “Basic” representing the channel numbers are displayed in a list format around the touched display area (for example, the lower side), and the displayed “1” to “16” are displayed. When one of “Basic” and “Basic” is selected, the value of the channel number CN is changed to the selected channel. When “Basic” is selected, the basic settings set for the entire sound source control device 10 are followed. That is, the channel number CN set in advance for the performance buttons P1 to P16 is followed.

  When the value of the note number NN is changed, the display area of the note number NN of the musical sound information to be changed is touched to set the value of the note number NN to be changeable. Then, the key button corresponding to the desired pitch is pressed on the keyboard button KB. As a result, the value of the note number NN is changed to the desired pitch.

  Further, when changing the value of the velocity VL, first, a display area of the velocity VL of the musical sound information to be changed is touched to set the value in a changeable state. Then, an input button that can be slid left and right is displayed below the musical sound information. The display of the value of the velocity VL of the musical sound information set so that the value can be changed is changed to a value corresponding to the position of the input button in the left-right direction. That is, when the input button is slid and positioned at the left end of the movable range, the display of the value of the velocity VL is changed to the minimum “0”, and the input button IN is positioned at the center of the movable range. Then, the display of the value of the velocity VL is changed to “64” in the center. When the input button is positioned at the right end of the movable range, the display of the value of the velocity VL is changed to the maximum “127”. The input button is moved so that the desired velocity VL value is displayed. When the value is touched, the value is determined as the velocity VL value and the input button display disappears.

  When adding musical tone information, none of the channel numbers CN, note numbers NN, and velocity VL of the existing musical tone information is set to be changeable (for example, after touching the “...” Display area). ), Press the key button corresponding to the pitch of the musical information you want to add. Then, musical tone information is added. The note number NN of the added musical tone information is set to the pitch of the pressed key button. The channel number CN is set to “Basic”, and the velocity VL is set to “100”. In the initial state in which no musical tone information is assigned yet, as described above, initial values such as “Pad1” and “Pad2” are set as the performance button names BN. Is added as the performance button name BN, the note number NN of the added musical tone information is automatically set as the performance button name BN.

  A delete button DL is arranged on the right side of the value of the velocity VL of each tone information. An “x” is displayed in the center of the delete button. When the delete button DL is pressed, the musical tone information on that line is deleted.

  For the performance button, any one of the two performance modes of the normal mode and the sequence mode can be set. The normal mode is a performance mode in which each time the performance buttons P1 to P16 are pressed, a musical sound corresponding to the musical sound information assigned to the pressed performance buttons P1 to P16 is generated and played once. That is, in the normal performance mode, when the performance buttons P1 to P16 are pressed, musical tone information including the channel number CN, note number NN, and velocity VL assigned to the pressed buttons is communicated together with note-on information indicating the start of sound generation. The signal is transmitted to the sound source device 20 via the interface circuit 18. Then, when the pressed button is released, the musical tone information assigned to the button is transmitted to the sound source device 20 through the communication interface circuit 18 together with the note-off information indicating the stop of sound generation. If multiple musical tone information is assigned to a performance button, pressing that performance button will send the musical tone information together with the note-on information, and releasing the performance button will release the musical tone information as note-off information. And sent at the same time. Note that “transmit simultaneously” includes sequentially transmitting each piece of musical tone information together with note-on information or note-off information within a predetermined short time (for example, several milliseconds).

  The sequence mode is a mode in which a performance pattern of 4 bars set for each performance button is repeatedly played. In the sequence mode, when the performance button is pressed, the performance button is turned on to start the performance pattern. Even if the performance button is released in this state, the performance button is kept on. When the performance button is in the ON state, the performance pattern is repeatedly played. Once the performance button is released and the performance button is pressed again, the performance button changes to an off state. When the performance button is in the off state, the performance pattern is stopped. The performance pattern will be described in detail later. In the edit window EW, a performance mode selection button PB for selecting a performance mode is provided on the left side of the name edit button EN. The performance mode selection button PB includes a normal mode button CB and a sequence mode button QB. “Play” is displayed at the center of the normal mode button CB, and “Seq” is displayed at the center of the sequence mode button QB. When the normal mode button CB is pressed, the performance mode of the performance button is set to the normal mode, and when the sequence button QB is pressed, the performance mode of the performance button is set to the sequence mode.

