According to the eighth aspect of the invention, every time a waveform generation instruction is received, a waveform number corresponding to the note number included in the waveform generation instruction is selected, and the waveform corresponding to the selected waveform number is read out to produce a human voice. When a reset operation is performed while a modulation waveform of 1 is being generated, reading is restarted from the top address of the waveform of the currently selected waveform number, so for example 1 corresponding to the waveform number selected by a certain note number If the waveform of a human voice that represents a sentence is generated with two waveforms, the modulation waveform of the voice can be generated by reading the sentence from the beginning in response to a reset operation, thus generating various musical sounds.

A key scaling value is stored in the register KeyScaling. The key scaling characteristic of the key scaling table KST stored in the ROM 6 is selected by this key scaling value. The key scaling value is set according to the operation of the setting mode switch.

  In the register WaveNum, the waveform number of the currently selected modulation waveform (described later) is temporarily stored. The number of the newly selected modulation waveform is temporarily stored in the register NewWaveNum. In the register WaveAddress, a read address of waveform data specified by the waveform number stored in the register WaveNum is temporarily stored. The register WaveIdx temporarily stores an index value that specifies the steps (array elements) of the register WaveSeqOrder [0] to [15].

  The register ResetCnt is a reset counter that counts a waveform reset time (register WaveResetTime) by a timer process described later that is executed at regular intervals. The register NoteCnt is a counter that counts the number of note-on events (or the number of key presses) in the carrier part. The reset flag Reset is “1” when the reset foot switch 3 generates a waveform reset signal or when there is no new note-on event until the waveform reset time elapses after all keys are released, and “0” otherwise. Flag. The hold flag Hold is “1” when the hold foot switch 2 generates a hold signal instructing prohibition of waveform reset, and is “0” otherwise.

(3) Configuration of Sound Source 12 Next, the configuration of the sound source 12 will be described with reference to FIGS. As described above, the sound source 12 changes the waveform generation mode according to the waveform reset mode value supplied from the CPU 9. Specifically, when the waveform reset mode values are “0”, “1”, and “2”, a musical tone waveform is generated by the first configuration shown in FIG. If the waveform reset mode value is “3”, a tone waveform is generated by the second configuration shown in FIG. Hereinafter, the first and second configurations will be described.

(A) First Configuration of Sound Source 12 In FIG. 6, reference numerals 12a-1 to 12a-n denote waveform generators provided for the respective sound generation channels. Each waveform generator is supplied from the waveform ROM 13 (or waveform RAM 14) according to the parameters supplied from the CPU 9. Read waveform data and generate waveform. When the waveform reset mode values are “0”, “1” and “2”, the waveform generator 12a-1 is assigned to the modulator part, and the other waveform generators 12a-2 to 12a-n are assigned to the carrier part. It is done. An adder 12b adds the outputs of the waveform generators 12a-2 to 12a-n assigned to the carrier part and outputs the result.
The output of the waveform generator 12a-1 assigned to the modulator part is supplied to the modulator input of the DSP 15 as a modulated waveform. On the other hand, the output of the adder 12b is supplied to the carrier input of the DSP 15 as a modulated waveform. In the sound source 12 having the first configuration, as will be described later, the output of the DSP 15 is directly output to the D / A converter 16 at the next stage as a musical sound waveform.

(B) Second Configuration of Sound Source 12 Next, a second configuration of the sound source 12 will be described with reference to FIG. When the waveform reset mode value is “3”, the sound source 12 includes parts P1 to P16 corresponding to the MIDI channel. Any one of these parts P1 to P16 is set as a modulator part and a carrier part. The modulator part is designated by the modulator part number stored in the register ModulatorPart. Similarly, the carrier part is designated by the carrier part number stored in the above-described register CarrierPart. In the example shown in FIG. 7, part P1 is set as a modulator part, and part P2 is set as a carrier part.

A waveform generator 12a and an adder 12b are dynamically assigned to each part P1 to P16 by an assigner (not shown). In the example shown in FIG. 7, the waveform generator 12a-P1 is assigned to the part P1 serving as the modulator part, and the plurality of waveform generators 12a-P2 and these waveform generators 12a-P2 are allocated to the part P2 serving as the carrier part. An adder 12b-P2 for adding and outputting the outputs is assigned.
A switch 12c switches the output path of each of the parts P1 to P16. The switch 12c is configured to switch the modulation waveform output from the modulator part to the terminal MODULATOR from the carrier part according to the switching control signal generated by the CPU 9 based on the modulator part number and carrier part number stored in the registers ModulatorPart and CarrierPart respectively. The path is switched so that the output modulated waveform is supplied to the terminal CARRIER and the waveform output of the other parts is supplied to the mixer 12d at the next stage.

