In this embodiment, as shown in FIG. 7, a maximum of four voices can be overlaid and simultaneously pronounced as one composite tone color (layer). Note that, in FIG. 7, the 1 voice layer (4) is basically not used because it is basically the same as the single voice, but when it is used as layer data, an additional setting is added.
The tone will be different from that of a single voice.

Next, the operation of the CPU 1 will be described with reference to FIGS.
A description will be given based on the flowchart of No. 1. When the electronic musical instrument of FIG. 1 is powered on, the CPU 1 first proceeds to the processing of step SA1 of the main program of FIG. 8 to initialize the system. This initialization is to clear various registers in the CPU work area 3 _a of the RAM 3. Then, the CPU 1 proceeds to step SA2.

In step SA2, key depression / operator event processing is performed. This key-depression / operator event processing is performed when a key-depression event occurs, that is, when any key on the keyboard 4 is depressed by the performer, and when the setting operator 5 is pressed.
When there is an on event, that is, when the player operates any switch or slider of the setting operator 5. Then, the CPU 1 proceeds to step SA3.

At step SA3, tone color setting processing is performed. The routine of this process is shown in FIG. In this routine, in step SB1, it is determined whether the layer mode or the voice mode is set. If the determination result is "Layer mode", i.e., the player is mode switch 5 _c of setting operators 5 shown in FIG. 5 <L
When the AYER> switch is operated and the ON event is detected in the processing of step SA2 described above,
Go to step SB2.

[0021] In step SB2, the mode switch 5 _c
It is determined whether or not there is an on event of the <EDIT> switch that is operated when the editing is performed. If the result of this determination is "NO", then the operation proceeds to step SB3. At step SB3, it is operated to recombine (rejoin) the layer between the mode switch 5 _c <LREJO
IN> It is determined whether or not there is an ON event of the switch. If the result of this determination is "YES", then step S
Go to B4. In addition, the determination result of step SB2 is "YE
In the case of "S", that is, when there is an <EDIT> switch on event, the process proceeds to step SB4.

At step SB4, the layer data LAYXXX currently selected is stored in the LEBUF3 of the RAM3.
transfer to _b . That is, for example, in the selection switch 5 _d shown in FIG. 5, if a <3> state where the switch is pressed the <INTERNAL> switches, the bank switch <B> switch and number switches, R
AM3 internal layer data area 3 _d banks BANK of (B) a layer data stored in the (3) LAYIB3 (e.g. super piano) LE
Transfer to BUF3 _b . Then, the CPU 1 proceeds to step SB5. On the other hand, if the determination result of step SB3 is "NO", that is, if there is no on-event of the <LREJOIN> switch, the process proceeds to step SB5.

[0023] In step SB5, the mode switch 5 _c
<LAYER> switch, <EDIT> switch, <
It is determined whether or not there is an on event of either the LREJOIN> switch or the <SAVE> switch. If the result of this determination is "NO", the flow returns to the main program of FIG. 8 and proceeds to step SA4. On the other hand,
If the judgment result of step SB5 is "YES", i.e., the mode switch 5 _c when there is ON event of any switches above is to either step SB6~SB9 shown below in accordance with the switch move on.
First, if there is an on event of the <LAYER> switch in FIG. 5, the process proceeds to step SB6.

[0024] At step SB6, performs a selection operation processing layer in accordance with the operation by the player's selection switch 5 _d of setting operators 5 shown in FIG. For example, when the performer sequentially operates the <INTERNAL> switch of the selection switch 5 _d , the <B> switch of the bank switch and the <3> switch of the number switch, the bank of the internal layer data area 3 _d of the RAM 3 is BANK
Layer data LAYIB stored in (3) of (B)
3. For example, a super piano tone color is selected.
Then, the CPU 1 returns to the main program of FIG.
Go to step SA4.

Further, the determination result of step SB5 is "YE
S ”and there is an on event of the <EDIT> switch in FIG. 5, the process proceeds to step SB7. In step SB7, the LEBUF3 _b is used to perform layer data editing processing in response to the player's operation of the selection switch 5 _d of the setting operator 5 shown in FIG.
Return to the main program of step S4 and proceed to step SA4.

Further, the determination result of step SB5 is "YE
S ”and there is an on event of the <SAVE> switch of FIG. 5, the process proceeds to step SB8. In step SB8, after the data storage process of storing the inserted floppy disk layer data stored in LEBUF3 _b into internal layer data area 3 _d and FDD7 the RAM 3, returning to the main program of FIG. 8, step Proceed to SA4.

Further, the determination result of step SB5 is "YE
S ”and there is an on event of the <LREJOIN> switch of FIG. 5, the process proceeds to step SB9. In step SB9, layer rejoin processing is performed. The routine of this process is shown in FIGS.
In this routine, in step SC1, the function switch 5 _a setting input device 5 shown in FIG. 5 <PS
W6> It is determined whether or not there is a switch on event. If the result of this determination is "YES", then step S
Proceed to C2.

At step SC2, LEBU of RAM3
The layer combination mode in which another layer (rejoin layer) is combined with the layer (source layer) stored in F3 _b and the voice combination mode in which a voice (rejoin voice) is combined with the source layer are switched. This process is performed every time there is an ON event of the <PSW6> switch.

As a result, for example, the display (layer combination mode) shown in FIG. 12 and the display (voice combination mode) shown in FIG. 13 are alternately displayed on the display device 6. Figure 1
2 and FIG. 13, the source layer is displayed at the upper right end of the display unit 6, and the join layer and the restart voice are displayed at the lower right end. Then, the CPU 1 proceeds to step SC3. Also, if the result of the determination in step SC1 is "NO", that is, if there is no on-event of the <LREJOIN> switch, the process proceeds to step SC3.

