[First embodiment]
A. Configuration FIG. 1 is a block diagram showing the overall configuration of a musical sound generator 100 according to a first embodiment of the present invention. In this figure, the CPU 10 controls each part of the apparatus in accordance with an event supplied from the operation unit 14, the pad 16 and the keyboard 17, and the detailed processing operation related to the gist of the present invention will be described later. To do. The ROM 11 includes a program area and a data area. The program area of the ROM 11 stores various program data including a main routine, a switch process, and a pad process, which will be described later, executed by the CPU 10.

  Although not shown, accompaniment patterns (1) to (N) associated with accompaniment pattern numbers are stored in the data area of the ROM 11. One accompaniment pattern is composed of pattern data representing the pitches and pronunciation timings of various accompaniment sounds (tone color parts) that form a music piece for a predetermined measure. The pattern data includes, for example, a normal pattern representing a music piece of a predetermined measure, an intro pattern corresponding to the introduction part of the normal pattern, a fill-in pattern inserted in the middle of the normal pattern, and an ending pattern added to the end part of the normal pattern It is formed.

The RAM 12 includes a work area WE and a sampling waveform data area SWDE as shown in FIG. Various register / flag data used for processing of the CPU 10 are temporarily stored in the work area WE of the RAM 12, while being input to the sampling waveform data area SWDE by a sampling input unit 15 described later under the control of the CPU 10. Sampling waveform data is stored. The display unit 13 includes, for example, an LCD panel (not shown) and a display driver (not shown) that drives the LCD panel in response to a display control signal supplied from the CPU 10. The device setting status and operation status to be set are displayed on the screen.

The operation unit 14 includes various switches and operation keys arranged on a console panel (not shown), and generates an event corresponding to the operation. This event is captured by the CPU 10 key scan. As switch types arranged on the operation unit 14, in addition to a power switch (not shown), an accompaniment pattern selection switch for selecting an accompaniment pattern used for automatic accompaniment, a start / stop switch for instructing start / stop of automatic accompaniment, There are a pad assign switch for selecting a timbre part to be assigned to a pad, a sampling switch for instructing the start of sampling, and the like. The operation keys disposed on the operation unit 14 include, for example, a cursor key and an enter key that are used together when the pad assign switch is operated.

  The sampling input unit 15 amplifies the audio signal input via the microphone or the audio signal supplied from the audio input terminal to a certain level in accordance with a sampling start instruction from the CPU 10, and then performs A / A at a predetermined sampling frequency. Sampling waveform data obtained by D conversion is output. The sampling waveform data output from the sampling input unit 15 is stored in the sampling waveform data area SWDE of the RAM 12 described above under the control of the CPU 10.

The pad 16 has a pad switch arranged on the pad surface, and generates an ON / OFF event indicating an on / off operation of the pad switch in accordance with a user's pad operation. In addition to the pad operation, the pad 16 is subjected to a pad long pressing operation for pressing the pad surface and maintaining the pad switch in the on state. The purpose of this pad long press operation will be described later. The keyboard 17 generates performance information including a key-on / key-off event, a key number, a velocity, and the like in response to a key press / release operation.

The sound source 18 is configured by a well-known waveform memory reading method including waveform data of various timbres, and includes a plurality of sound generation channels capable of simultaneous sound generation. The tone generator 18 generates a tone output corresponding to a tone command generated by the CPU 10 based on the performance information output from the keyboard 17, or receives sampling waveform data from the sampling waveform data area SWDE of the RAM 12 according to the pad operation of the pad 16. Read to generate sampling sound output. In the sound source 18, when the pad 16 is pressed for a long time while the automatic accompaniment is in progress, a sampling sound output is generated in synchronization with the sound of the accompaniment sound of a specific tone color assigned to the pad. The sound system 19 D / A converts the musical sound output output from the sound source 18 and then amplifies the sound output from the speaker.

B. Operation Next, the operation of the musical tone generator 100 having the above-described configuration will be described with reference to FIGS. 3 is a flowchart showing the operation of the main routine executed by the CPU 10, FIG. 4 is a flowchart showing the operation of the switch process called from the main routine, and FIG. 5 is the operation of the accompaniment pattern selection switch process called from the switch process. 6 is a flowchart showing the operation of the start / stop switch process called from the switch process, FIG. 7 is a flowchart showing the operation of the pad assign switch process called from the switch process, and FIG. 8 is a call from the switch process. FIG. 9 is a flowchart showing the pad processing operation called from the main routine.