  Next, the performance pattern will be described. One performance pattern can be assigned to one performance button. A phrase that is a one-measure phrase that repeatedly reproduces a musical tone having a pitch assigned to the performance button at equal time intervals can be assigned to the performance button. The user can select the number of times the musical sound is repeated in the phrase from four types. In addition, the user can set the sound intensity for each musical sound (hereinafter referred to as a constituent sound) constituting the phrase. Moreover, although the length of each component sound is common, the user can set the length of this component sound. The phrase set as described above is assigned to one or a plurality of bars selected from the first bar to the fourth bar, thereby forming a performance pattern of four bars. Note that the tempo (number of beats per minute) of the performance pattern is set using a tempo setting button TB described later.

  The operation for setting the above phrase will be specifically described. A performance pattern setting display area is provided below the tone information display area. In the upper left area in the performance pattern setting display area, four kinds of sounding number selection buttons N1 to N4 are displayed in a state of being arranged in the horizontal direction. The pronunciation number selection buttons N1 to N4 are buttons for selecting the number of repetitions of the constituent sounds in the phrase.

  A quarter note is displayed in the center of the pronunciation number selection button N1. When the pronunciation number selection button N1 is pressed, a phrase that generates the musical tone having the pitch assigned to the performance button four times at equal time intervals is selected.

  Similarly to the sounding number selection button N1, the sounding number selection button N2, the sounding number selection button N3, and the sounding number selection button N4 are respectively an eighth note, a triple (fourths / threes) note, and a sixteenth note. When the number of sound generation selection button N2, the number of sound generation selection button N3, and the number of sound generation selection button N4 are pressed, the musical tones assigned to the selected performance button are played eight times, twelve times at equal time intervals, and so on. Each phrase that is pronounced 16 times is selected. FIG. 4 shows an example in which a phrase that generates a musical tone having a pitch assigned to the selected performance button eight times at equal time intervals is selected.

  In addition, bar selection buttons MS1 to MS4 are displayed on the right side of the sounding number selection button N4. “1” to “4” corresponding to the bar numbers are displayed in the center of the bar selection buttons MS1 to MS4, respectively. A phrase is assigned to the measure selected by pressing the measure selection buttons MS1 to MS4. That is, the phrase is played in the selected measure. FIG. 4 shows an example in which the first bar to the third bar are selected.

  The phrase settings and performance pattern settings are stored in the ROM 17c (for example, flash memory) for each performance button as performance pattern information PD. That is, as shown in FIG. 5, the ROM 17c stores the number of pronunciations data ND indicating which number of pronunciations is selected. Also, assignment data AD representing a measure to which a phrase is assigned among the first to fourth measures of the performance pattern is also stored.

  Furthermore, as performance pattern information PD, velocity data VDm (m = 11-14, 21-24, 31-34, 41-44) as a coefficient of velocity VL of each musical sound information, and the length of each constituent sound are represented. Gate time data GD is also stored. The velocity data VDm is stored for each constituent sound.

  For example, when the pronunciation number selection button N1 is pressed and a phrase that is pronounced four times within one measure is selected, each period of one measure that is played at the tempo set by the tempo button TB is divided into four equal periods. The musical tone information assigned to the performance button is set to be transmitted to the tone generator 20 via the communication interface circuit 18 together with the note-on information indicating the start of sound generation. In this case, the velocity value of the constituent sound of the phrase is a value obtained by multiplying the velocity data VDm corresponding to each constituent sound by the velocity VL of the musical sound information. In addition, the musical tone information is set to be transmitted to the sound source device 20 via the communication interface circuit 18 together with the note-off information indicating the stop of sound generation at the timing defined by the set tempo and gate time data GD. Is done. The velocity value in this case is also a value obtained by multiplying the velocity data VDm corresponding to each constituent sound by the velocity VL of the musical tone information. If a plurality of pieces of musical tone information are assigned to the performance button, the musical tone information, together with the note-on information or note-off information, is set at the timing according to the tempo setting and the gate time data GD at the same time. Sent to. The velocity value in this case is also a value obtained by multiplying the velocity data VDm corresponding to each constituent sound by the velocity VL of the musical tone information.

