If the OMF is "1", it is determined whether or not the play flag PF is "1" (step C2). . If the PF is "1", it is determined whether or not the melody is started (step C).
3). If the melody has started, the pitch data of the melody is set in the register RATE (step C).
4). Next, a voice pronunciation process is executed (step C).
5). Then, the process returns to the main flow.

If the PF is "0" in step C2, or if the melody is not started in step C3, this flow is terminated and the flow returns to the main flow. If the OMF is "0" in step C1, the sound mode is not set, and the normal tone generation process corresponding to the keyboard operation is performed (step C6). Then, this flow ends and the process returns to the main flow.

FIG. 6 shows the CPU 21 on the personal computer 2 side.
5 is a flowchart of a command reception process of FIG. This command receiving process is executed when an interrupt for command reception via the serial interface 23 occurs during execution of a main flow (not shown) of the CPU 21.
It is determined whether or not the received command is a music reproduction start command (step D1). When this command is received, the two pointers m and n provided in the RAM 25 are set to "1" (step D1). D2). Then, this flow ends and the process returns to the main flow.

If the command received in step D1 is not a music reproduction start command, it is determined whether or not an audio data request command has been received (step D).
3). When this command is received, a character data display process for displaying the character data of the lyrics corresponding to the voice data on the display unit 27 is performed (step D4). next,
An audio data transmission process is executed (step D5). When the transmission is completed, this flow is terminated and the process returns to the main flow.

If it is determined in step D3 that the received command is not a voice data request command, it is determined whether a music reproduction end command has been received (step D3).
6). When this command is received, the character display on the display unit 27 is cleared (step D7), and this flow is ended to return to the main flow. If the received command is not one of the music reproduction start command, the audio data transfer request command, and the music reproduction end command, but is another command, another process corresponding to the received command is performed (step D8). Ends the flow and returns to the main flow.

FIG. 7 shows a table of voice data of lyrics of "robot" in the first embodiment. Audio data corresponding to each ASCII code is stored in the HD or CD serving as a waveform memory. This audio data is composed of a header section and a PCM data section. The header part includes the following ASCII codes “RO”, “BO”
− ”And information on PCM data corresponding to“ TO ”. Here, “BO−” corresponds to the prompt sound “B”, and the normal voice “BO” and the prompt sound addition mark “−”
It is composed of However, in the waveform memory, P
The CM data is not stored, and the PCM data of the ordinary voice is corrected based on the prompting mark "-". m and n correspond to the addresses of audio data (header data and PCM data) in the waveform memory, m indicates each audio data, and n indicates each data in the audio data specified by m.

Next, the audio data transmission processing in step D5 of FIG. 6 in the first embodiment will be described. In FIG. 8, it is determined whether or not the sound data requested to be transferred from the electronic musical instrument 1 this time is different from the sound data transmitted last time (step E1). If the sound data is different, the sound data corresponding to the address of the waveform memory designated by the pointers m and n is read and written to the transmission data buffer of the RAM 25 (step E2). Initially, the value set in step D2 in FIG. 6 is (m = n = “1”), so the data corresponding to “n = 1” in the table area corresponding to “m = 1” in FIG. The audio data is read from the waveform memory and written to the transmission data buffer in order from the unit (in this case, 1 byte unit). Each time writing is performed, n is incremented (step E3), and it is determined whether or not there is a prompt sound addition mark (step E4). When there is no prompt sound addition mark, it is determined whether or not the pointer n has exceeded the maximum value of the currently designated pointer m (step E6).

If n is less than the maximum value, step E
In step 2, the audio data is read from the address of the waveform memory designated by m and n and written to the transmission data buffer. If there is a prompt sound addition mark in step E4, the last address is written to the second address of the transmission data buffer (step E5). Then, in the processing of steps E2 to E6, the audio data in the waveform memory is sequentially written into the transmission data buffer while incrementing n, and n is incremented in step E6.
Exceeds the maximum value, the voice data is transmitted to the electronic musical instrument (step E7).

Then, m is incremented to designate the next audio data, and n is set to "1" to set m.
The first data of the audio data specified by is specified (step E8). Next, the character data is supplied to the VDP 26 (step E9), and this flow ends and returns to the main flow. If the current voice data is the same as the previously transmitted voice data in step E1, the voice data reuse command is transmitted without transmitting the voice data corresponding to the transfer request command (step E10). Since the data of the voice data reuse command is much smaller than the voice data including PCM data, the transmission time is much shorter. After transmitting the command, this flow ends and the flow returns to the main flow.

FIG. 9 shows a configuration of a buffer in which audio data corresponding to "BO-" in FIG. 7, that is, audio data of a prompt sound is written in a transmission data buffer. The header section includes an area for storing the number of PCM data and an area for storing a loop start address.
Further, the PCM data part includes the twelve PCM data shown in FIG.
The area is configured to store data d1 to d12. Therefore, in this case, "12" is written in the area of the number of PCM data, and "13" which is the last address of the transmission data buffer is written in the area of the loop start address. If there is no prompt, “8” which is the head address of the loop portion is used.
Is written.

Next, a description will be given of the musical instrument side reception processing executed by the CPU 11 of the electronic musical instrument 1 in the first embodiment. FIG. 10 is a flowchart of the musical instrument side reception processing, and FIG.
15B shows registers DZ and LS corresponding to the PCM data written into the buffer 15B and the two buffers. When the buffer area 15A or 15B is designated as a read buffer, the read buffer flag RBF is set to “0” or “1”. When the buffer areas 15A and 15B are designated as write buffers, the write buffer flag WBF is set to “0” or “1”. RBF and WBF are exclusive logical values, and a buffer specified as a write buffer cannot be specified as a read buffer. Note that the musical instrument-side reception processing of FIG. 10 is executed every time there is an interruption of received data from the personal computer 2 side.

