Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a tone setting device for an electronic musical instrument.

[Summary of the Invention] In the present invention, a desired timbre can be easily and quickly set by dividing a timbre selection operation into two stages of selecting a timbre group and selecting a timbre in a group.

2. Description of the Related Art Conventionally, as a tone setting device for an electronic musical instrument, there has been known a tone setting device which designates a desired tone number by using a numeric keypad or an up / down key and sets a tone corresponding to the tone number.

[Problems to be Solved by the Invention] According to the above-described conventional tone setting device, it is not easy to set a desired tone when the number of tones increases to several tens to several hundreds. That is, when a tone number is designated using the numeric keypad, it is necessary to check the tone color number in the tone color number table, which requires considerable time and labor. Further, when changing the tone color number with the up / down key, it is necessary to repeat the key operation until the desired tone color number is reached, and the operation requires considerable time and labor.

SUMMARY OF THE INVENTION An object of the present invention is to enable a desired tone color to be set easily and quickly from a large number of tone colors.

[Means for Solving the Problems] A timbre setting device for an electronic musical instrument according to the present invention includes the following steps: (a) A plurality of timbres are divided into a plurality of timbre groups as one similar timbre; Selecting means [FIG. 1 UD
S, FIGS. 96 to 102, 130 to 134], and (b) automatic selection means for automatically selecting a predetermined timbre in the timbre group in response to the selection of the timbre group by the first selection means [ FIG. 9 104]; (c) After the predetermined tone is selected by the automatic selecting means, an arbitrary one of a plurality of tones belonging to the tone group selected by the first selecting means is selected. The second selection means for performing the operations [CSW and UDS in FIG. 1 and FIGS. 110 to 119 and 136 in FIG.
146], (d) tone generating means capable of setting tone characteristics, which generates a tone signal having the tone characteristics according to the setting [FIG. 1], and (e) the automatic selecting means. A tone characteristic corresponding to the predetermined tone is set by the tone generator in response to the selection of the predetermined tone, and in response to a tone selected by the second selector. Setting means [FIG. 9 106] for setting the tone color characteristics corresponding to the selected tone color by the tone generating means.

[Operation] According to the configuration of the present invention, a large number of timbres are divided into a plurality of timbre groups as a group of similar timbres such as piano-based and organ-based timbres. Further, the desired tone can be easily and quickly selected by the second selecting means. That is, since the type of instrument desired to be used for performance is usually easily known, the tone group corresponding to the type of instrument can be easily selected by the first selecting means, and thereafter, the tone group in the selected tone group is selected. Select desired tone from second to second
May be selected by the selection means. Therefore, it is possible to avoid the trouble of checking the tone number and repeating the key operation many times.

When a timbre group is selected by the first selecting means,
A predetermined tone in the tone group (step 104 in FIG. 9)
In this case, the first timbre is automatically selected by the automatic selection means, so that the selection operation immediately after the timbre group selection is unnecessary for the predetermined timbre, and the timbre selection operation is simplified.

Outline of Operation (FIGS. 3 and 4) Next, an outline of an edit operation (operation of setting a tone color and a volume) will be described with reference to FIGS.

In FIG. 3, when mod = 0, FIG. 4 (a)
"VOICE" is displayed on the display DSP as shown in FIG. This is the initial screen for editing.

When the right movement switch of the cursor switch CSW is turned on in the mod = 0 state, mod = 1 is set, and the character "ET WAVE" is displayed on the display DSP as shown in FIG. 4 (b). The cursor CS is displayed below the word "WAVE". In the display area R, a channel name (for example, “EA”) of the selected channel is displayed, and a group name (for example, “Piano”) selected for the channel and a selected waveform are displayed. A name (for example, "Cembalo") and a waveform number (for example, "02") corresponding to the waveform name are displayed at the positions shown in the figure.

When the right movement switch is turned on in the state of mod = 1, mod = 2, and the cursor CS moves to the position indicated by the dashed line. In this state, an arbitrary group can be selected by operating the switch UDS, and the group name of the selected group, and the waveform name and waveform number of the first waveform of the group are displayed.

When the right movement switch is turned on in the state of mod = 2, mod = 3, and the cursor moves to the position indicated by the broken line. In this state, an arbitrary waveform (tone color) can be selected for the displayed group name by operating the switch UDS, and the selected waveform name and waveform number are displayed.