  In the example shown in FIG. 7, the modulation waveform generated by the part P1 is switched to the terminal MODUTOR, the modulated waveform generated by the part P2 is switched to the terminal CARRIER, and the waveform outputs of the parts P3 to P16 are switched to the mixer 12d. . The Kimisa 12d outputs a musical sound waveform obtained by mixing the waveform output supplied via the switch 12c and the output of the DSP 15 to the D / A converter 16 at the next stage.

(4) Configuration of DSP 15 Next, the configuration of the DSP 15 will be described with reference to FIG. The DSP 15 includes an analysis unit 150, a synthesis unit 151, and an adder 152. The analysis unit 150 includes band pass filters (hereinafter referred to as BPF) 150a-1 to 150a-n and envelope detectors (hereinafter referred to as ENV) 150b-1 to 150b-n. Each of the BPFs 150a-1 to 150a-n has a pass frequency band corresponding to the formant frequency of the human voice, and extracts a formant component of the modulation waveform (modulator part output) supplied from the sound source 12. ENVs 150b-1 to 150b-n are composed of an absolute value circuit including a rectifier and a smoothing circuit including an LPF, and detect an envelope level of a formant component extracted by the BPFs 150a-1 to 150a-n.

  The combining unit 151 includes BPFs 151a-1 to 151a-n and multipliers 151b-1 to 151b-n. The BPFs 151a-1 to 151a-n have the same pass frequency band as the analysis units 150BPF 150a-1 to 150a-n, and the modulated waveform (carrier part output) supplied from the sound source 12 is converted into n pass frequency bands. Split filter. The multipliers 151b-1 to 151b-n multiply the outputs of the BPFs 151a-1 to 151a-n by the envelope levels of the respective formant components detected by the ENVs 150b-1 to 150b-n. The adder 152 adds and synthesizes the outputs of the multipliers 151b-1 to 151b-n and outputs the result to the sound source 12 side.

When the waveform reset mode values are “0”, “1”, and “2”, as described above, the sound source 12 has the first configuration shown in FIG. It passes through and is input to the D / A converter 16 in the next stage. On the other hand, when the waveform reset mode value is “3”, the sound source 12 has the second configuration illustrated in FIG. 7, and the output of the adder 152 is input to the Kimisa 12 d of the sound source 12.
According to such a configuration, when a modulation waveform of human voice sound (modulator part output) and a modulated waveform of musical instrument sound (carrier part output) are input from the sound source 12, the modulated waveform becomes a formant component of the modulation waveform. As a result of the modulation, a musical instrument sound like a human voice is generated.

The CPU 9 interrupts and executes timer processing at regular intervals in the course of executing the main routine described above. When the interrupt execution timing is reached, the timer process is started and the process proceeds to step SB1 of FIG. 10 to determine whether the value of the register ResetCnt is “0”, that is, whether the waveform reset time is being measured. If the value of the register ResetCnt is “0”, the waveform reset time is not counted, so the determination result is “YES”, and this processing is completed without doing anything.
On the other hand, if the value of the register ResetCnt is not “0”, the waveform reset time is counted, so the determination result is “NO”, and the process proceeds to the next step SB2.

In step SB2, the value of the register ResetCnt is incremented and incremented, and in the subsequent step SB3, it is determined whether or not the value of the incremented register ResetCnt has reached the waveform reset time stored in the register WaveResetTime.

If the waveform reset time is in this state, whether or not the waveform reset time is reached by incrementing the value of the register ResetCnt. to decide. When the waveform reset time is reached, the reset flag Reset is set to “1” to set a state for instructing waveform reset.

In step SC9, the waveform number for each of the velocity values “0” to “127” is set in the registers VelMap [0] to [127], and this processing is completed. The waveform numbers set in the registers VelMap [0] to [127] are referred to under the velocity mode of the waveform selection mode value “2”.

<Press the numeric keypad “4”>
When the numeric key “4” is pressed, the process proceeds to step SC10. In step SC10, the waveform selection mode values (“0”, “1”, and “2”) for selecting the waveform to be read are set in the register WaveSelectMode, and this processing is completed.

<Press the numeric keypad “5”>
When the numeric key “5” is pressed, the process proceeds to step SC11. In step SC11, the waveform reset mode values (“0”, “1”, “2”, and “3”) that specify the waveform reset method are set in the register WaveRestMode, and this processing is completed. The contents of the waveform reset mode values “0” to “3” are as described above.

<Press the numeric keypad “6”>

(4) Keyboard Processing Operation Next, the keyboard processing operation will be described with reference to FIG. When this process is executed through step SA3 (see FIG. 9) of the main routine described above, the CPU 9 advances the process to step SD1 in FIG. 12, and the key-on / key-off generated in response to the key release operation of the keyboard 1 is performed. Determine if there is an event. If no key operation is performed and a key-on / key-off event is not detected by the switch scanner 5, the determination result is “NO”, and this processing is once completed. On the other hand, when a key-on / key-off event is detected, the determination result in step SD1 is “YES”, the process proceeds to step SD2, and note-on / off processing is executed.