In FIG. 10, it is determined whether or not the received data is a voice data reuse command (step F).
1). If voice data is received instead of the voice data reuse command, it is determined whether or not the received data is a header part (step F2). If the received data is a header part, the received data is the first data. It is determined whether the data is present or the second received data (step F3). If the received data is the first received data, the received data is written to the data size address DZ (step F4). Then, the process returns to the main flow.

If the received data is the second received data, data obtained by subtracting the data number "2" of the header part from the received data is written into the loop start address register LS (step F5). That is, the data in the header portion of the received data is not written in the received data buffer,
Write to the predetermined register shown in FIG. Next, the value of RBF is set to WBF (step F6). That is,
The buffer previously designated as the read buffer is designated as the write buffer. Since RBF and WBF are exclusive logical values, the buffer previously designated as the write buffer is automatically designated as the read buffer. Next, the write address WAD of the buffer specified by the WBF is set to "0 (head address)" (step F7). Then, the process returns to the main flow.

If the received data is not a header in step F2, that is, if the received data is PCM data, the write address WAD "0" of the buffer designated as the write buffer in step F7.
Then, the PCM data which is the received data is written into (step F8). After writing the PCM data, it is determined whether or not the WAD has reached the last address where the last PCM data was written (in this case, a value obtained by subtracting "1" from the DZ data) (step F9). . At first WAD =
Since it is 0, it is not the last address. If it is not the last address, WAD is incremented to designate the next write address of the buffer (step F1).
0). Thereafter, this flow ends and the process returns to the main flow.

The PCM data is written to the reception data buffer every time an interruption of the reception data occurs while incrementing the WAD. If the WAD reaches the last address (DZ-1) in step F9, it means that all the PCM data requested to the personal computer 2 by the voice data transfer request command has been received. In this case, the data flag DF indicating that all the requested audio data has been received is set to "1" (step F11). Then, this flow ends and the process returns to the main flow.

FIG. 11A shows the PCM data of the lyrics written in the reception data buffer and the register DZ.
And the data of the number of PCM data written in the register LS and the data of the loop start address.
(1) In the case of ordinary voice lyrics "B" instead of a prompt,
(2) is a case of the lyric “B” of the prompting sound. In the case of the normal voice of (1), “6” is written in LS, and d7 to
The PCM data of d12 forms a loop part. On the other hand, in the case of the prompt sound of (2), "11" is written in LS, and there is no loop portion.

FIG. 12 is a flowchart of the voice sound generation process in step C5 of the music reproduction process of the first embodiment in FIG. In this process, first, it is determined whether or not the reuse flag SF is “0” (step G1). SF
Is "0", that is, if the audio data reuse command is not received from the personal computer 2, it is determined whether or not the data flag DF is "1" (step G2). DF
Is "1", the requested PCM data has all been written to the reception data buffer. Therefore, while inverting the RBF, the receiving buffer which has been in the data writing state up to that point is brought into the reading state,
The read address RAD of the received data buffer is set to “0 (first address)” (step G).
3). Next, R set in step C4 of FIG.
RAD at the read speed corresponding to the pitch data of ATE
Is read and transmitted to the sound source 16 (step G4).

Next, RAD is incremented (step G5). Then, it is determined whether the RAD is the same as the DZ data (step G6). As shown in FIG. 11, the data of DZ (the number of PCM data) is a value larger by “1” than the last address. Therefore, R
If the data of AD and DZ are not the same, the last PC
This is the case where the reading of the M data has not been completed. In this case, the process proceeds to step G4, in which the PCM data of the RAD is read out and transmitted to the sound source 16 at a reading speed corresponding to the pitch data of RATE. And d1, d
The PCM data is read out in the order of 2, d3, d4,...

At step G6, if the data of the RAD and the data of the DZ are the same, the RAD is "1" more than the last address, and the reading of the last PCM data d12 is completed. . In this case, it is determined whether or not the LS data is the same as the value obtained by subtracting “1” from the DZ data (step G7). FIG.
As is clear from FIG. 1, the LS data in the case of the normal voice shown in (1) is smaller by "6" than the DZ data.
On the other hand, the LS data in the case of the prompt sound shown in (2) is smaller by "1" than the DZ data. That is, in step G7, it is determined whether the PCM data in the reception data buffer is a normal sound or a prompt sound.

At step G7, the LS data is
If the value is not the value obtained by subtracting “1” from the data of Z, the vowel is continuously looped because it is a normal voice. Therefore, the address of the RAD is rewritten to the address of the LS (step G8), and the address of the PCM data of d7 which is the head of the loop shown in FIG. 11A is designated. Then, it is determined whether the envelope value of the envelope register ENV is “0”, that is, whether or not the sound is muted (step G9). If the ENV data is not “0”, the process proceeds to step G 4, where the head PCM data of the loop portion is read out at the RATE read speed and transmitted to the sound source 16.

By repeating the processing of steps G4 to G9, the PCM data of d7 to d12 in FIG.
PCM reading at the reading speed of E and composing vowels
The data is repeatedly sent to the sound source 16. Therefore,
The ordinary voices of “B” and “G” in the lyrics of “Robot” are pronounced. In step G9, ENV is "0"
, The data flag DF is reset to "0" (step G10). Next, the voice data transfer request command is written into the transmission data buffer (step G1).
1). Then, this flow ends and the process returns to the main flow.

In step G7, the data of LS is D
If the value is a value obtained by subtracting "1" from the data of Z, the data flag DF is reset to "0" and the process proceeds to step G1.
0), an audio data transfer request command is written to the transmission data buffer (step G11). Then, this flow ends and the process returns to the main flow. That is, in this case, since the sound is a prompt sound, the PCM data of d1 to d12 is transmitted to the sound source 16 only once, and the PCM data constituting the vowel is not repeatedly transmitted. Therefore, the voice of the prompting sound of “B” is pronounced in the lyrics of “Robot”.