In any state of mod = 1 to 3 described above,
The channel to be edited can be selected by operating the switch CHS, and a channel name, a group name, a waveform name, and a waveform number are displayed for the selected channel each time the channel is selected.

When the left movement switch is turned on in the state of mod = 3, the state of mod = 2 is established, and the group selection as described above becomes possible. When the left movement switch is turned on in the state of mod = 2, the state of mod = 1 is set. Further, when the left movement switch is turned on in the state of mod = 1, the mod
= 0.

By the way, when the up switch (+1) or the down switch (-1) is turned on in the state of mod = 1, mo
d = 4, and “VOLUME” as shown in FIG.
The letters “E” and “LEVEL” and the set volume level value (for example, 0) are displayed on the display DSP,
A cursor CS is displayed below the character “LEVEL”.

When the right shift switch is turned on with mod = 4, mod =
5, and the cursor CS moves below the volume level value as shown by the broken line. In this state, the volume level value can be changed by operating the switch UDS, and a new volume level value is displayed each time it is changed.

When the left movement switch is turned on in the state of mod = 5, the state becomes mod = 4. Also, when the left movement switch is turned on in the state of mod = 4, the state of mod = 0 is established, and the up switch (+1) or the down switch (−)
When 1) is turned on, mod = 1 is set.

Main Routine (FIG. 5) FIG. 5 shows the flow of the processing of the main routine, and this routine is started when the power is turned on or the like.

First, in step 30, various registers are initialized. For example, the above-mentioned registers (1) to (6) are all cleared, and a standard volume level value is set in the register VOL of (7). Thereafter, the initial screen shown in FIG. 4A is displayed on the display DSP.

Next, in step 32, key event processing is performed.
The key event processing detects a key event (key-on or key-off event) on the keyboard 20, and if a key-on event, detects a key code (pitch data) corresponding to a pressed key.
And output key-on information to the TG 24 to start sounding the tone corresponding to the key code on each channel, and in the case of a key-off event, output the key code and key-off information corresponding to the released key to the TG 24 and output the key-off information to the TG 24 for each channel. Attenuation of the tone corresponding to the key code is started.

Next, in step 34, a subroutine of a switch (SW) process is executed as described later with reference to FIG.

After that, other processing is performed in step 36, and the process returns to step 32, and the subsequent processing is repeated in the same manner as described above.

SW Processing Subroutine (FIG. 6) FIG. 6 shows a SW processing subroutine. In step 40, it is determined whether or not a switch-on event has occurred on the operation panel 22. If the result of this determination is negative (N), the routine returns to the routine of FIG.

If the determination result of step 40 is affirmative (Y), the process proceeds to step 42, and it is determined which switch has the ON event. As a result of this judgment, the switch
If the event is a CSW or UDS ON event, a CSW / UDS ON subroutine is executed in step 44 as described later with reference to FIG. If the event is the switch CHS ON event, a CHS ON subroutine is executed in step 46 as described later with reference to FIG. If it is an ON event of another switch, other switch processing is performed in step 48.

When the processing of step 44, 46 or 48 is completed, the routine returns to the routine of FIG.

CSW / UDS ON subroutine (FIG. 7) FIG. 7 shows a CSW / UDS ON subroutine. In step 50, whether any of the following conditions (a) to (c) is satisfied? judge.

(A) The right movement switch has mod = 0 and has an ON event.

(B) Mod = 1 and an ON event occurred in any of the left movement switch, down switch (−1) and up switch (+1).

(C) Mod = 4 and an ON event occurred in any of the left movement switch, down switch (−1) and up switch (+1).

When the determination result of step 50 is affirmative (Y), the process proceeds to step 52, and the screen is switched according to the current mode and the switch having the on event. That is,
When the condition (a) is satisfied, the screen shown in FIG. 4 (a) is changed to a screen as shown in FIG. 4 (b). Further, when the condition of (b) is satisfied and the left movement switch is an ON event, the screen as shown in FIG. 4B is changed to a screen as shown in FIG. up/
If the down switch UDS was on event, the fourth
The screen shown in FIG. 13B is changed to a screen shown in FIG. Further, when the condition of (c) is satisfied and the left movement switch is an ON event, the screen is changed from the screen as shown in FIG. 4 (c) to the screen as shown in FIG. If the up / down switch UDS is an ON event, the screen is changed from the screen shown in FIG. 4C to the screen shown in FIG.