(1) Main Routine Operating Unit When the power supply is turned on, the CPU 10 executes the main routine shown in FIG. 3 and proceeds to step SA1 to store various registers and flags stored in the work area WE of the RAM 12. Initialize to reset or set the initial value. In step SA1, the sound source 18 is instructed to initialize various registers and flags.

When the initialization is completed, the CPU 10 proceeds to step SA2 and executes switch processing corresponding to a switch event generated by operating various switches (accompaniment pattern selection switch, start / stop switch, pad assign switch, pad switch, and sampling switch). . Details of the switch processing will be described later. Next, in step SA3, it is determined whether or not the flag SSF is “1”, that is, whether or not the sampling start is instructed by the operation of the sampling switch.

If the flag SSF is “0”, that is, if sampling start is not instructed, the determination result in step SA3 is “NO”, and the process proceeds to step SA5 described later, but the flag SSF is “1”. In step SA3, the determination result is “YES”, and the flow advances to step SA4 to execute sampling processing.

In this sampling process, the sampling input unit 15 is instructed to start sampling, and in response to this, the sampling waveform data output from the sampling input unit 15 is stored in the sampling waveform data area SWDE of the RAM 12. Then, when the writing to the sampling waveform data area SWDE is completed, the sampling input unit 15 is instructed to stop sampling, and the flag SSF is reset to zero to finish the processing.

Next, in step SA5, a keyboard process for generating a musical sound command corresponding to the performance information output from the keyboard 17 and supplying it to the tone generator 18 is executed. Subsequently, in step SA6, it is determined whether or not the flag STF is “1”, that is, whether the start of the automatic accompaniment is instructed by operating the start / stop switch (automatic accompaniment is in progress). If the flag STF is “0”, that is, if the automatic accompaniment is stopped, the determination result in step SA6 is “NO” and the process proceeds to step SA8 described later, but the automatic accompaniment is in progress (the flag STF is “1”). ")", The determination result in step SA6 is "YES", and the process proceeds to step SA7 to execute automatic accompaniment processing for reproducing the user-selected accompaniment pattern.

  In step SA8, as will be described later, when a pad operation is performed while automatic accompaniment is stopped, the sound source 18 is instructed to reproduce the sampled sound for each operation, while the pad long press operation is performed while automatic accompaniment is in progress. If so, pad processing is executed to instruct the sound source 18 to play back the sampled sound at the tone pitch in accordance with the tone of the specific tone part selected by the pad assign switch operation. For example, other processes such as displaying the device setting state and the operation state on the screen are executed. Thereafter, steps SA2 to SA9 are repeatedly executed until the apparatus power is turned off.

(2) Operation of Switch Processing Next, the operation of switch processing will be described with reference to FIG. When the switch process is executed through step SA2 (see FIG. 3) of the main routine described above, the CPU 10 performs accompaniment pattern selection switch process (step SB1), start / stop switch process (step SB2) shown in FIG. Pad assignment switch processing (step SB3), pad switch processing (step SB4), and other switch processing (step SB5) are sequentially executed. Hereinafter, the operation for each of these switch processes will be described.

Note that the other switch processing in step SB5 includes sampling switch processing. In the sampling switch process, although not shown, the flag SSF described above is set to “1” in accordance with the operation of the sampling switch to indicate a state instructing the start of sampling.

(A) Accompaniment pattern selection switch processing operation When this processing is executed via step SB1 (see FIG. 4) of the switch processing, the CPU 10 proceeds to step SC1 shown in FIG. That is, it is determined whether or not automatic accompaniment is stopped. If the automatic accompaniment in which the flag STF is “1” is in progress, the determination result is “NO”, and the present process ends. That is, when the automatic accompaniment is in progress, the operation of the accompaniment pattern selection switch is invalidated.

  On the other hand, if the automatic accompaniment is stopped, the determination result in step SC1 is “YES”, and the process proceeds to step SC2 to determine whether or not the accompaniment pattern selection switch has been turned on. If the operation is not turned on, the determination result is “NO”, and the present process is completed. However, if the operation is turned on, the determination result is “YES”, and the process proceeds to step SC3, and the accompaniment pattern selection switch is turned on. The selected accompaniment pattern number is stored in the register ACPN, and this process is finished.