If the SF is "1" at step G1, it means that the audio data reuse command has been received from the personal computer 2. In this case, RAD is set to "0" without inverting RBF (step G12). That is, the head address of the reception data buffer from which the previous reading has been completed is specified again. Then, the flow shifts to step G4, where the audio data in the reception data buffer is transmitted to the sound source 16 at the RATE reading speed.

As described above, in the first embodiment,
The personal computer 2 receives a transfer request command for requesting transmission of audio data corresponding to the lyrics from an external device (electronic musical instrument 1) that plays a melody accompanied by lyrics, and receives the transfer request command from the external device (electronic musical instrument 1). Determining means for determining whether the requested current voice data is different from or the same as the previously requested voice data; and determining that the requested current voice data is different when the determining means determines that the requested current voice data is different. And a transmitting means for transmitting a voice data reuse command to the external device when the determining means determines that they are the same.

With the above configuration, when the external device that plays the melody accompanied by the lyrics requests the transfer of the audio data corresponding to the lyrics, the personal computer 2 replaces the current audio data requested to be transferred with the previously transmitted audio data. If it is the same as above, the voice data is not transferred, and a command to reuse the previous voice data is transmitted. Therefore, when playing the melody of a song with lyrics, only the reuse command is transmitted for the previously transferred voice data, and the transfer time of the voice data of all lyrics can be reduced, so that the pronunciation of the voice of the lyrics is not delayed. Can be

In the first embodiment, the electronic musical instrument 1 transfers the voice data corresponding to the lyrics of the melody to be played to the external device (the personal computer 2) storing the voice data corresponding to the lyrics.

It has become adult.

With the above configuration, when the electronic musical instrument 1 receives a voice data reuse command from an external device (personal computer 2) storing voice data corresponding to lyrics,
The audio data previously sent to the sound source is sent again to the sound source.
Therefore, when playing a melody of a song with lyrics,
When a reuse command is received instead of voice data, there is no need to wait for the transfer of voice data, so that the pronunciation of the lyrics can be prevented from being delayed.

As a modification of the first embodiment,
When transmitting the audio data reuse command from the personal computer 2, a parameter of the number of reuses may be transmitted. In this case, when there is the same lyrics many times in succession, continuous transmission of the lyrics can be performed only by transmitting the command once, so that the pronunciation of the voice of the lyrics is not further delayed. Can be In addition, since communication traffic congestion can be avoided, communication efficiency is improved.

Next, a second embodiment of the present invention will be described. Unlike the first embodiment, the RAM 15 of the electronic musical instrument 1 according to the second embodiment is provided with eight reception data buffers. However, the CPU 11 of the electronic musical instrument 1
In the program executed by the first embodiment, the main flow and the switch processing in the main flow are the same as the flows in FIGS. 3 and 4 in the first embodiment. In the program executed by the CPU 21 of the personal computer 2,
The command receiving process and the voice data transmitting process are the same as those in the flow of FIGS. Therefore, description of these processes is omitted, and other drawings are also described.
The description of the same components as those of the first embodiment will be omitted, and the second embodiment will be described with reference to the drawings of the first embodiment.

FIG. 13 is a flowchart of a music reproduction process according to the second embodiment. First, it is determined whether or not the audio mode flag OMF is "1" (step H1). OM
When F is “1”, the play flag PF is “1”.
Is determined (step H2). If the PF is "1", it is determined whether or not the sound generation has started (step H3). If it is not the time to start sounding, it searches the eight received data buffers, searches for an empty buffer, and requests the personal computer 2 to transfer audio data.

FIG. 14A shows the data format of the eight received data buffers. Each received data buffer is designated by a pointer k (0 to 7). DF is a data flag indicating whether or not the received PCM data is written in each reception data buffer. When the DF is "1", it indicates that PCM data has been written, and when the DF is "0", it indicates that the PCM data is empty. Or the PC that was written
The state in which the M data has already been read. YF is a reservation flag indicating whether or not each received data buffer is reserved for writing PCM data. When YF is “1”, it indicates that a reservation has been made, and when YF is “0”, it indicates that no reservation has been made.

In the example of FIG. 14A, out of the eight received data buffers (k), the received data buffer (1) is in a state where all the written PCM data has been read, and the received data buffer (2) has been read. ) Is the written P
This is a state where CM data is being read. The received data buffers (3) to (5) are in a state where the written PCM data has not been read yet. The reception data buffers (0), (6), and (7) are empty with no PCM data and reserved for writing.

In FIG. 13, the value of the register K is substituted for a pointer k for designating a reception data buffer (step H4). Although the value of K changes according to the processing described later,
The initial value is “0”. Therefore, the reception data buffer (0) is specified first. Thereafter, while the value of k is incremented, a reservation is made for an empty reception data buffer. That is, it is determined whether or not the data flag DF (k) of the reception data buffer (k) designated by the pointer k is "0 (empty buffer)" (step H5). If DF (k) is “0”, YF
It is determined whether or not (k) is "0 (unreserved)" (step H6).

If DF (k) is "1 (not empty buffer)" or YF (k) is "1 (reserved)", k is incremented to designate the next received data buffer (step). H7). However, it is determined whether or not the incremented result k becomes “8” (step H8). If k is “8”, k is set to “0” (step H9). Next, it is determined whether or not the value of k is the same as the value of K (step H10). If the value of k is the same as the value of K, a search is made through the eight received data buffers, and all of them are not empty.

If k is equal to or less than "7" in step H8, or if the value of k is different from the value of K in step H10 (if the search is not completed), the process proceeds to step H5 and the next step is performed. Search the received data buffer of. In step H5, DF (k) is “0”,
If YF (k) is “0” in step H6, the reception data buffer is empty and the write reservation has not yet been made, so that YF (k) is set to “1 (reserved)”. (Step H11).