  As in the case where the number of pronunciation selection button N1 is pressed, the number of pronunciation selection button N2, the number of pronunciation selection button N3, and the number of pronunciation selection button N4 are pressed to generate eight times, twelve times and sixteen times within one measure. Even when each phrase is selected, the musical tone information is transmitted to the sound source device 20 together with the note-on information at the beginning timing of each period obtained by dividing each bar period into 8 equal parts, 12 equal parts, and 16 equal parts. To be set. The velocity value in this case is also a value obtained by multiplying the velocity data VDm corresponding to each constituent sound by the velocity VL of the musical tone information. In addition, the musical tone information is set to be transmitted to the tone generator 20 together with the note-off information at a timing defined by the set tempo and gate time data GD. The velocity value in this case is also a value obtained by multiplying the velocity data VDm corresponding to each constituent sound by the velocity VL of the musical tone information.

  Since the number of pronunciations in the phrase when the pronunciation number selection button N4 is pressed is the largest, and the musical tone having the pitch assigned to the performance button is generated 16 times, velocity data VDm is stored for each performance button. For this purpose, 16 storage areas are secured in the RAM 17d. However, the number of pronunciations in the phrase when one of the pronunciation number selection button N1, the pronunciation number selection button N2, and the pronunciation number selection button N3 is pressed is less than 16, so in this case, some Only the storage area is used.

  Specifically, when the pronunciation number selection button N1 is pressed and a phrase that is pronounced four times is selected, the storage area for velocity data VD11, VD21, VD31, and VD41 is used. Also, when the pronunciation number selection button N2 is pressed and a phrase to be generated eight times is selected, the storage area of velocity data VD11, VD13, VD21, VD23... VD43 is used. Further, when the pronunciation number selection button N3 is pressed and a phrase to be pronounced 12 times is selected, the storage areas of velocity data VD11, VD12, VD14, VD21, VD22, VD24... VD44 are used. When the pronunciation number selection button N4 is pressed and a phrase to be generated 16 times is selected, the storage area for all velocity data VDm is used. The value of the velocity data VDm is set to “0” or more and “1” or less.

  Further, the gate time data GD is common to all the constituent sounds of the phrase, and is expressed as a relative value where one beat (quarter note) is “480”. However, the maximum value of the gate time of the constituent sound of the phrase corresponding to the pronunciation number selection button N1 is “480”, and the maximum value of the gate time of the constituent sound of the phrase corresponding to the number of sound generation selection buttons N2, N3, N4 is , “240”, “160”, and “120”, respectively.

  At the stage where the number of pronunciations in the phrase is determined by pressing any one of the pronunciation number selection buttons N1 to N4, the values of the velocity data VDm and the gate time data GD are set to the maximum values. The user can change the values of velocity data VDm and gate time data GD to arbitrary values.

  Before describing the operation for setting the velocity data VDm and the gate time data GD, the graph window GW provided below the sounding number selection buttons N1 to N4 and the bar selection buttons MS1 to MS4 will be described.

  In the graph window GW, a graph representing the sound generation start timing, sound generation stop timing, and intensity of each component sound is displayed. This graph is a bar graph in which the horizontal axis direction is the elapsed time from the start of performance of the phrase and the vertical axis direction is the magnitude of the velocity data VDm. That is, each component sound is displayed as a long bar in the vertical direction, the height of the bar corresponds to the value of the velocity data VDm, and the width of the bar corresponds to the value of the gate time data GD. To do. The left end position of the bar corresponds to the sound generation start timing, and the right end position corresponds to the sound generation stop timing. As described above, since the sounding number selection buttons N1 to N4 correspond to the number of sounding times per measure, the number of bars displayed on the graph window GW differs depending on the pressed sounding number selection button. That is, a number of bars corresponding to the selected number of pronunciations are displayed in the graph window GW. For example, when the sounding number selection button N1 is pressed, four bars are displayed at equal intervals, and when the sounding number selection button N2 is pressed, eight bars are displayed at equal intervals. Note that the color of the bar corresponding to the beginning of each of the first beat, the second beat, the third beat, and the fourth beat is different from the colors of the other bars. FIG. 3 shows an example in which eight bars are displayed in a state in which the pronunciation number selection button N2 is pressed and a phrase to be pronounced eight times in one measure is selected.