(B) Operation of start / stop switch process When this process is executed through step SB2 (see FIG. 4) of the switch process, the CPU 10 advances the process to step SD1 shown in FIG. It is determined whether or not an ON operation has been performed. If the start / stop switch is not turned on, the determination result is “NO”, and this process is completed.

On the other hand, when the ON operation is performed, the determination result in step SD1 is “YES”, the process proceeds to step SD2, and the flag STF is inverted. The flag STF indicates automatic accompaniment start (accompaniment in progress) when “1”, and automatic accompaniment stop when “0”. That is, every time the start / stop switch is turned on, it is a so-called toggle switch that sets a flag so as to indicate the start or stop of the alternate, so that the value of the flag STF is inverted every time it is turned on.

In step SD3, it is determined whether the inverted flag STF is “1”. Here, when the inverted flag STF is “0”, that is, when the start / stop switch is turned on, the judgment result is “NO”, and the process proceeds to step SC4. The sound source 18 is instructed to mute all the accompanying accompaniment sounds, and this process is finished.

On the other hand, when the inverted start flag STF is “1”, that is, when a transition is made to the state instructing the start of automatic accompaniment, the determination result in step SD3 is “YES”, the process proceeds to step SD5, and the accompaniment pattern selection described above is performed. The accompaniment start setting for performing address setting for reading pattern data from the head of the accompaniment pattern selected by the operation of the switch is executed, and this processing is completed.

(C) Operation of the pad assign switch process When this process is executed via step SB3 (see FIG. 4) of the switch process, the CPU 10 advances the process to step SE1 shown in FIG. Judgment is made. If the pad assign switch is not operated, the determination result is “NO”, and the present process is terminated. However, if it is operated, the determination result is “YES”, and the process proceeds to step SE2. In step SE2, timbre parts (accompaniment sound types) constituting the accompaniment pattern specified by the accompaniment pattern number stored in the register ACPN are read from the ROM 11 and displayed in a list on the display unit 13.

Next, in step SE3, a specific tone color part to be assigned to the pad 16 is selected from the tone color parts displayed in the list. Specifically, a desired timbre part is designated from among the timbre parts displayed in a list on the screen of the display unit 13 by operating the cursor key, and the specified specific timbre part is selected and set by operating the enter key. This process is finished.

(D) Operation of pad switch process When this process is executed via step SB4 (see FIG. 4) of the switch process, the CPU 10 proceeds to step SF1 shown in FIG. 8 to determine whether there is a pad switch event. To do. If there is no pad switch event, the determination result is “NO”, and the present process is finished. However, if a pad switch event is generated by the operation of the pad 16, the determination result is “YES”, and the process proceeds to Step SF2.

  In step SF2, it is determined whether or not the generated pad switch event is an ON event. If the event is an ON event, the determination result is “YES”, the process proceeds to step SF 3, the ON flag ONF is set to “1”, and this process is terminated. On the other hand, if the generated pad switch event is an OFF event, the determination result in step SF2 is “NO”, the process proceeds to step SF4, the ON flag ONF is reset to zero, and the present process ends.

(3) Pad Processing Operation Next, the pad processing operation will be described with reference to FIG. When the pad process is executed via step SA8 (see FIG. 3) of the main routine described above, the CPU 10 proceeds to step SG1 shown in FIG. 9, and determines whether or not the flag STF is “1”, that is, automatic accompaniment. Determine if it is in progress. Hereinafter, the explanation of the operation will be divided into a case where the automatic accompaniment is stopped and a case where the automatic accompaniment is in progress.

<When automatic accompaniment is stopped>
If the automatic accompaniment is stopped (the flag STF is “0”), the determination result in step SG1 is “NO”, and the process proceeds to step SG2. In step SG2, it is determined whether or not the ON flag ONF is “1”. If the pad 16 generates an ON event in response to the pad operation, the determination result is “YES”, and the process proceeds to step SG3 to instruct the sound source 18 to generate a sampling sound. As a result, the sound source 18 reads the sampling waveform data from the sampling waveform data area SWDE of the RAM 12 and reproduces the sampling sound. As described above, when the automatic accompaniment is stopped, if a pad operation for hitting the pad surface is applied to the pad 16 as in percussion instrument performance, the sampling sound is reproduced for each pad operation.