(5) Operation of Note On / Off Process Next, the operation of the note on / off process will be described with reference to FIG. When this processing is executed via step SD2 (see FIG. 12) of the keyboard processing or step SM5 (see FIG. 19) of MIDI processing which will be described later, the CPU 9 proceeds to step SE1 in FIG. 13 and performs part check processing. .
In the part check process, as described later, flags ModNote and CarNote indicating whether or not a modulated waveform is generated in the modulator part and whether or not a modulated waveform is generated in the carrier part are set according to the set waveform reset mode value. When the carrier part generates a modulated waveform based on the flag setting, it counts the number of on events according to the input note-on event, or decrements the number of on-events according to the input note-off event. When all notes are turned off, the timer processing is instructed to start measuring the waveform reset time.

  When such part check processing is completed, the CPU 9 proceeds to step SE2 and determines whether or not the input event is a note-on event. If it is a note-off event, the determination result is “NO”, and the process proceeds to step SE13, where a mute process is performed to instruct the sound source 12 to mute the musical tone of the pitch corresponding to the note number included in the note-off event. Thereafter, the process proceeds to Step SE8 described later.

On the other hand, if the input event is a note-on event, the determination result in step SE2 is “YES”, and the flow proceeds to step SE3. In steps SE3 to SE7, a waveform readout mode corresponding to the waveform selection mode value stored in the register WaveSelectMode is designated by user setting.
Hereinafter, a waveform readout mode instructed for each of “sequential mode”, “key mapping mode”, and “velocity mode” selected by waveform selection mode values “0” to “2” will be described.

(A) In the case of sequential mode (waveform selection mode value “0”) When the sequential mode is set, the process proceeds to step SE4, and the waveform readout form corresponding to the waveform reset mode values “0” to “3” is selected. Executes the sequential mode processing to be set. The specific processing operation of the sequential mode processing will be described in detail later. The content is summarized as follows.

When the waveform reset mode value is “0”, the waveform is reset so that the waveform is read from the start address of the waveform designated by the next waveform number in response to the note-on event.
In the case of the waveform reset mode value “1”, in the hold state, the waveform is reset so as to read from the start address of the waveform specified by the next waveform number in response to the note-on event, while an explicit reset operation ( When the reset foot switch 3 is turned on, or when there is no new note-on event until the waveform reset time elapses after all notes are off), the waveform is reset so that it is read from the head address of the head waveform.
In the case of the waveform reset mode value “2”, a modulation waveform is generated in accordance with the performance operation of the lower key range, and the waveform reset method at that time is the same as the waveform reset mode value “1”.
In the case of the shape reset mode value “3”, a modulation waveform is generated in the modulator part among a plurality of parts included in the sound source 12, and the waveform resetting method at that time is the same as the waveform reset mode value “1”.

(B) In case of key mapping mode (waveform selection mode value “1”) When the key mapping mode is set, the process proceeds to step SE5. In step SE5, in accordance with the note number included in the note-on event, the corresponding waveform number is read from the registers KeyMap [0] to [127] and stored in the register NewWaveNum. Then, the process proceeds to step SE6, and the map mode process for setting the waveform readout mode corresponding to the waveform reset mode values “0” to “3” is executed. The specific processing operation of this map mode processing will be described in detail later, and the contents are summarized as follows.

In the case of the waveform reset mode value “0”, the waveform is reset so as to read from the head address of the currently selected waveform in response to the note-on event.
When the waveform reset mode value is “1”, if the modulation waveform to be read is changed or an explicit reset operation is performed even if the read modulation waveform is not changed, the start address of the modulation waveform selected in accordance with the current note-on event If the modulation waveform to be read does not change, or if the hold state or explicit reset operation is not performed, the waveform is read again from the waveform read address that was read last by the sound of the previous note-on event. To.
In the case of the waveform reset mode value “2”, a modulation waveform is generated according to the performance operation of the lower key range, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. Become.
Further, in the case of the waveform reset mode value “3”, a modulation waveform is generated in the modulator part among a plurality of parts included in the sound source 12, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. become.

(C) In the velocity mode (waveform selection mode value “2”) When the velocity mode is set, the process proceeds to step SE7. In step SE7, the corresponding waveform number is read from the registers VelMap [0] to [127] according to the velocity value included in the note-on event, and is stored in the register NewWaveNum. Then, in the same manner as in the above (b) key mapping mode, the map mode processing for setting the waveform readout mode corresponding to the waveform reset mode values “0” to “3” is executed.