Next, the value of the register S is set to the initial value FF.
(H) is determined (step H12). S
Is the number of the received data buffer that was first reserved for writing. Therefore, the value of S is any of “0” to “7”, and when the value of S is FF (H), it represents an initial state in which writing is not reserved. In this case, the value of k is set to S (step H1).
3). After setting the value of k in S, or in step H12
If the value of S is not FF (H) and the first write reservation has already been made, the value of k + 1 is set to K (step H14). That is, the number of the reception data buffer next to the reception data buffer reserved for writing is set to K.

However, when the value of k is “7”,
Since the value of k + 1 is "8" and there is no corresponding received data buffer, it is determined whether or not the value of K is "8" (step H15). If the value of k is "8",
Since the write reservation is the eighth reception data buffer number "7", the next reception data buffer number "0" is set to K (step H16). Next, an audio data transfer request command is written to the transmission data buffer in order to receive the audio data in the reception data buffer reserved for writing (step H17). Then, this flow ends and the process returns to the main flow.

When the tone generation is started in step H3, the tone pitch data is set in the register RATE (step H18). Then, a voice pronunciation process is executed (step H19). This voice pronunciation process is substantially the same as the flow of the voice pronunciation process of the first embodiment shown in FIG. 12, and therefore the drawings and description are omitted. After the voice pronunciation processing, this flow ends and the flow returns to the main flow.

Next, a description will be given of a musical instrument side reception process executed by the CPU 11 of the electronic musical instrument 1 according to the second embodiment. In FIG. 15, it is determined whether or not the check flag CF is "0" (step J1). CF
Is "0" when the check of the reception data buffer in which the reception data is to be written has not been completed, and when CF is "1", the check has been completed.
If the CF is "0", the CF is set to "1" and the value of S is set to the pointer k for specifying the reception data buffer (step J2). That is, in the music reproduction processing flow of FIG. 13, the reception data buffer for which the writing reservation is first made is specified.

Next, it is determined whether or not DF (k) is "0 (empty)" (step J3). If DF (k) is "0", it is determined whether YF (k) is "1 (reserved)" (step J4). YF
If (k) is "1", it is determined whether or not the received data is a header part (step J5). If it is the header part, it is determined what number data it is (step J6). If the received data is the first data, the received data is data indicating the number of PCM data, so that the received data is stored in the register DZ (step J).
7). Then, this flow ends and the process returns to the main flow.

When the next received data is received, the CF is determined to be "1" in step J1, so that the flow shifts to step 5 to determine whether or not the received data is a header portion. When the received data is the header part, the received data is the second data and the loop start data, so "2" of the two addresses of the header part is subtracted from the received data, and the result is stored in the register LS. Store (step J8). Next, the write address WAD of the reception data buffer designated by k is set to "0 (head address)" (step J9). Then, this flow ends and the process returns to the main flow.

If the received data is not a header in step J5, it is determined whether or not the received data is PCM data (step J10). If the data is PCM data, the received data is written in the area of the address WAD (step J11). Then, it is determined whether the WAD is the last address, DZ-1, (step J12). If the WAD is not the last address, the WAD is incremented (step J1).
3). Thereafter, this flow ends and the process returns to the main flow. Then, while incrementing WAD, PCM
Each time data is received, the received data is written to the area of the address WAD. WAD becomes D in step J12.
When it becomes Z-1, the reservation flag YF (k) is set to "0".
(Step J14) and the data flag DF
(K) is set to "1" (step J15). Next, while CF is reset to “0”, S + 1 is added to k + 1.
Is substituted (step J16). That is, the number of the reception data buffer next to the written reception data buffer is set to S.

However, when the value of k is “7”,
Since the value of k + 1 is "8" and there is no corresponding received data buffer, it is determined whether or not the value of S is "8" (step J17). If the value of k is "8",
Since the write reservation is the eighth reception data buffer number "7", the next reception data buffer number "0" is set to S (step J18). Then, this flow ends and the process returns to the main flow.

At step J10, if the received data is P
If the received data is not the CM data, the flow shifts to the flow of FIG. 16 to determine whether or not the received data is a voice data reuse command (step J19). If the received data is this command, the check flag CF is reset to "0" and the value of k-1 is substituted into the register U (step J20). That is, the number of the reception data buffer in which the reception data is written immediately before the currently specified reception data buffer in the empty state is set to U.

However, since the number of the reception data buffer is “0” to “7”, if k is “0”, the value of U becomes “−1”. Therefore, if the value of U is "-
"1" (step J21), and "-"
In the case of "1", the value of U is set to "7", and the reception data buffer (7) immediately before the reception data buffer (0) is set.
Is specified (step J22). Next, the PCM data in the reception data buffer specified by U is copied to the reception data buffer specified by k (step J23). Then, this flow ends and the process returns to the main flow.

As described above, in the second embodiment,
The electronic musical instrument 1 transmits a transfer request command for requesting the transfer of the audio data corresponding to the lyrics to the external device (the personal computer 2) storing the audio data corresponding to the lyrics when performing the melody accompanied by the lyrics. Communication means for receiving voice data corresponding to the transfer request command from the external device; storage means (RAM 15) for storing a plurality of voice data received by the communication means; Command transmission control means for causing the communication means to transmit a transfer request command for requesting the transfer of a plurality of audio data during the performance.

With the above configuration, the electronic musical instrument 1 reads out the voice data received and stored from the external device during the performance of the melody not accompanied by the pronunciation of the lyric when the melody accompanied by the lyrics is performed, and sends it to the sound source. I do. Therefore, when the melody of the song accompanied by the lyrics is performed, audio data corresponding to the lyrics is received from the personal computer 2 during the prelude or interlude of the song,
Since the voice data is stored in a plurality of voice data buffers, the pronunciation of the voice of the lyrics can be prevented from being delayed.