<When automatic accompaniment is in progress>
On the other hand, if automatic accompaniment is in progress (flag STF is “1”), the determination result in step SG1 is “YES”, the process proceeds to step SG4, and it is determined whether or not the ON flag ONF is “1”. Here, it is assumed that a pad long pressing operation for pressing the pad surface and maintaining the pad switch in the ON state is applied to the pad 16. Then, since the ON flag ONF is maintained at “1” while the pad long press operation is performed by the pad switch process (see FIG. 8) described above, the determination result is “YES”, and the process proceeds to Step SG5.

In step SG5, it is determined whether or not a specific timbre part is assigned to the corresponding pad. Here, if the specific part is not assigned, the determination result is “NO”, and the process proceeds to Step SG3. In this case, the sampling sound is reproduced every time the pad is operated, as in the case where the automatic accompaniment is stopped. On the other hand, if the specific timbre part is assigned to the corresponding pad, the determination result is “YES”, and the flow proceeds to step SG6.

In step SG6, whether or not the MIDI channel to which the specific tone part is assigned is being turned on, that is, whether or not the accompaniment tone of the specific tone selected in the above-described pad assignment switch process (see FIG. 7) is being generated. Judging. If not sounding accompaniment sound of a specific tone color, the judgment result is "NO", but the process is ended, if sounding, the judgment result is "YES", the flow proceeds to step SG 7, accompaniment sounding Instructs the sound source to produce a sampling sound at the pitch of the sound. As a result, the sound source 18 reads sampling waveform data from the sampling waveform data area SWDE of the RAM 12 at a reading speed corresponding to the pitch of the accompaniment sound that is being generated, and generates a sampling sound output. When the specific tone color part is an accompaniment sound such as “drum”, the sampling waveform data is reproduced with the original pitch at the time of sampling.

  As described above, in the first embodiment, the pad 16 is operated for a long time during the automatic accompaniment in a state where the specific timbre part is selected from the various timbre parts automatically accompaniment to the pad 16. In response to the sound of the accompaniment sound of the selected specific timbre part, the sampled sound is reproduced at the sound pitch. For example, when the shout “high / high” uttered by the user is stored in the sampling waveform data area SWDE of the RAM 12 as sampling waveform data, if the pad is pressed for a while during automatic accompaniment, the user's sound is played in accordance with the sound of the specific tone part. Since the shout “Hi-Hi” is played back as a sampled sound, it is possible to embody a rhythm performance that plays back the sampled sound in synchronization with the accompaniment sound of a specific tone that is specified in advance, among the accompaniment sounds of various tones that are automatically accompanied I can do it. This also has the effect that even users who are unfamiliar with musical instrument performance can easily enjoy rhythm performance.

  In the first embodiment, the pad 16 needs to be pressed for a long time during the automatic accompaniment in order to reproduce the sampled sound at the sounding pitch according to the sounding of the accompaniment sound of the selected specific timbre part. However, the present invention is not limited to this. For example, you may comprise so that it may be performed by operation of a setting switch etc. different from the pad 16. FIG.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. The configuration of the second embodiment is different from that of the first embodiment described above in that a pressure sensor (for example, a piezoelectric element) is provided on the pad surface of the pad 16 to detect the operation pressure when the pad is pressed and detected. The pad data PD representing the pressure is generated. Hereinafter, as operations of the second embodiment having such a configuration, operations of pad assignment switch processing and pad processing different from those of the first embodiment will be described.

(1) Operation of Pad Assign Switch Process FIG. 10 is a flowchart showing the operation of the pad assign switch process according to the second embodiment. As in the first embodiment described above, when this process is executed via the switch process step SB3 (see FIG. 4), the CPU 10 advances the process to step SH1 shown in FIG. Judgment is made. If the pad assign switch is not operated, the determination result is “NO”, and the present process is finished. However, if it is operated, the determination result is “YES”, and the process proceeds to step SH2.

In step SH2, timbre parts constituting the accompaniment pattern specified by the value of the register ACPN (accompaniment pattern number) are read from the ROM 11 and displayed in a list on the display unit 13. Subsequently, in step SH3, the first timbre part to be assigned to the pad 16 is selected from the list-displayed timbre parts when the pad data PD is less than a predetermined value. Next, in step SH4, the second timbre part to be assigned to the pad 16 is selected from the list-displayed timbre parts when the pad data PD is equal to or greater than a predetermined value, and this processing is completed.