  Next, an operation for changing the velocity data VDm will be described. As shown in FIG. 6, when one point in the operation area on the graph window GW on the touch panel 14 is touched with a finger, a pen or the like, the value of velocity data VDm corresponding to the coordinate in the horizontal axis direction of the touch position is A value corresponding to the coordinate of the touch position in the vertical axis direction is set. Then, as shown by a broken line in FIG. 6, when the finger, pen, or the like is moved to the left or right while one point in the operation area is touched with a finger, pen, etc., each bar is displayed on the locus of the touch position. The values of the velocity data VDm are changed so that the heights are equal. In the edit mode, when the performance mode of the selected performance button is the sequence mode, the sound source device 20 is controlled to repeatedly perform the performance pattern of the performance button. As a result, the user can adjust the value of the velocity data VDm while listening to the musical sound generated from the sound source device 20.

  Next, an operation for changing the gate time data GD will be described. As shown in FIG. 7, the value of the gate time data GD can be reduced by a pinch-in operation in which two points in the operation area are touched and the lateral distance between the two points is reduced. Further, the value of the gate time data GD can be increased by a pinch-out operation that increases the lateral distance between the two points. In this case, as in the case of changing the velocity data VDm, the user can adjust the value of the gate time data GD while listening to the musical sound generated from the sound source device 20.

  As shown in FIG. 8, the settings of the performance buttons P1 to P16 are stored in the ROM 17c (for example, flash memory) as a performance button set including these as a set. The ROM 17c can store a plurality of performance button sets. A performance button set number n (n = 1, 2,...) And a performance button set name SN are assigned to the performance button set. That is, the performance button set information Sn (n = 1, 2,...) Representing the content of each performance button set is the performance button set name SN and the performance button information B1 to B16 representing the settings of the performance buttons P1 to P16, respectively. It is composed of Each performance button information includes a performance button name BN, musical tone information M1 to M5, and performance pattern information PD (see FIG. 5).

  A completion button DN is arranged at the upper right end of the editing window EW. “Done” is displayed at the center of the completion button DN. When the completion button DN is pressed, the performance button setting contents are stored, the editing of the performance button setting is terminated, and the basic image is displayed again. In addition, a discard button CL is arranged at the upper left corner of the editing window EW. “Clear” is displayed in the center of the discard button CL. When the discard button CL is pressed, the editing of the performance button setting is discarded and the basic image is displayed again.

  Returning to the description of the basic image (see FIG. 2) again. A performance button set selection button SB is arranged at the upper end of the basic image. On the performance button set selection button SB, a performance button set number n and a performance button set name SN are displayed. When the performance button set selection button SB is pressed, the performance button set name SN of each performance button set stored in the ROM 17c is displayed in a list form below the performance button set selection button SB. When one of the performance button set names SN is selected, the performance button information B1 to B16 of the selected performance button set is read, and the performance buttons are read based on the read performance button information B1 to B16. The settings of P1 to P16 are updated. An increment button SINC is arranged on the right side of the performance button set selection button SB, and a decrement button SDEC is arranged on the left side of the performance button set selection button SB. “+” Is displayed on the increment button SINC, and “−” is displayed on the decrement button SDEC. When the increment button SINC is pressed, the selected performance button set number n is increased by one, and when the decrement button SDEC is pressed, the selected performance button set number n is decreased by one.

  Further, a tempo setting button TB is arranged on the right side of the performance button set selection button SB. “TAP” is displayed on the tempo setting button TB. By repeatedly pressing the tempo setting button TB a plurality of times, the tempo of the performance pattern is set using the repetition speed (number of operations per unit time). The current tempo value is displayed to the right of the tempo setting button TB.