When the process of step 52 is completed, the process proceeds to step 54,
The cursor CS is set to the initial position for the new screen after the change. Then, the process proceeds to step 56.

In step 56, a value corresponding to the current screen and the position of the cursor CS is set in mod. That is, in the case of the screen shown in FIG. In the screen shown in FIG. 4B, if the cursor CS is at the position indicated by the solid line in FIG. Mod if in the position of the broken line
Set 3. Further, in the case of the screen shown in FIG. 4C, if the cursor CS is at the position indicated by the solid line in FIG.
Is set to 4, and if it is at the position of the broken line, 5 is set to mod. When the process of step 56 is completed, the process returns to the routine of FIG.

When the determination result of step 50 is negative (N), the process proceeds to step 58, and it is determined whether or not the on event has occurred by the cursor switch CSW. This determination result is positive (Y)
If so, proceed to step 60.

In step 60, the cursor CS is moved according to the current mode (mod value) and the switch where the event occurred (right movement switch or left movement switch). That is, mo
If the right movement switch is an ON event in the state of d = 1, the cursor CS is moved from the position of the solid line to the position of the dashed line in FIG. If it is an ON event, the cursor CS is moved from the position of the dashed line to the position of the broken line in FIG. 4 (b). Also, the on-event of the left movement switch in the state of mod = 3 means that the cursor CS is moved from the position of the broken line to the position of the dashed line in FIG. In the case of the ON event, the cursor CS is moved from the position of the dashed line to the position of the solid line in FIG. 4 (b). Further, when the right movement switch is an ON event in the state of mod = 4, the cursor CS is moved from the position of the solid line to the position of the broken line in FIG.
When the left event switch ON event occurs when mod = 5, the cursor CS is moved from the position indicated by the broken line to the position indicated by the solid line in FIG. 4C.

When the process of step 60 is completed, the process proceeds to step 56,
Set the mode value to mod in the same manner as described above. Then, the process returns to the routine of FIG.

When the determination result of step 58 is negative (N) (for example, when the up / down switch UDS is turned on at mod = 0, 2, 3, or 5), the process proceeds to step 62.
An edit subroutine is executed as described later with reference to FIG. Then, the process returns to the routine of FIG.

CHS ON Subroutine (FIG. 8) FIG. 8 shows a CHS ON subroutine. In step 70, the value of mod is larger than 0 and smaller than 4 (m
od = 1 to 3) Judge. This judgment result is negative (N)
If so, the process returns to the routine of FIG. As a result,
Channel selection: mod = 1 to 3 (screen in Fig. 4 (b))
Only possible when

When the determination result of step 70 is affirmative (Y), the process proceeds to step 72, and it is determined which switch has the ON event. As a result of this determination, if the switch corresponding to channel A has an on event, ELN is set to 0 in step 74, if the switch corresponds to channel B, ELN is set to 1 in step 76, and the switch corresponding to channel C is set to 1 in step 76. If so, 2 is set to ELN in step 78, and if the switch is compatible with channel D, 3 is set to ELN in step 80.

When the processing of step 74, 76, 78 or 80 is completed, the routine proceeds to step 82, where the group number of GN "ELN" is set to n and the waveform number of WN "ELN" is set to W. Then, the process proceeds to step 84. Then, the process proceeds to step 84.

In step 84, the display DSP displays the channel name CHN "ELN", the waveform number W, the group name GRP [n], and the waveform name NAM [W]. Thereafter, the process returns to the routine of FIG.

Edit subroutine (Fig. 9) Fig. 9 shows the edit subroutine.
In step 90, it is determined whether mod = 0. When the up / down switch UDS is turned on with mod = 1 or 4, the process moves from step 50 to step 52 in FIG. 7, so that the routine shown in FIG. 9 is not entered. When the determination result of step 90 is affirmative (Y), the process returns to the routine of FIG. As a result, mo
Editing is possible only when d = 2, 3, or 5.

If the result of the determination in step 90 is negative (N), the flow proceeds to step 92, and it is determined whether or not the down switch (-1) has caused the ON event. If the result of this determination is affirmative (Y), the flow proceeds to step 94.

In step 94, some values of mod are determined. If the result of this determination is that mod = 2, the flow proceeds to step 96. In step 96, the group number of GN [ELN] is 0
If the result of this determination is negative (N), the value of GN [ELN] is decremented by one in step 98. Step 9
If the judgment result of 6 is affirmative (Y), GN
Set [ELN] to 14.