[0030] At step SC3, <PRESET> switch selection switch 5 _d, it is determined whether there is a <INTERNAL> switch-on event of the switch bank switch and number switches. If the result of this determination is "YES", then the operation proceeds to step SC4.

At step SC4, a layer or voice to be combined with the source layer is selected. For example, if the performer selects the switch 5 _d <INTERNA
When the L> switch, the bank switch <C> switch, and the number switch <1> switch are sequentially operated, the internal layer data area 3 of the RAM 3 is
The tone color of the layer data LAYIC1 (for example, ultra strings) stored in (1) of the bank BANK (C) of _d is selected as the join layer.
Then, the CPU 1 proceeds to step SC5. When the result of the determination in step SC3 is "NO", that is,
Select switch 5 _d <PRESET> switch, <IN
If there is no ON event of any of the switches TERALL> switch, bank switch and number switch, the process proceeds to step SC5.

[0032] In step SC5, it is determined whether there is <ENTER> switch on event of the selection switch 5 _d. If the result of this determination is "NO", nothing is done and the process returns to the main program of FIG.
Go to. On the other hand, the judgment result of step SC5 is "YE
If "S", that is, if there is an <ENTER> switch on event, the process proceeds to step SC6.

At step SC6, LEBU of RAM3
Number of free layers of source layer stored in F3 _b S
Check the LSPC. In this embodiment, 0 ≦ SLSPC ≦ 3 since a maximum of 4 voices can be combined in one layer. And CPU
1 proceeds to step SC7 in FIG.

At step SC7, the number RLVC of the used layers of the join layer is confirmed. In this embodiment, one layer can have a maximum of four voices, so that 1 ≦ RLVC ≦ 4. In the voice combination mode, the number of layers RLVC is always 1, so this process is not necessary. Then, the CPU 1 proceeds to step SC8.

In step SC8, it is determined whether the number of layers SLSPC is greater than or equal to the number of layers RLVC. If this determination result is "NO", that is, if the number of used layers of the layer to be rejoined this time is larger than the number of free layers of the source layer and the rejoining cannot be performed, the process proceeds to step SC9. In step SC9, after performing alarm processing such as sounding an alarm or changing the display mode of the display device 6 (for example, blinking), the process returns to the main program in FIG. 8 and proceeds to step SA4.

On the other hand, if the result of the determination in step SC8 is "YES", that is, if the number of used layers of the layer to be rejoined this time is smaller than the number of free layers of the source layer, the process proceeds to step SC10. Step S
At C10, it is determined whether the layer combination mode or the voice combination mode is set. If the result of this determination is "layer combination mode", the operation proceeds to step SC11.

[0037] At step SC11, as shown in FIG. 14, copies the valid layer data of Li join layer transferred to the empty layer of layer data of the source layer stored in LEBUF3 _b of RAM 3. In the example of FIG. 14, a source layer of 2 voice layers and a join layer of 2 voice layers are combined to create a new layer. As the data MSC, the source layer data MSC is used as it is. Then, the CPU 1 proceeds to step SC13.

On the other hand, if the result of the determination in step SC10 is "voice combination mode", step SC1
Go to 2. At step SC12, as shown in FIG. 15, while writing the specification information wbn of the join voice in the area in which the specification information LVCE of the empty layer voice of the layer data of the source layer stored in the LEBUF 3 _b of the RAM 3 is stored, Data MDF of empty layer
After initializing the Y group, the process proceeds to step SC13. In step SC13, as shown in FIG. 16, the display unit 6 displays that the rejoin is normally completed, and then the process returns to the main program in FIG. 8 and proceeds to step SA4.

Here, the description returns to the tone color setting processing routine of FIG. If the result of determination in step SB1 in FIG. 9 is "voice mode", the process proceeds to step SB10. In step SB10, tone color setting processing in the voice mode is performed. Since this process is almost the same as the tone color setting process in the layer mode except for the layer rejoin process, the description thereof will be omitted.

In step SA4 of FIG. 8, sound generation processing is performed. That is, in the layer mode, corresponding voice data is read according to the voice designation information LVCEA to LVCED of each layer A to D of the layer data, and each parameter of each voice data is read based on the data MDFYA to MDFYD of each layer A to D. Are changed and modified, and these voice data are assigned to a plurality of channels of the musical sound synthesizing unit 12 to perform sound generation processing. Further, in the single voice mode, voice data is assigned to one channel of the musical sound synthesizing unit 12 and sound generation processing is performed. Then, the CPU 1 proceeds to step SA5. In step SA5, after performing other processes, the process returns to step SA2 and the above-described processes are repeated. As explained above, in layer mode, a new layer is created by combining the layer set before the restart instruction is given as the source layer and the layer specified after the restart instruction or the voice. be able to.

In the above-described embodiment, the number of layers of layer data is set to four, but the number is not limited to this and may be unlimited. In this case, in the layer rejoin processing of FIG. 10 and FIG. 11 described above, the processing of confirming an empty layer is unnecessary. Further, in the above-described embodiment, an example in which one layer or one voice is combined with the source layer is shown, but the number of layers and / or voices is not limited to this number, and a plurality of layers and / or voices may be included in the source layer. You may make it combine.

[0042]

As described above, according to the present invention, there is an effect that an existing tone color or compound tone color can be arbitrarily added or combined to easily form a new compound tone color tone. Therefore, it is possible to easily increase the variation of the timbre. In addition, since a desired tone color can be created for each component such as an attack portion and a sustain portion, and these can be variously combined to finally form one composite tone color, the tone color can be formed. Will be efficient.