In the second embodiment, the audio data is received during the prelude or interlude of the music. However, as a modification of the second embodiment, the audio data is received when the music is stopped. You may. That is, audio data may be received before the lyrics of the music to be played are determined and the prelude starts. Alternatively, the audio data may be received both when the music is stopped and during the prelude or interlude of the music. In the case of this modified example, audio data can be transferred with more margin.

Next, a third embodiment will be described. Also in the third embodiment, the system configuration of the electronic musical instrument 1 and the personal computer 2 is the same as that of the first embodiment shown in FIG. The main flow of the CPU 11 of the electronic musical instrument 1 and the flow of the switch processing are the same as those of the first embodiment shown in FIGS. The flow of the command receiving device processing in the CPU 21 of the personal computer 2 is the same as the flow of the first embodiment shown in FIG. Therefore, description overlapping with the first embodiment will be omitted, and the features of the third embodiment will be described below.

FIG. 17 is a flowchart of the audio data transmission process of the personal computer 2 in the third embodiment. First, it is determined whether or not the sound data requested to be transferred from the electronic musical instrument 1 this time is different from the sound data transmitted last time (step K).
1). If the audio data is different, it is determined whether the requested audio data is not specific audio data (step K2). The specific voice data is the voice data of the lyrics frequently used for the music to be played or the P read out from the waveform memory.
This is audio data that requires complicated processing on the CM data. The same PCM data must be transmitted many times for frequently used audio data of lyrics, and for audio data that requires complicated processing, the time from transmission request to transmission is long. turn into. For this reason, such specific audio data is transmitted in advance prior to the performance of the music, and is written in a specific reception data buffer on the electronic musical instrument 1 side.

If the audio data requested to be transferred is not specific audio data, the audio data corresponding to the address of the waveform memory designated by the pointers m and n is read out, and
Write to the transmission data buffer of AM25 (step K
3). Then, every time writing is performed, n is incremented (step K4), and it is determined whether or not there is a prompt sound addition mark (step K5). If there is no prompt sound addition mark, it is determined whether or not the pointer n has exceeded the maximum value of the currently designated pointer m (step K7).

If n is equal to or less than the maximum value, step K
In step 3, the audio data is read from the address of the waveform memory designated by m and n and written to the transmission data buffer. If there is a prompt sound addition mark in step K5, the final address is written to the second address of the transmission data buffer (step K6). Then, in the processing of steps K3 to K7, the audio data of the waveform memory is sequentially written into the transmission data buffer while n is incremented.
Exceeds the maximum value, the voice data is transmitted to the electronic musical instrument (step K8). Then, m is incremented to specify the next audio data, and n is set to "1" to specify the first data of the audio data specified by m (step K9). Next, the character data of the lyrics corresponding to the transmitted voice data is supplied to the VDP 26 (step K10), and this flow ends and returns to the main flow.

In step K1, if the current voice data is the same as the previously transmitted voice data, the voice data reuse command is transmitted without transmitting the voice data corresponding to the transfer request command (step K11). ).
Then, this flow ends and the process returns to the main flow. In step K2, if the audio data requested to be transferred is the specific audio data that has already been transmitted,
Transmit a specific voice data use command (step K1)
2). Then, this flow ends and the process returns to the main flow.

FIG. 18 and FIG. 19 are flow charts of the musical instrument side receiving processing in the third embodiment. In the third embodiment, as in the second embodiment, the RAM 15 has eight reception data buffers (0) to (7), but the reception data buffer (7) designated by the pointer k = "7". )
Only the specific audio data described above is written in advance prior to the performance of the music. Therefore, in response to the audio data transfer request command, the reception data buffers in which the audio data received from the personal computer 2 are written are the seven reception data buffers (0) to (7) specified by the pointers k = “0” to “6”. (6).

In FIG. 18, it is determined whether or not the check flag CF is "0" (step L1). CF
Is "0" when the check of the reception data buffer in which the reception data is to be written has not been completed, and when CF is "1", the check has been completed.
If the CF is "0", the CF is set to "1" and the value of S is set to the pointer k for specifying the reception data buffer (step L2). That is, in the music reproduction processing flow of FIG. 13, the reception data buffer for which the writing reservation is first made is specified.

Next, it is determined whether or not DF (k) is "0 (empty)" (step L3). If DF (k) is “0”, it is determined whether or not YF (k) is “1 (reserved)” (step L4). YF
If (k) is "1", it is determined whether or not the received data is a header part (step L5). If it is the header part, it is determined what number data it is (step L6). If the received data is the first data, the received data is data indicating the number of PCM data, so that the received data is stored in the register DZ (step L
7). Then, this flow ends and the process returns to the main flow.

When the next received data is received, the CF is determined to be "1" in step L1, so that the flow shifts to step 5 to determine whether or not the received data is a header portion. When the received data is the header part, the received data is the second data and the loop start data, so "2" of the two addresses of the header part is subtracted from the received data, and the result is stored in the register LS. Store (step L8). Next, the write address WAD of the reception data buffer designated by k is set to "0 (head address)" (step L9). Then, this flow ends and the process returns to the main flow.

If the received data is not a header in step L5, it is determined whether the received data is PCM data (step L10). If the data is PCM data, the received data is written in the area of the address WAD (step L11). Then, it is determined whether or not the WAD is the last address DZ-1 (step L12). If the WAD is not the last address, the WAD is incremented (step L1).
3). Thereafter, this flow ends and the process returns to the main flow. Then, while incrementing WAD, PCM
Each time data is received, the received data is written to the area of the address WAD. WAD becomes D in step L12.
When it becomes Z-1, the reservation flag YF (k) is set to "0".
(Step L14) and the data flag DF
(K) is set to "1" (step L15). Next, while CF is reset to “0”, S + 1 is added to k + 1.
Is substituted (step L16). That is, the number of the reception data buffer next to the written reception data buffer is set to S.