  A transpose button TRB is arranged on the right side of the tempo button TB. The transpose button TRB is a button for transposing by simultaneously changing the pitches assigned to the 16 performance buttons constituting the performance button set in units of semitones. The transpose button TRB includes an increment button TINC and a decrement button TDEC for changing the transposition amount. “+” Is displayed on the increment button TINC, and “−” is displayed on the decrement button TDEC. A number representing the current transposition amount is displayed between the increment button TINC and the decrement button TDEC. For example, when the transposition amount display is “+0”, musical tone information of pitches respectively assigned to the performance buttons constituting the performance button set is transmitted to the sound source device 20 in accordance with the operation of the performance buttons. Also, for example, when the transposition amount display is “+1”, musical tone information having a pitch that is a semitone higher than the pitch assigned to each of the performance buttons constituting the performance button set is generated according to the operation of the performance button. Transmitted to the device 20. Further, for example, when the transposition amount display is “−1”, musical tone information having a pitch lower by a semitone than the pitches respectively assigned to the performance buttons constituting the performance button set is displayed in accordance with the operation of the performance button. It is transmitted to the sound source device 20. When the increment button TINC is pressed, the transposition amount increases by one, and when the decrement button TDEC is pressed, the transposition amount decreases by one.

  Next, the sound source control program will be described with reference to FIG. When starting execution of the sound source control program in step S10, the CPU 17a initializes various data in step S11. For example, the gate time data GD of the performance pattern information PD is initialized to “480” which is the maximum value, and the velocity data VDm is initialized to “1” which is the maximum value. Further, an end instruction flag indicating whether or not to end the sound source control program is stored in the RAM 17d, and the CPU 17a initializes the end instruction flag to “execute”.

  Next, the CPU 17a displays a basic image on the display unit 12 in step S12. In step S13, the CPU 17a detects an operation by the performer and determines a process to be executed next.

  In step S13, when an operation related to any one of the performance buttons P1 to P16 is detected, the CPU 17a determines whether the current operation mode is the performance mode or the edit mode in step S14. In the edit mode, the CPU 17a displays an edit window EW for editing the performance button settings detected in step S13 in step S15, and proceeds to step S22 described later. On the other hand, if it is the performance mode, it is further determined in step S16 whether the performance mode of the detected performance button is the normal mode or the sequence mode.

  When the current mode is the normal mode, in step S17, the CPU 17a executes a single tone generation process for generating a tone corresponding to the pressed performance button once. That is, when it is detected that the performance button has been pressed, the musical tone information assigned to the detected performance button is transmitted once to the sound source device 20 together with the note-on information, and the process proceeds to step S22 described later. When it is detected that the performance button has been released, the musical tone information is transmitted once to the sound source device 20 together with the note-off information, and the process proceeds to step S22 described later.

  On the other hand, when the current mode is the sequence mode, the CPU 17a executes a pattern performance process for repeatedly performing the performance pattern corresponding to the detected performance button in step S18. That is, when it is detected that the performance button has been turned on, execution of the pattern performance process is started. When it is detected that the performance button is held in the ON state, the sound generation start timing and the sound generation stop timing of the constituent sounds of the phrase are calculated based on the sound generation frequency data ND, the gate time data GD and the tempo, and the timer 17b. The musical tone information of the constituent sounds in which the current time measured by using and the calculated sounding start timing or sounding stop timing coincide with each other is supplied to the sound source device 20 together with the note-on information or the note-off information. Proceed. As described above, the velocity value in this case is a value obtained by multiplying velocity VL by velocity data VDm. If the current time does not coincide with the calculated sounding start timing or sounding stop timing, the process proceeds directly to step S22. When it is detected that the performance button has been turned off, the pattern performance process is terminated.

  Here, when the performance button Pb set to the sequence mode is pressed during the performance of the performance pattern PTa corresponding to the performance button Pa, the performance of the performance pattern PTb corresponding to the performance button Pb is started. 10 will be used for explanation. In this case, the performance of the performance pattern PTb is started in accordance with the progress of the performance pattern PTa. For example, assume that when the performance button Pb is pressed, the middle part of the second measure of the performance pattern PTa is being played. In this case, by starting the performance from the middle portion of the second measure of the performance pattern PTb, the measure lines (timing of the borders between adjacent measures) of both performance patterns after the third measure are aligned. That is, the progress of performance of both performance patterns is synchronized. Then, even if the performance button Pa is pressed again to stop the performance of the performance pattern PTa (for example, the middle part of the third measure), the performance of the performance pattern PTb is continued. In the figure, an example is shown in which a phrase is assigned to each of the first to third measures of the performance pattern PTa, and no phrase is assigned to the fourth measure. Further, an example is shown in which a phrase is not assigned to the first measure to the third measure of the performance pattern PTb, and a phrase is assigned to the fourth measure. As shown in the figure, when it is detected that the performance button Pc set in the normal mode is operated, the performance button Pc is independent of the performance timing of the performance pattern PTa and the performance pattern PTb. The single sound generation process is executed at the timing when the operation is detected.

