Based on the SYS.DATA (t2) corresponding to the SYS.NAME stored in the YS (t2), a graphic is displayed on the graphic display unit 21 in FIG. 19 (step D19). Next, 2 is set in the graphic register GRAF (step D20). Then, this flow is ended, and the routine goes to Step C2 in FIG.

If the spectrum selection flag SPECSELF and the system selection flag SYSSELF are both 0, the flow is terminated without performing display change and graphic display, and the process proceeds to step C2 in FIG. In the frame display process of step D1 in FIG. 17, as shown in FIG. 19, the screen displays "play", "stop", "clear", "preset", "tone setting",
The icon switches of the "playing music list" and the "tone color screen" are displayed. The function of each icon switch will be described later.

After displaying the cursor in step C2 of FIG. 15, it is determined whether or not the mouse has been moved (step C4). When the mouse is moved, the cursor position is changed according to the movement (step C5). Next, it is determined whether or not the mouse has been clicked (step C6). If there is no click, the process shifts to step C4 to determine the movement of the mouse. If there is a click, it is determined whether the cursor position is on the list on the screen of FIG. 19 (step C7). If it is at this position, a list selection process is executed (step C8). If the cursor position is not on the list, it is determined whether or not the cursor is on a channel of the display unit 20 (step C9). If it is at this position, a channel setting process is executed (step C10).

If the cursor position is not on the channel, it is determined in the flow of FIG. 16 whether the cursor is on the "clear" icon switch (step C).
11). If it is at this position, a clearing process is executed (step C12). If the cursor position is not on the channel, it is determined in the flow of FIG. 16 whether the cursor is on the "clear" icon switch (step C11). If it is at this position, a clearing process is executed (step C12). If the cursor position is not on the "clear" icon switch, it is determined whether the cursor is on the "performance" icon switch (step C13). If it is at this position, a performance process is executed (step C14).

If the cursor position is not on the "performance" icon switch, it is determined whether or not the cursor is on the "tone screen" icon switch (step C15).
If it is at this position, tone color screen processing is executed (step C16). If the cursor position is not on the "tone screen" icon switch, it is determined whether the cursor is on the "preset" icon switch (step C17). If it is at this position, a preset process is executed (step C18). If the cursor position is not on the "preset" icon switch, it is determined whether or not the cursor is on the "playing music list" icon switch (step C19). When in this position,
This flow is ended, and the process returns to the main flow in FIG.

After the list selection processing in step C8, and after the channel setting processing in step C10,
After the clear processing in step C12, step C1
After the performance process in step 4 or the preset process in step C18, the process moves to step C4 to determine the movement of the mouse. After the tone color screen processing in step C16, the process proceeds to step C2 to execute a tone color setting screen display processing.

FIGS. 20 and 21 show steps A in FIG.
17 is a flowchart of a performance process in step C14 of FIG. 17 and FIG. In FIG. 20, the melody selection flag ME
It is determined whether or not LSELF is 1 (step E).
1). If this flag is 0, the music data to be played has not been selected yet, so this flow is terminated. If this flag is 1 and music data to be played is selected, it is determined whether or not data exists in the buffer area (step E2). When MELSELF is 1, the data of the timbre information of the header part in the music data specified in steps A11 and A12 in FIG. 11 is stored in the buffer area. Therefore, the data in the buffer area is transferred to the sound source (step E3).

When there is no data in the buffer area, for example, when the data of the timbre information in all the channels is deleted and stored in the sequencer, it is determined whether or not there is data in the previous buffer area (step). E
4). If there is data, that is, if the data of the timbre information is stored in the previous buffer area at a stage before erasing the data of the timbre information, the data of the previous buffer area is transferred to the sound source (step E5). If there is no data in the previous buffer area, for example, if the device has been started up for the first time and the timbre information has not yet been set in the song data of the sequencer, the song data cannot be played. Therefore, this flow ends.

After the data has been transferred to the sound source in step E3 or E5, AD (n) which is the first address of the music data is set in the address register AD (step E6). Then, the data MEM of the address
The ΔT (delta time) of (AD) is stored in the register T (step E7). ΔT is represented by an integral multiple of the minimum resolution time. The minimum resolution time is a time represented by an integer (for example, 24) of a time length of a quarter note. Therefore, when the tempo is 120 and the time length of the quarter note is 50 ms, the minimum resolution time is about 21 ms.
Becomes After setting ΔT, it is determined whether the minimum resolution time has elapsed (step E8).