(2) Pad Processing Operation FIG. 11 is a flowchart showing the pad processing operation according to the second embodiment. As in the first embodiment described above, when pad processing is executed via step SA8 (see FIG. 3) of the main routine, the CPU 10 proceeds to step SJ1 shown in FIG. 11, and the flag STF is “1”. Whether or not automatic accompaniment is in progress. Hereinafter, the explanation of the operation will be divided into a case where the automatic accompaniment is stopped and a case where the automatic accompaniment is in progress.

<When automatic accompaniment is stopped>
If the automatic accompaniment is stopped (the flag STF is “0”), the determination result in step SJ1 is “NO”, and the process proceeds to step SJ2. In step SJ2, it is determined whether or not the ON flag ONF is “1”. If the pad 16 generates an ON event in response to the pad operation, the determination result is “YES”, and the process proceeds to step SJ3 to instruct the sound source 18 to generate a sampling sound. As a result, the sound source 18 reads the sampling waveform data from the sampling waveform data area SWDE of the RAM 12 and reproduces the sampling sound. As described above, when the automatic accompaniment is stopped, if a pad operation for hitting the pad surface is applied to the pad 16 as in percussion instrument performance, the sampling sound is reproduced for each pad operation.

<When automatic accompaniment is in progress>
On the other hand, if automatic accompaniment is in progress (flag STF is “1”), the determination result in step SJ1 is “YES”, the process proceeds to step SJ4, and it is determined whether the on flag ONF is “1”. Here, it is assumed that a pad long pressing operation for pressing the pad surface and maintaining the pad switch in the ON state is applied to the pad 16. Then, since the ON flag ONF is maintained at “1” while the pad is pressed by the above-described pad switch process (see FIG. 8), the determination result is “YES”, and the flow proceeds to Step SJ5.

In step SJ5, it is determined whether or not the value of the pad data PD generated in response to the pad long press operation is greater than or equal to a predetermined value. If the value of the pad data PD is less than the predetermined value, the determination result is “NO”, and the flow proceeds to step SJ6. In step SJ6, it is determined whether or not the MIDI channel to which the first timbre part is assigned is being turned on, that is, whether or not the accompaniment sound of the first timbre part is being produced. If the sound is not being generated, the determination result is “NO”, and the present process is terminated. If the sound is being sounded, the determination result is “YES”, and the process proceeds to Step SJ8 described later.

On the other hand, if the value of the pad data PD is equal to or larger than the predetermined value, the determination result in step SJ5 is “NO”, and the process proceeds to step SJ7, and the MIDI channel to which the second timbre part is assigned is in the note-on state. Whether or not the accompaniment sound of the second timbre part is sounding. If the sound is not being generated, the determination result is “NO”, and the present process ends. If the sound is being sounded, the determination result is “YES”, and the process proceeds to step SJ8. In step SJ8, the sound source is instructed to generate a sampling sound at the pitch of the accompaniment sound that is being generated.

As a result, the sound source 18 reads the sampling waveform data from the sampling waveform data area SWDE of the RAM 12 at a reading speed corresponding to the pitch of the accompaniment sound being sounded, and reproduces the sampling sound. When the first timbre part or the second timbre part is an accompaniment sound such as “drum”, the sampling waveform data is reproduced with the original pitch at the time of sampling.

  As described above, in the second embodiment, among the various timbre parts that are automatically accompanied, when the pad data PD representing the operation pressure at the time of the pad long press operation is less than the predetermined value, the first timbre part is displayed as the pad. If the data PD is greater than or equal to a predetermined value, a second timbre part is assigned, and if the pad 16 is pressed for a long time during automatic accompaniment, the pad data PD generated by the long press operation is less than the predetermined value. If there is, the sampled sound is reproduced with the sound pitch of the first timbre part, and if the pad data PD is greater than or equal to a predetermined value, the sound is sounded with the sound of the second timbre part. Since the sampled sound is reproduced at the pitch, it is possible to realize a rhythm performance in which the sampled sound is reproduced in synchronization with an accompaniment sound of a specific tone color among accompaniment sounds of various timbres automatically accompanied. Also, since the sampled sound can be reproduced in synchronization with the timbre accompaniment sound corresponding to the pressing state when the pad is pressed long, even a user unfamiliar with musical instrument performance can easily enjoy the rhythm performance. Also has the effect of.