However, when the value of k is “7”,
Since the value of k + 1 is "8" and there is no corresponding received data buffer, it is determined whether or not the value of S is "8" (step L17). If the value of k is "8",
Since the write reservation is the eighth reception data buffer number "7", the next reception data buffer number "0" is set to S (step L18). Then, this flow ends and the process returns to the main flow.

At step L10, if the received data is P
If the received data is not the CM data, the flow shifts to the flow of FIG. 19 to determine whether or not the received data is a voice data reuse command (step L19). If the received data is this command, the check flag CF is reset to "0", and the value of k-1 is assigned to the register U (step L20). That is, the number of the reception data buffer in which the reception data is written immediately before the currently specified reception data buffer in the empty state is set to U.

However, since the number of the reception data buffer is "0" to "6", if k is "0", the value of U becomes "-1". Therefore, if the value of U is "-
1 is determined (step L21).
In the case of "1", the value of U is set to "6", and the reception data buffer immediately before the reception data buffer number "0" is designated (step L22). Next, the PCM data in the reception data buffer specified by U is copied to the reception data buffer specified by k (step L23). Then, this flow ends and the process returns to the main flow.

If it is determined in step L19 that the received data is not a voice data reuse command, it is determined whether the received data is a specific voice data use command (step L24). If the received data is this command, the PCM data in the received data buffer (7) is copied to the received data buffer specified by the pointer k (= 0 to 6) (step L25). Then, this flow ends and the process returns to the main flow.

As described above, in the third embodiment, the personal computer 2 receives the transfer request command for requesting the transmission of the audio data corresponding to the lyrics from the external device (electronic musical instrument 1) playing the melody accompanied by the lyrics. Receiving means,
Discriminating means for discriminating whether the voice data requested by the transfer request command received by the receiving means is normal voice voice data or specific voice voice data previously transferred; and When it is determined that the voice data is the voice data, the requested voice data is read from a predetermined data storage unit and transmitted to the external device. When the determination unit determines that the voice data is the voice data of the specific voice, the specific voice data is output. Data transmission means for transmitting a use command to the external device.

With the above-described configuration, when the external device that plays the melody accompanied by the lyrics requests the transfer of the audio data corresponding to the lyrics, the personal computer 2 transmits the current audio data requested to be transferred to the specific audio transmitted in advance. In the case of the voice data, a command using the voice data of the specific voice is transmitted without transferring the voice data. Therefore, when a melody of a song accompanied by lyrics is performed, only the specific voice data use command is transmitted for the voice data of the specific voice that has been transmitted in advance, and the transfer time of the voice data of the lyrics can be shortened as a whole. It is possible to prevent the pronunciation of the voice from being delayed.

In the personal computer 2 according to the third embodiment, the time required for receiving the voice data of the specific voice from the reception of the transfer request command from the electronic musical instrument 1 to the transmission of the voice data is compared with the time required for the voice data of the normal voice. If the audio data takes a long time, for example, if it is necessary to process the audio data in response to the reception of a transfer request command, the transfer time of such audio data during a performance is eliminated, and As a result, the transfer time of the lyrics voice data can be greatly reduced, and the pronunciation of the lyrics voice can be prevented from being delayed.

The electronic musical instrument 1 according to the third embodiment
Transmits a transfer request command for requesting transfer of audio data corresponding to the lyrics to an external device (personal computer 2) storing audio data corresponding to the lyrics when the melody accompanied by the lyrics is performed, Communication means for receiving voice data or response data corresponding to the transfer request command from an external device, and first storage means for storing voice data of a specific voice received by the communication means prior to the performance of a melody accompanied by lyrics (One reception data buffer in the RAM 15), second storage means (seven reception data buffers in the RAM 15) for storing the audio data received by the communication means, and the communication means receives the audio data. The voice data stored in the second storage means is read and transmitted to a sound source, and the communication means transmits a specific voice data use command. When the received has a structure having a read control means for sending to the source reads the voice data stored in said first storage means.

According to the above configuration, when the electronic musical instrument 1 receives a command for using the voice data of the specific voice from the external device storing the voice data corresponding to the lyrics, the electronic musical instrument 1 performs prior to the performance of the melody accompanied by the lyrics. The voice data of the specific voice received and stored is read out and transmitted to the sound source. Therefore, when performing a melody of a song accompanied by lyrics, the voice data of the specific voice previously received and written in the predetermined buffer uses the voice data of the specific voice, and the transfer time of the voice data of the lyrics as a whole is reduced. Since it can be shortened, the pronunciation of the lyrics can be prevented from being delayed.

In the electronic musical instrument 1 or the personal computer 2 according to the third embodiment, when the voice data of the specific voice is voice data of lyrics frequently used for the performance of the melody, such voice data is used in the performance. Since the frequent data transfer time is eliminated, the transfer time of the lyrics voice data can be greatly reduced as a whole, and the pronunciation of the lyrics voice can be prevented from being delayed.

In the third embodiment, one of the eight received data buffers is designated for specific audio data. However, two or more received data buffers are designated for specific audio data. May be specified. In this case, since a plurality of different types of specific voices can be handled, the transfer time of the lyrics voice data can be further reduced.