  When it is detected in step S13 that the edit button ED has been pressed, the CPU 17a sets the operation mode to the edit mode in step S19. Further, when it is detected in step S13 that the inside of the editing window EW has been operated, the CPU 17a performs the performance selected in accordance with the operation in step S20 as described with reference to FIG. The button setting is changed, and the process proceeds to step S22.

  If another operation is detected in step S13, the CPU 17a executes a process corresponding to the operation in step S21. For example, when it is detected that the performance button set selection button SB is pressed, the CPU 17a switches the performance button set as described above, and when it is detected that the tempo setting button TB is pressed, the CPU 17a As described above, the tempo of the performance pattern in the sequence mode is changed, and the process proceeds to step S22.

  If it is detected that the home button has been pressed, the CPU 17a sets the end instruction flag to “end”, and the process proceeds to step S22. When the home button has not been pressed, the end instruction flag is not operated (that is, “execution” remains), and the process proceeds to step S22. In step S22, the CPU 17a determines whether or not there is an instruction to end the sound source control program. That is, if the end instruction flag is “end”, the process proceeds to step S23, and the sound source control program is ended in step S23. On the other hand, if the end instruction flag is “execute”, the CPU 17a advances the process to step S13, and thereafter repeats the above-described process.

  In the sound source control device configured as described above, a phrase of one bar is set for each performance button, and a bar that plays the set phrase is selected from the first bar to the fourth bar, and four bars are selected. The performance pattern was set. Each phrase has a simple configuration in which a musical tone having a pitch assigned to a performance button is generated at equal time intervals a selected number of times. Therefore, phrases and performance patterns can be easily set, and the configuration of the user interface used for setting them can be simplified. The performance based on the performance pattern set as described above is relatively simple, so each performance button is assigned to a performance pattern, and the combination of performance patterns to be performed simultaneously is changed one after another. Suitable for playing.

  In the edit mode, the velocity data VDm and the gate time data GD are graphed and displayed on the graph window GW, and the values of the velocity data VDm and the gate time data GD are changed according to the touch operation on the graph window GW. I made it. Specifically, the height of the bar representing the velocity data VDm is changed so as to be aligned with the locus of the touch position of the finger, pen, or the like. Further, the gate time data GD is reduced according to the pinch-in operation, and the gate time data GD is increased according to the pinch-out operation. In this way, since the movement of the touch position is associated with the way of changing the data, it can be operated intuitively.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

  For example, when each performance button is set to the sequence mode, the performance button itself is provided with a display indicating the measure to which the phrase assigned to the phrase selected using the measure selection buttons MS1 to MS4 in the edit window EW of the performance button is assigned. May be. For example, as shown in FIG. 11, selection bar displays BW1 to BW4 corresponding to the four bars constituting the performance pattern may be provided on the performance button name BN. And the display mode of selection bar display BW1-BW4 should just differ in the bar which allocates a phrase, and the bar which does not allocate a phrase. FIG. 11 shows that phrases are assigned to the first bar to the third bar, and no phrase is assigned to the fourth bar.

  Further, the display mode of the selected bar display may be changed as the performance progresses. For example, at the beginning of each measure being played, the selected measure may be displayed brighter than usual. Also, at the beginning of the first beat, the display color at other beats may be different, or the brightness may be highlighted. According to this, since the assignment state of the phrase to the performance button and the progress of the performance can be recognized just by looking at the performance button, the operability when performing using a plurality of buttons can be improved. it can.

  Further, for example, program change data defining a tone color is stored for each performance button set, and each time a performance button set is selected using the selection button SB, program change data corresponding to the selected performance button set is stored. May be transmitted to the sound source device 20. In the above embodiment, the tone color needs to be set for each MIDI channel corresponding to the performance button set by operating the tone generator 20. For example, when a performance button set that assumes that the tone setting of the tone generator 20 is a drum kit is selected, the user needs to set the tone setting of the tone generator 20 in the drum kit. . Even if the tone color setting of the tone generator 20 is different from that of the drum kit, the performance is unnatural because the performance is performed with the tone color setting. Therefore, as described above, each time a performance button set is selected, if the corresponding program change data is transmitted to the tone generator device 20, the trouble of matching the tone color setting of the tone generator device 20 with the performance button set can be saved. It can be omitted and the performance can be prevented from becoming unnatural. When a plurality of MIDI channels are used in the performance button set, program change data corresponding to each channel is stored, and each time a performance button set is selected, a program corresponding to each MIDI channel is stored. Change data may be transmitted.