As described above, after setting the waveform readout mode corresponding to the waveform selection mode values “0” to “2” and the waveform reset mode values “0” to “3”, the CPU 9 performs the modulators in steps SE8 to SE10. The sound generation process related to the part is performed in steps SE11 to SE12.
That is, in step SE8, it is determined whether or not the flag ModNote set by the part check process in step SE1 is “1”, that is, whether or not a modulation waveform is generated from the modulator part according to the note-on event. If the modulation waveform is not generated from the modulator part, the determination result is “NO”, and the flow proceeds to step SE11 described later.

On the other hand, if the modulation waveform is generated from the modulator part, the determination result in step SE8 is “YES”, and the flow proceeds to step SE9. In step SE9, the key scaling characteristic corresponding to the key scaling value stored in the register KeyScaling is selected from the key scaling table KST stored in the ROM 6, and the note number included in the note-on event is generated according to the selected key scaling characteristic. It is converted to a waveform pitch (cent value) that represents the pitch of the musical tone to be played.
Subsequently, in step SE10, the sound source 12 is instructed to read out the modulated waveform in the waveform reading form set by the sequential mode process (step SE4) or the map mode process (step SE6) based on the waveform selection mode value and the waveform reset mode value. At the same time, a modulator part sound generation process is executed to instruct the sound source 12 to sound the modulation waveform at the pitch of the waveform pitch obtained in step SE9.

Next, in step SE11, it is determined whether or not the flag CarNote set by the part check process in step SE1 is “1”, that is, whether a modulated waveform is generated from the carrier part according to the note-on event. If the modulated waveform is not generated from the carrier part, the determination result is “NO” and the process is completed.
On the other hand, if the modulated waveform is generated from the carrier part, the determination result is “YES”, and the flow proceeds to step SE12. In step SE12, the sound source 12 is instructed to read out the modulated waveform in the waveform reading form set by the sequential mode process (step SE4) or the map mode process (step SE6) based on the waveform selection mode value and the waveform reset mode value. Then, after executing the carrier part sound generation process for instructing the sound source 12 to generate the modulated waveform at a pitch corresponding to the note number included in the note-on event, the present process is terminated.

(6) Part Check Processing Operation Next, the part check processing operation will be described with reference to FIG. When this process is executed via step SE1 of the note on / off process, the CPU 9 proceeds to step SF1 in FIG. 14 and determines the waveform reset mode value stored in the register WaveResetMode. In steps SF2 to SF10, a flag ModNote and a flag CarNote are set according to the determined waveform reset mode value.
Here, the flag ModNote is a flag indicating whether or not the modulator part generates a modulation waveform. When the value is “0”, it indicates that it does not occur, and when it is “1”, it indicates that it occurs. The flag CarNote is a flag indicating whether or not the carrier part generates a modulated waveform. When the value is “0”, it indicates that the carrier part does not occur, and when it is “1”, it indicates that it occurs. Hereinafter, the flag setting operation performed in steps SF2 to SF10 will be described separately for the waveform reset mode value “0” or “1”, “2”, and “3”.

(A) When the waveform reset mode value is “0” or “1” If the waveform reset mode value is “0” or “1”, the process proceeds to step SF2, and “1” is set to the flag ModNote to set the modulator part. Indicates that a modulated waveform is generated, and the flag CarNote is set to “1” to indicate that the carrier part generates a modulated waveform.

(B) When the waveform reset mode value is “2” If the waveform reset mode value is “2”, the process proceeds to step SF3 and the note number included in the input event (on / off event or MIDI input event corresponding to the key operation). Is smaller than the split point stored in the register SplitPoint, that is, it is an input event corresponding to the lower key area. If the input event corresponds to the lower key range, the determination result is “YES”, the process proceeds to step SF4, and the flag ModNote is set to “1” to indicate that the modulator part generates a modulation waveform. The flag CarNote is set to “0” to indicate that the carrier part does not generate a modulated waveform.
On the other hand, if the input event corresponds to the upper key range, the determination result in step SF3 is “NO”, the process proceeds to step SF5, the flag ModNote is set to “0”, and the modulator part does not generate a modulation waveform. In addition, the flag CarNote is set to “1” to indicate that the carrier part generates a modulated waveform.

(C) When the waveform reset mode value is “3” If the waveform reset mode value is “3”, the process proceeds to step SF6, and the channel number to which the input event is assigned, the modulator part number stored in the register ModulatorPart, To determine if they match. If they match, the determination result is “YES”, and the process proceeds to step SF7, where “1” is set in the flag ModNote to indicate that the modulator part generates a modulation waveform, and “0” is set in the flag CarNote. This indicates that the carrier part does not generate a modulated waveform.