Next, a fourth embodiment will be described. Also in the fourth embodiment, the system configuration of the electronic musical instrument 1 and the personal computer 2 is the same as that of the first embodiment shown in FIG. The main flow of the CPU 11 of the electronic musical instrument 1 and the flow of the switch processing are the same as those of the first embodiment shown in FIGS. However, the command receiving device processing in the CPU 21 of the personal computer 2 is configured to receive a voice data transfer request command from the electronic musical instrument 1 a plurality of times at an arbitrary time. However, the flow of the command receiving device processing is basically the same as the flow of the first embodiment shown in FIG. Therefore, description overlapping with the first embodiment will be omitted, and the features of the fourth embodiment will be described below.

FIG. 20 is a flowchart of the audio data transmission process of the personal computer 2 in the fourth embodiment. First, it is determined whether or not the audio data requested to be transferred from the electronic musical instrument 1 this time is different from the previously transmitted audio data (step M).
1). If the sound data is different, the sound data corresponding to the address of the waveform memory designated by the pointers m and n is read and written to the transmission data buffer of the RAM 25 (step M2). Every time writing is performed, n is incremented (step M3), and it is determined whether or not there is a prompt sound addition mark (step M4). If there is no prompting mark, it is determined whether or not the pointer n has exceeded the maximum value of the currently designated pointer m (step M).
6).

If n is equal to or less than the maximum value, step M
In step 2, the audio data is read from the address of the waveform memory designated by m and n and written to the transmission data buffer. If there is a prompt sound addition mark in step M4, the final address is written to the second address of the transmission data buffer (step M5). Then, in the processing of steps M2 to M6, the audio data of the waveform memory is sequentially written to the transmission data buffer while incrementing n. In step M1,
If the voice data requested to be transferred from the electronic musical instrument 1 this time is the same as the voice data transmitted last time, the voice data reuse command is written in the transmission data buffer (step M7).

When n exceeds the maximum value in step M6, that is, after the transfer-requested audio data is written in the transmission data buffer, or after the command is written in the transmission data buffer in step M7, the transmission data It is determined whether the next audio data can be further stored in the buffer (step M8). If it can be stored, it is determined whether there is enough time to transmit the storable voice data to the electronic musical instrument (step M9).
If there is a time for transmission, m is incremented and n is set to "1" to designate the head of the header portion of the next audio data (step M10). Next, it is determined whether or not the pointer m has exceeded the maximum value (step M11). That is, it is determined whether or not the writing of the last audio data has been completed.

If m is equal to or less than the maximum value and the designated audio data does not exceed the last audio data, the process proceeds to step M
Then, the process goes to step 2 to write the audio data designated by m and n into the transmission data buffer. If the next audio data cannot be stored in the transmission data buffer in step M8, or if the next audio data can be stored, the transmission time cannot be obtained in step M9, or if the last audio data cannot be stored in step M11, When the data writing is completed, a process of transmitting the data in the transmission data buffer is performed (step M12). Next, the character data of the lyrics corresponding to the transmitted voice data and the lyrics corresponding to the voice data reuse command are transmitted to the VDP 26 (step M13). Then, this flow ends and the process returns to the main flow.

In the fourth embodiment, the personal computer 2
Receiving means for receiving a transfer request command for requesting transmission of audio data corresponding to lyrics from an external device (electronic musical instrument 1) playing a melody accompanied by lyrics, and temporarily storing audio data to be transferred to the external device. Temporary storage means for storing, and when the receiving means receives a transfer request command for requesting a plurality of voice data, it can be stored in a storage area of the temporary storage means and can be temporally transferred to the external device Discriminating means for discriminating the number of pieces of audio data, and writing control means for reading the number of pieces of audio data determined by the discriminating means as storable and transferable from predetermined voice data storage means and writing the data to the temporary storage means. It has a configuration to have.

With the above configuration, when the personal computer 2 receives a request to transfer the audio data corresponding to the lyrics from an external device that plays the melody accompanied by the lyrics, the personal computer 2 sets the storage area for transferring the audio data and the transfer time. Depending on the margin,
Determine the number of audio data to be transferred. Therefore, when performing the melody of the song accompanied by the lyrics in the electronic musical instrument 1, the transfer is performed by analyzing the number of audio data that can be transferred. Therefore, by avoiding the transfer failure, the pronunciation of the sound of the lyrics is not delayed. You can do so.

In the fourth embodiment, the voice data transfer request command is received from the electronic musical instrument 1 a plurality of times at an arbitrary time. However, the voice data transfer request command is received during the prelude or interlude of the music. May be received. In this case, since the voice data transfer request command can be received a larger number of times, if the conditions of the personal computer 2 permit, a large amount of voice data can be transmitted to the electronic musical instrument 1 continuously.

Next, a fifth embodiment will be described. In this embodiment, the lyrics data shown in FIG. That is, when the electronic musical instrument 1 requests the personal computer 2 for the PCM data of the voice corresponding to the lyrics, the electronic musical instrument 1 transmits the “RO”, “BO−”, and “TO” of the lyrics data “robot” shown in FIG. Send ASCII data along with the command. Also in the fifth embodiment, the system configuration of the electronic musical instrument 1 and the personal computer 2 is the same as that of the first embodiment shown in FIG. The main flow of the CPU 11 of the electronic musical instrument 1 and the flow of the switch processing are the same as those of the first embodiment shown in FIGS. The electronic musical instrument 1 according to the fifth embodiment
The number of reception data buffers of the RAM 15 is two as in the first embodiment. Hereinafter, description overlapping with the first embodiment will be omitted, and the features of the fifth embodiment will be described.

FIG. 21 shows the CPU 11 of the electronic musical instrument 1.
3 is a flow of a music reproduction process. Voice mode flag OMF
Is determined as “1” (step N1), and OM
If F is "1", it is determined whether or not the play flag PF is "1" (step N2). PF is "1"
If so, it is determined whether or not the melody sounding has started (step N3). If the melody starts to sound,
The pitch data of the sound generation is set in the register RATE (step N4). Next, lyrics data processing is executed (step N5). Next, a voice pronunciation process is executed (step N6). Then, the process returns to the main flow.