  In the above embodiment, the gate time data GD is common to all the musical sounds constituting the phrase, but the gate time data may be individually stored for each musical sound. Then, the graph window GW may be touched to select one or a plurality of bars, and the value of the gate time data of the selected bar may be changed by a pinch-in operation and a pinch-out operation. In this case, for example, velocity data and gate time data may be displayed as separate graphs. For example, a line graph with the horizontal axis direction as the sound production timing, the vertical axis direction as the velocity data value, and a line graph with the horizontal axis direction as the sound generation timing and the vertical axis direction as the gate time data value Also good.

  In the above embodiment, the gate time data GD is a relative value when one beat is “480”. Instead, the gate time data GD corresponds to the maximum value of the length of each musical tone of the selected performance pattern. It may be a relative value. That is, what percentage of the maximum value may be stored as the gate time data GD.

  In the above embodiment, in the sequence mode, a value obtained by multiplying the velocity VL of the musical sound information M1 to M5 by the velocity data VDm of the performance pattern information PD is used as the velocity of the constituent sound of the set phrase. However, the velocity data VDm may represent the absolute value of the velocity of the constituent sound of the phrase. In this case, in the sequence mode, the values of the velocity VL of the musical tone information M1 to M5 respectively assigned to the performance buttons P1 to P16 are not used, but velocity data VDm constituting the performance pattern information PD is used. When a plurality of pieces of musical tone information are assigned to the performance button, the musical tone information is simultaneously transmitted to the tone generator device 20 at a timing according to the tempo setting and the performance pattern information PD. The velocity VL set as the musical sound information M1 to M5 is not used, and the velocity data VDm is used as the velocity of the constituent sound. That is, in this case, the velocities of the sounds that are simultaneously generated are common.

  In the above embodiment, the velocity data VDm and the gate time data GD of the constituent sound of the phrase can be set for each performance button. However, only one of them can be set and the other value can be a fixed value. Good. Further, the setting method of the velocity data VDm and the gate time data GD is not limited to the above operation. For example, a numeric keypad type input operator may be displayed, and a numerical value of velocity data VDm may be input for each constituent sound using the numeric keypad type input operator. The numerical value of the gate time data GD may be input using the input operator.

  In the above embodiment, when the performance button set to the sequence mode is pressed once, the performance pattern starts playing. When the performance button is released and then pressed again, the performance pattern is stopped. did. However, the performance pattern may be played while the performance button is kept pressed, and the performance pattern may be stopped when the performance button is released.

  In the above embodiment, a one-measure phrase is set for each performance button, but a longer phrase such as a two-measure phrase or a three-measure phrase is set by increasing the number of velocity data VDm. Alternatively, conversely, the number of velocity data VDm may be reduced to set a shorter phrase such as a phrase for 2 beats or a phrase for 3 beats. In the above embodiment, the number of pronunciations of the musical tone of the pitch assigned to the performance button in the phrase is any one of 4, 8, 12, and 16, but the number of pronunciations is less. May be more or more. For example, the number of pronunciations of the musical sound in a phrase may be 1 or 32. The performance pattern is not limited to four bars, and the number of bars may be increased or decreased.

  In the above embodiment, the phrase is configured to repeat the musical tone having the pitch assigned to the performance button. However, the present invention is not limited to this, and a melody or chord input using a keyboard button KB or a keyboard device connected via the communication interface circuit 18 may be assigned to a performance button as a phrase.

  Moreover, in the said embodiment, although the sound source device 20 is provided in the exterior of the portable information terminal, you may be incorporated in the portable information terminal. The sound source control program is not limited to the portable information terminal, but may be applied to an electronic musical instrument, a personal computer, or the like, and these devices may be operated as a sound source control device. Various buttons such as the performance buttons P1 to P16 and the tempo setting button TB may be configured using a tact switch, a variable resistor, or the like.