On the other hand, if they do not match, the determination result in step SF6 is “NO”, and the flow proceeds to step SF8. In step SF8, it is determined whether or not the channel to which the input event is assigned is a carrier part. If it is a carrier part, the determination result is “YES”, the process proceeds to step SF9, “0” is set to the flag ModNote to indicate that the modulator part does not generate a modulation waveform, and “1” is set to the flag CarNote. "Indicates that the carrier part generates a modulated waveform.
On the other hand, if the channel to which the input event is assigned is another part other than the modulator part and the carrier part, the determination result in step SF8 is “NO”, the process proceeds to step SF10, and both the flags ModNote and CarNote are “0”. "Is set.

As described above, when the flag ModNote and the flag CarNote are set according to the waveform reset mode value, the CPU 9 advances the process to step SF11 to determine whether or not the flag CarNote is “1”. If the flag CarNote is set to “0” and the carrier part does not generate a modulated waveform, the determination result is “NO” and the process is completed.
On the other hand, if the flag CarNote is set to “1” and the carrier part generates a modulated waveform, the determination result is “YES”, and the flow proceeds to the next step SF12. In step SF12, it is determined whether or not the input event is a note-on event.

If it is an input note-on event, the determination result is “YES”, the process proceeds to step SF13, the counter NoteCnt for counting the number of key presses in the carrier part is incremented and stepped, and the waveform reset time is counted. The value of the counter ResetCnt is reset to zero to complete this processing.
On the other hand, if the input event is a note-off event, the determination result in step SF12 is “NO”, and the flow proceeds to step SF14. In step SF14, the counter NoteCnt is decremented, and in the subsequent step SF15, it is determined whether or not the value of the decremented counter NoteCnt is “0”, that is, whether or not all keys are released.

  If all keys are not released, the determination result is “NO”, and this process is completed. However, if all keys are released, the determination result is “YES”, and the process proceeds to step SF16 where the counter ResetCnt is set to “1”. ”Is set to finish the process. When “1” is set in the counter ResetCnt due to the all key release state, the above-described timer processing (see FIG. 10) starts to measure the waveform reset time.

  As described above, in the part check process, the flag ModNote indicating whether a modulated waveform is generated from the modulator part or whether a modulated waveform is generated from the carrier part according to the waveform reset mode value set by the user. When CarNote is set and a modulated waveform is generated from the carrier part, the counter NoteCnt is incremented in response to a note-on event (or key-on event), while on the other hand, in response to a note-off event (or key-off event) When the counter NoteCnt is decremented and all notes are released (all keys are released), the timer processing is instructed to start counting the waveform reset time.

(7) Operation of Sequential Mode Processing Next, the operation of the sequential mode processing will be described with reference to FIG. When this process is executed via step SE4 (see FIG. 13) of the note-on / off process, the CPU 9 proceeds to step SG1 in FIG. 15, and determines the waveform reset mode value stored in the register WaveResetMode. Next, in steps SG2 to SG5, a waveform readout attribute is set according to the determined waveform reset mode value. Hereinafter, the operation for setting the waveform readout attribute will be described for each of the waveform reset mode values “0” to “3”.

(A) In the case of the waveform reset mode value “0” In this case, the process proceeds to step SG2, and the index value stored in the register WaveIdx is incremented and updated, while the register WaveSeqOrder [WaveIdx] is updated according to the updated index value. ] Is read out and stored in the register WaveNum. In step SG2, “0” is stored in the register WaveAddress so that the waveform data of the waveform number stored in the register WaveNum is read from the head, and this processing is completed.
As described above, in the waveform reset mode value “0”, the waveform is reset so that the waveform is read from the head address of the waveform designated by the next waveform number in response to the note-on event.

(B) Case of Waveform Reset Mode Value “1” In this case, the sequential mode waveform setting process is executed via step SG3, and the process proceeds to step SH1 in FIG. In step SH1, it is determined whether or not the hold flag Hold is “0”, that is, whether or not the hold foot switch 2 is turned on. If the hold foot switch 2 is turned on to be in the hold state (hold flag Hold is “1”), the determination result is “NO”, the process proceeds to step SH4, and the index value stored in the register WaveIdx is incremented. Update it.

Thereafter, the process proceeds to step SH5, and in accordance with the updated index value, the waveform number is read from the register WaveSeqOrder [WaveIdx] and stored in the register WaveNum, and the waveform data of the waveform number stored in the register WaveNum is read from the head. Accordingly, “0” is stored in the register WaveAddress to complete this processing.
As described above, when the waveform reset mode value “1” is set to the hold state, the waveform is reset so as to read from the head address of the waveform designated by the next waveform number in response to the note-on event.

  On the other hand, if the hold foot switch 2 is not turned on, the determination result in step SH1 is “YES”, and the process proceeds to step SH2. In step SH2, it is determined whether or not the reset flag Reset is “1”, that is, the reset foot switch 3 is turned on, or there is no new note-on event until the waveform reset time elapses from all note-off. . If it does not correspond to any state, the determination result is “NO”. In this case, as in the hold state described above, steps SH4 to SH5 are executed, and the next waveform number is designated according to the note-on event. Reset the waveform to read from the top address of the waveform.