When the minimum resolution time has elapsed, the value of T is decremented (step E9). That is, ΔT set in T as data that is an integral multiple of the minimum resolution time is decremented by the minimum resolution time. Then, it is determined whether or not the value of T has reached 0 (step E).
10). When this value reaches 0, the value of AD is incremented (step E11), and the sequence data of the next address is designated. Then, the contents of the designated sequence data MEM (AD) are determined (step E12). If this data is ΔT, MEM
(AD) is set to T (step E13). Then, the process goes to step E10 to determine the value of T.

If the minimum resolution time has not elapsed in step E8, or if the value of T has not reached 0 in step E10, it is determined whether or not the mouse has been moved (step E14). When the mouse is moved, the cursor position is changed (step E15).
Next, it is determined whether or not the mouse has been clicked (step E16). When the mouse has been clicked, it is determined whether or not the cursor position is on the "stop" icon switch (step E17). If the current position is at this position, a mute process is performed (step E18), and this flow ends. If there is no mouse click in step E16, or if the cursor position at the time of the click in step E17 is not on the "stop" icon switch, the elapse of the minimum resolution time is determined in step E8.

In step E12, MEM (AD)
If the data is an event, the channel of the event is set in the register CH in the flow of FIG. 21 (step E19). Next, it is determined whether the buffer data is used or the previous buffer data is used (step E20). When buffer data is used, the BUF of the channel indicated by CH
It is determined whether or not DATA (CH) has data (step E21). On the other hand, when the previous buffer data is used, the FBUF / DAT of the channel indicated by CH
It is determined whether there is data in A (CH) (step E22). If there is data in any of the buffers, that is, if a timbre has been set, the event is transferred to the sound source (step E23). After transferring the event, or when there is no data in step E21 or step E22, the process shifts to step E11 in FIG. 20 to increment the address of AD.

As described above, according to the above-described embodiment, in the performance state of the music data in which the musical tone is generated by a plurality of channels, the tone color information for each channel is set according to the operation, and the tone color for each set channel is set. The information is transmitted to a predetermined sound source means to generate sound. Therefore, it is possible to simplify the operation of setting the timbre of the music data for generating musical tones by a plurality of channels, and to set the timbre of the specified channel while listening to the sounds of other channels in real time. For this reason, the tone of the channel to be set does not deviate from the overall tone and does not impair the musicality.

In this case, the timbre information for each channel included in the header portion of the original music data input from the sequencer 9 is changed according to the operation to set the timbre information. Therefore, while listening to the sound of an arbitrary channel in real time, the current timbre of that channel can be changed to a desired timbre, and the timbre setting becomes extremely easy.

Further, in this case, since the buffer area as the storage means for storing the changed timbre information and the previous buffer area as the storage means for storing the timbre information before the change are provided, the user does not like the changed timbre information. Even in this case, the tone color information before the change can be immediately reproduced just by clearing the buffer area, and the process can easily be shifted to a new tone color setting.

As is apparent from the flowcharts of FIGS. 27 and 28, the timbre information of an arbitrary channel can be changed, and the changed timbre information can be set as the timbre information of another channel. Therefore, for example, when obtaining the effect of increasing the thickness of the sound, it is possible to easily set the timbre of the multiple play of the same musical instrument.

In the above embodiment, the ROM 3
The program for the tone generation processing stored in the
Has been described, that is, the invention of the apparatus has been described. However, a program for the tone generation processing is stored in a storage medium such as a floppy disk, CD, or MD, and the storage medium is mounted on a general-purpose information processing apparatus such as a personal computer. Thus, a configuration in which the program is read and executed is also possible.

That is, a data input procedure for inputting music data for generating musical tones by a plurality of channels into such a storage medium, and timbre information for each channel in either the performance state or the performance stop state of the music data. A tone setting procedure set in accordance with an operation; and tone generation control for transmitting, to the predetermined sound source means, music data input in the data input procedure and tone information for each channel set in the tone setting procedure in the playing state. The procedure and a program for a tone generation process for executing the procedure are stored. In this case, the invention of the storage medium is realized.