If the PF is "0" in step N2, or if the melody tone generation is not started in step N3, this flow ends and the flow returns to the main flow. If the OMF is "0" in step N1, the sound mode is not set, and the normal tone generation process corresponding to the keyboard operation is performed (step N7). Then, this flow ends and the process returns to the main flow.

FIG. 22 is a flowchart of the lyrics data processing in step N5 of the music reproduction processing in FIG. The current lyrics data corresponding to the melody pronunciation is stored in the register KK (step P1). Then, it is determined whether or not the lyrics data of KK is different from the lyrics data corresponding to the previously-sounded voice data stored in the register ZK (step P2). If the two lyrics data are different, an audio data transfer request command is written to the transmission data buffer (step P3). Next, the lyrics data of KK is stored in ZK (step P4). Then, this flow is ended, and the flow returns to the flow of FIG. In step P2, if the current lyrics data is the same as the lyrics data corresponding to the previously pronounced voice data, the reuse flag SF is set to "1" (step P5), and this flow ends. The process returns to the flow of FIG. That is, when the lyrics data in the previous performance is the same as the lyrics data in the current performance, transmission of the voice data transfer request command is prohibited.

FIG. 23 is a flow chart of the sound generation process in step N6 in FIG. First, the reuse flag SF
Is determined to be "0" (step Q1). S
If F is "0", that is, if the voice data reuse command is not received from the personal computer 2, it is determined whether or not the data flag DF is "1" (step Q2). DF
Is "1", the requested PCM data has all been written to the reception data buffer. Therefore, while inverting the RBF, the receiving buffer which has been in the data writing state up to that point is brought into the reading state,
The read address RAD of the received data buffer is set to “0” (first address) (step Q).
3). Next, at the read speed corresponding to the pitch data of RATE set in step N4 of FIG.
The PCM data of D is read out and transmitted to the sound source 16 (step Q4).

Next, RAD is incremented (step Q5). Then, it is determined whether the RAD is the same as the DZ data (step Q6). The data of DZ (the number of PCM data) is a value larger by “1” than the last address. Therefore, when the data of the RAD and the data of the DZ are not the same, it means that the reading of the last PCM data has not been completed. In this case, step Q
4, the PCM data of the RAD is read out at the read speed corresponding to the pitch data of the RATE, and the sound source 16 is read.
To send to.

In step Q6, when the data of the RAD and the data of the DZ are the same, it means that the RAD is "1" more than the last address, and this is the case where the reading of the last PCM data is completed. In this case, it is determined whether or not the LS data is the same as the value obtained by subtracting “1” from the DZ data (step Q7). That is, it is determined whether the PCM data in the reception data buffer is a normal sound or a prompt sound.

In step Q7, the data of LS is D
If the value is not the value obtained by subtracting “1” from the data of Z, the vowel is continuously looped because it is a normal voice. Therefore, the RAD address is rewritten to the LS address (step Q8). And the envelope register EN
It is determined whether or not the envelope value of V is "0", that is, whether or not the sound is muted (step Q9). ENV data is "0"
If not, the process proceeds to step Q 4, where the head PCM data of the loop portion is read at the RATE read speed and transmitted to the sound source 16.

By repeating the processing of steps Q4 to Q9, the PCM data is read out at the RATE reading speed, and the PCM data constituting the vowel is repeatedly output from the sound source 1.
Send to 6. Then, in step Q9, ENV
Is reset to "0", the data flag DF is reset to "0" (step Q10). Then, this flow ends and the process returns to the main flow. In step Q7, if the LS data is a value obtained by subtracting "1" from the DZ data, the data flag DF is reset to "0" (step Q10), and this flow is terminated to return to the main flow. Return.

At step Q1, when the SF is "1", this means that the lyrics data of this time is the same as the lyrics data corresponding to the voice data of the previous sound. In this case, RAD is set to “0” without inverting RBF.
(Step Q11). That is, the head address of the reception data buffer from which the previous reading has been completed is specified again. Then, the process proceeds to step Q4, where the RAT
The same audio data as the previous one in the reception data buffer is transmitted to the sound source 16 at the reading speed of E.

As described above, in the fifth embodiment, the electronic musical instrument 1 includes the lyrics data storage means for storing the lyrics data of the lyrics accompanying the performance of the melody, and the lyrics data stored in the lyrics data storage means. Communication for transmitting a transfer request command requesting transfer of audio data to an external device (personal computer 2) storing the corresponding audio data, and receiving audio data corresponding to the transfer request command from the external device Means, voice data storage means for storing voice data received by the communication means, and if the lyrics data in the previous performance is the same as the lyrics data in the current performance, the communication means Command prohibiting means for prohibiting transmission of a transfer request command for voice data corresponding to lyrics data in performance;
When audio data is received from the external device in response to the transfer request command, the audio data is read out from the audio data storage means and transmitted to a sound source, and when transmission of the transfer request command is prohibited, the previous performance is performed. Read-out control means for reading out the received sound data again from the sound data storage means and sending it to the sound source.

With the above configuration, when the lyrics data of the lyrics accompanying the performance of the melody is the same as the previous lyrics data, the electronic musical instrument 1 does not make a request to transfer the audio data to the external device but sends it to the previous sound source. The transmitted audio data is transmitted to the sound source again. Therefore, when the melody of the song accompanied by the lyrics is played, if the lyrics data generated this time and the lyrics data corresponding to the audio data transmitted to the previous sound source and generated are the same, the audio data is transmitted to the personal computer 2. Since the transfer request command is not transmitted, the previously sounded voice data is read out again from the reception data buffer and transmitted to the sound source, so that the transfer time of the lyrics voice data can be shortened as a whole so that the pronunciation of the lyrics voice is not delayed. Can be