On the other hand, if the reset foot switch 3 is turned on, or if there is no new note-on event until the waveform reset time has elapsed since all-note-off, the determination result in step SH2 is “YES”, and step SH3. Then, the reset flag Reset is set to “0” and the index value stored in the register WaveIdx is reset to zero. Then, the process proceeds to step SH5, and the read attribute is set so as to read from the head address of the head waveform.
Thus, in the waveform reset mode value “1”, there is an explicit reset operation (when the reset foot switch 3 is turned on, or when there is no new note-on event until the waveform reset time elapses from all note-off. The waveform is reset to read from the top address of the top waveform.

(C) In the case of the waveform reset mode value “2” In this case, the process proceeds to step SG4 in FIG. 15, and the note number included in the note-on event is smaller than the split point stored in the register SplitPoint, that is, in the lower key range. Determine if it is a corresponding note-on event. If it is a note-on event corresponding to the lower key range, the determination result is “YES”, the process proceeds to step SG3, and the above-described sequential mode waveform setting process (see FIG. 16) is executed, and then this process is completed. .

On the other hand, if the event is a note-on event corresponding to the upper key range, the determination result in step SG4 is “NO”, and the performance is performed in the upper key range, so the register WaveNum and the register WaveAddress are not changed. Finish.
Thus, with the waveform reset mode value “2”, a modulation waveform is generated in accordance with the performance operation of the lower key range, and the waveform resetting method at that time is the waveform reset mode value “ 1 ".

(D) In the case of the waveform reset mode value “3” In this case, the process proceeds to step SG5, where it is determined whether the channel number to which the note-on event is assigned matches the modulator part number stored in the register ModulePart. If they match, the determination result is “YES”, and the sequential mode waveform setting process (see FIG. 16) is executed via step SG3, and then this process is completed.
On the other hand, if they do not match, the determination result in step SG5 is “NO”, and the performance is other than the modulator part. Therefore, the register WaveNum and the register WaveAddress are not changed, and the process is finished.
In this way, with the waveform reset mode value “3”, a modulation waveform is generated by the modulator part among the plurality of parts included in the sound source 12, and the waveform reset method at that time is the waveform reset mode described in the above section (b). This is the same as the value “1”.

As described above, according to the sequential mode process, when the waveform reset mode value is “0”, the waveform is reset so that the waveform is read from the top address of the waveform designated by the next waveform number in response to the note-on event.
In the case of the waveform reset mode value “1”, if it is in the hold state, the waveform is reset so as to read from the start address of the waveform specified by the next waveform number in response to the note-on event. When there is an operation (when the reset foot switch 3 is turned on or when there is no new note-on event until the waveform reset time elapses after all notes are off), the waveform is reset so that it is read from the top address of the top waveform. To do.
In the case of the waveform reset mode value “2”, a modulation waveform is generated according to the performance operation of the lower key range, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. Become.
Further, in the case of the waveform reset mode value “3”, a modulation waveform is generated in the modulator part among a plurality of parts included in the sound source 12, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. become.

(8) Map Mode Processing Operation Next, map mode processing operation will be described with reference to FIG. When this process is executed through step SE6 (see FIG. 13) of the note on / off process, the CPU 9 proceeds to step SK1 in FIG. 17 and determines the waveform reset mode value stored in the register WaveResetMode. Next, in steps SK2 to SK5, a waveform readout attribute is set according to the determined waveform reset mode value. Hereinafter, the operation for setting the waveform readout attribute will be described for each of the waveform reset mode values “0” to “3”.

(A) Case of Waveform Reset Mode Value “0” In this case, the process proceeds to step SK2, and the waveform number stored in the register NewWaveNum is stored in the register WaveNum. The waveform number stored in the register NewWaveNum is read from the register KeyMap [note number] (or register VelMap [velocity value]) in step SE5 (or step SE7) of the note on / off process shown in FIG. It is a number representing the modulation waveform to be selected. In step SK2, “0” is stored in the register WaveAddress so that the waveform data of the waveform number stored in the register WaveNum is read from the head, and this processing is completed.
As described above, in the waveform reset mode value “0”, the waveform is reset so as to read from the head address of the currently selected waveform in response to the note-on event.

(B) Case of Waveform Reset Mode Value “1” In this case, the map mode waveform setting process is executed via step SK3, and the process proceeds to step SL1 in FIG. In step SL1, it is determined whether or not the waveform number stored in the register NewWaveNum matches the waveform number stored in the register WaveNum, that is, whether or not the read waveform is changed.
When the read waveform is changed, the determination result is “NO”, the process proceeds to step SL2, the waveform number stored in the register NewWaveNum is stored in the register WaveNum, and the waveform data of the waveform number stored in the register WaveNum is stored from the top. To read, “0” is stored in the register WaveAddress to complete this processing. As a result, when the readout waveform changes, the waveform is reset so as to read from the start address of the modulation waveform selected according to the current note-on event.

On the other hand, if the modulation waveform selected corresponding to the current note-on event does not change with the modulation waveform selected corresponding to the previous note-on event, the determination result in step SL1 is “YES”. The process proceeds to step SL3. In step SL3, it is determined whether or not the hold flag Hold is “0”, that is, whether or not the hold foot switch 2 is not turned on. If it is in the hold state (hold flag Hold is “1”), the determination result is “NO”, and this process is completed.
Therefore, if the read waveform does not change under the hold state, the waveform is read again from the waveform read address read last by the sound generation of the previous note-on event.

  On the other hand, if not in the hold state, the determination result in step SL3 is “YES”, and the flow proceeds to step SL4. In step SL4, the reset flag Reset is “1”, that is, an explicit reset operation (a state in which the reset foot switch 3 is turned on, or a state in which there is no new note-on event until the waveform reset time elapses after all notes are off). Determine whether or not If there is no explicit reset operation, the determination result is “NO”, and this process is completed. Therefore, if an explicit reset operation is not performed and the read waveform does not change, the waveform is read again from the waveform read address read last by the sound generation of the previous note-on event.

  On the other hand, when an explicit reset operation is performed, the determination result in step SL4 is “YES”, the process proceeds to step SL5, the reset flag Reset is set to “0”, and the register WaveAddress is set to “0”. To complete this process. Therefore, if there is an explicit reset operation in a state where the modulation waveform is not changed, the waveform is reset so as to read from the start address of the modulation waveform selected according to the current note-on event.

  In this way, with the waveform reset mode value “1”, the modulation selected in response to the current note-on event when the modulation waveform to be read changes or when there is an explicit reset operation even if the modulation waveform to be read does not change. Reset the waveform to read from the top address of the waveform. On the other hand, when the read modulation waveform is not changed, if the hold state or the explicit reset operation is not performed, the waveform is read again from the waveform read address read last by the sound generation of the previous note-on event.

(C) In the case of the waveform reset mode value “2” In this case, the process proceeds to step SK4 in FIG. 17, and the note number included in the note-on event is smaller than the split point stored in the register SplitPoint, that is, in the lower key range. Determine if it is a corresponding on-event. If it is a note-on event corresponding to the lower key range, the determination result is “YES”, the process proceeds to step SK3, and after executing the above-described map mode waveform setting process (see FIG. 18), this process is completed. .
On the other hand, if it is a note-on event corresponding to the upper key range, the determination result in step SK4 is “NO”, and the performance is performed in the upper key range, so the register WaveNum and the register WaveAddress are not changed. Finish.
Thus, with the waveform reset mode value “2”, a modulation waveform is generated in accordance with the performance operation of the lower key range, and the waveform resetting method at that time is the waveform reset mode value “ 1 ".

(D) When the Waveform Reset Mode Value is “3” In this case, the process proceeds to step SK5, and it is determined whether the channel number to which the note-on event is assigned matches the modulator part number stored in the register ModulatorPart. If they match, the determination result is “YES”, and the above-described map mode waveform setting process (see FIG. 18) is executed via step SK3, and then this process is completed.
On the other hand, if they do not match, the determination result in step SK5 is “NO”, and the performance is other than the modulator part. Therefore, the register WaveNum and the register WaveAddress are not changed, and the process is finished.
In this way, with the waveform reset mode value “3”, a modulation waveform is generated by the modulator part among the plurality of parts included in the sound source 12, and the waveform reset method at that time is the waveform reset mode described in the above section (b). This is the same as the value “1”.

As described above, according to the map mode process, in the case of the waveform reset mode value “0”, the waveform is reset so as to read from the head address of the currently selected waveform in response to the note-on event.
In the case of the waveform reset mode value “1”, if the modulation waveform to be read is changed or an explicit reset operation is performed even if the read modulation waveform is not changed, it is selected according to the current note-on event (or key-on event). The waveform is reset so that it is read from the start address of the modulation waveform. If the read modulation waveform is not changed, or if the hold state or the explicit reset operation is not performed, the waveform is read again from the waveform read address read last by the sound generation of the previous note-on event.
In the case of the waveform reset mode value “2”, a modulation waveform is generated according to the performance operation of the lower key range, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. Become.
Further, in the case of the waveform reset mode value “3”, a modulation waveform is generated in the modulator part among a plurality of parts included in the sound source 12, and the waveform resetting method at that time is the same as the waveform reset mode value “1”. become.

(9) Operations of MIDI processing Next, operations of the MIDI processing will be described with reference to FIG. When this process is executed through step SA4 (see FIG. 9) of the main routine described above, the CPU 9 advances the process to step SM1 in FIG. 19, and first determines whether or not there is a MIDI input. If there is no MIDI input, this processing is once completed and the processing is returned to the main routine. If there is a MIDI input, it is determined whether the event is a system exclusive message (see FIG. 3) for waveform data transfer, a note-on / note-off event, or another event. If another event has been input, the process proceeds to step SM6, and after other event processing is performed, the process returns to step SM1.

If the above-described system exclusive message (see FIG. 3) is input, the process proceeds to step SM2, the system exclusive message is fetched into a reception buffer (not shown), and the waveform data (WADEDATA) is taken out from the fetched message. ) Are extracted and stored in the waveform RAM 14.
If a note-on / note-off event is input, the process proceeds to step SM3 to determine whether the waveform reset mode value is set to any one of “0”, “1”, and “2”.

  If the waveform reset mode value is “3”, the determination result is “NO”, and the process proceeds to Step SM5 described later. If the waveform reset mode value is set to any one of “0”, “1”, and “2”, the determination result is “YES”, the process proceeds to the next step SM4, and the MIDI channel of the note on / note off event It is determined whether the number matches the carrier part number stored in the register CarrierPart. If they match, the determination result is “YES”, the above-described note on / off process (see FIG. 13) is executed via step SM5, and then the process returns to step SM1. On the other hand, if they do not match, the determination result is “NO”, and the process returns to step SM1.

As described above, in the MIDI processing, when the waveform data is transferred and input by the system exclusive message, the waveform data (WAVDATA) included in the message is extracted and stored in the waveform RAM 14.
When the waveform reset mode value is set to “0”, “1”, or “2”, the note on / off process is performed only when the MIDI channel number of the input note on / note off event corresponds to the carrier part. When the waveform reset mode value is set to “3”, the note on / off process is executed for the part corresponding to the MIDI channel number of the input note on / note off event. It has become.

As described above, in this embodiment, the sound source 12 generates the modulation waveform of the human voice sound and the modulated waveform of the instrument sound, and the DSP 15 covers the instrument sound according to the formant component extracted from the modulation waveform of the human voice sound. Since vocoder processing that modulates the modulation waveform is performed to create a musical instrument sound like a human voice, unlike the conventional configuration in which vocoder processing is performed by inputting an audio signal from the outside, vocoder performance is always performed. It can be reproduced in the same way.
In other words, waveform data obtained by sampling a human voice is stored in the waveform RAM 14, and the sound source 12 reproduces the waveform data to generate a modulation waveform of the human voice sound. This results in a reproducible vocoder performance. . In addition, such a configuration eliminates the need for means for capturing an input signal from the outside, so that an effect that can contribute to a reduction in product cost can be obtained as compared with a configuration in which an audio signal is input from the outside and vocoder processing is performed.

In the present embodiment, as described above, various waveform readout modes are set according to the waveform selection mode values “0” to “2” and the waveform reset mode values “0” to “3”, so that various musical sounds can be set. The generation form can be realized.
For example, when the waveform reset mode value is set to “0” under the sequential mode (waveform selection mode value “0”), for example, lyrics corresponding to each note constituting the song are stored in the waveform RAM 14 as individual waveform data. In addition, when the reading order is registered in the register WaveSeqOrder, the lyrics of the song are reproduced as a modulated waveform according to the performance operation, and vocoder processing is performed based on this, resulting in a musical sound as if a person is singing Can be made.

  In addition, under the key mapping mode (waveform selection mode value “1”) or the velocity mode (waveform selection mode value “2”), the modulation waveform differs depending on the note number or velocity value of the key that was pressed. The user can specify the timing of modulating the modulated waveform of the instrument sound with the modulation waveform of the human voice, and how to reset the modulation waveform according to the operation of the hold foot switch 2 and the reset foot switch 3. It is possible to generate a variety of modulation waveforms such as specifying, so that various musical sound generation forms can be realized.

  In the above-described embodiment, the sound source 12 generates a modulation waveform of the human voice corresponding to the performance information and a modulated waveform of the instrument sound, and the DSP 15 applies the instrument sound according to the formant component of the modulation waveform of the human voice. Although the vocoder performance sound is generated by modulating the modulation waveform, the present invention is not limited to this, and the CPU 9 may execute the processing of the sound source 12 and the DSP 15. In this case, the CPU 9 generates a waveform generation processing program for generating a modulation waveform of a human voice corresponding to input performance information and a modulated waveform of a musical instrument sound, and a formant of the modulation waveform of the human voice generated by the waveform generation processing. A vocoder processing program for generating a vocoder performance sound by modulating the modulated waveform of the musical instrument sound according to the component is executed.