When the process of the switch 98 or 100 is completed, the process proceeds to step 102, and the group number of GN [ELN] is set to n. Then, the process proceeds to step 104, where the leading waveform number of ST [n] is set to WN [ELN].

Next, in step 106, the TG24 is switched to an ELN-compatible channel.
The waveform number of WN [ELN] is output, and the waveform number of WN [ELN] is set to W. Then, the process proceeds to step 108.

In step 108, the waveform number W and the group name GRP
[N] and the waveform name NAM [W] are displayed on the display DSP. As a result, the group name of the newly selected group and the waveform number and waveform name of the first waveform of the group are displayed. After step 108, the process returns to the routine of FIG.

If the result of determination in step 94 is that mod = 3, the flow proceeds to step 110, where it is determined whether the waveform number of WN [ELN] is zero. If the result of this determination is negative (N), step 112
To set the group number of GN [ELN] to n and then check in step 114 whether the waveform number of WN [ELN] is equal to the leading waveform number of ST [n] (WN [ELN] is the leading number in the group) Is the waveform number)? If the result of this determination is affirmative (Y), the routine proceeds to step 116.

In step 116, the value of GN [ELN] is decreased by one. This is processing corresponding to the fact that the waveform immediately before the leading waveform in the group belongs to the immediately preceding group as shown in FIG. 2 (b).

When the determination result of step 114 is negative (N) or when the process of step 116 is completed, the process proceeds to step 118, and the value of WN [ELN] is decreased by one.

When the determination result of step 110 is affirmative (Y), the process proceeds to step 119, in which 160 is set to WN [ELN] and GN [ELN].
Set 14 each.

When the processing of step 118 or 119 is completed, step 12
Move to 0, and set the group number of GN [ELN] to n. Then, the process proceeds to step 106, and the subsequent processing is executed in the same manner as described above. As a result, the newly selected waveform number and waveform name are displayed, and when the group name is changed along with the waveform selection, the new group name after the change is also displayed.

If the result of determination in step 94 is that mod = 5, the flow moves to step 122, and the value of VOL is reduced by one. Then, the process proceeds to step 124.

In step 124, the value of VOL is output to TG24. Then, the value of VOL is displayed on the display DSP by the switch 126.
Thereafter, the process returns to the routine of FIG.

On the other hand, if the decision result in the step 92 is negative (N), it means that the up switch (+1) has been turned on, and the process moves to the step 128.

In step 128, some values of mod are determined. If the result of this determination is that mod = 2, the flow proceeds to step 130, where it is determined whether the group number of GN [ELN] is 14. If the result of this determination is negative (N), the routine proceeds to step 132, where the value of GN [ELN] is increased by one. Step 1
If the determination result of step 30 is affirmative (Y), step 13
Move to 4 and set GN [ELN] to 0.

When the processing of step 132 or 134 is completed, step 10
The process moves to 2 and the subsequent processing is executed in the same manner as described above.

If the result of the determination in step 128 is that mod = 3, the flow proceeds to step 136, and it is determined whether the waveform number of WN [ELN] is 160. If the result of this determination is negative (N), step 13
Move to 8, and increase the value of WN [ELN] by one. Then, after setting the group number of GN [ELN] to n in step 140, it is determined in step 141 whether the value of n is 14. If the result of this determination is negative (N), it means that the value of n was any of 0 to 13, and the routine proceeds to step 142.

In step 142, the waveform number of WN [ELN] is set to the leading waveform number ST [n +
1]. This determination result is positive (Y)
If so, the waveform number of WN [ELN] belongs to the group next to the group indicated by n, and the routine proceeds to step 144.

In step 144, the value of GN [ELN] is increased by one. As a result, the number of the group to which the waveform number of WN [ELN] belongs is set to GN [ELN]. As an example, when the value of WN [ELN] is changed from 4 to 5 in step 138, GN [ELN] is obtained by the processing in steps 140 to 144.
Is changed from 0 to 1.

When the determination result of step 136 is affirmative (Y), the process proceeds to step 146, and WN [ELN] and GN [ELN] are both set to 0.

When the process of step 144 or 146 is completed, or when the determination result of step 141 is positive (Y) or when the determination result of step 142 is negative (N), the process proceeds to step 120, The subsequent processing is executed in the same manner as described above.

If the result of determination in step 128 is that mod = 5, the flow moves to step 148, and the value of VOL is increased by one. Then, the process proceeds to step 124, and the subsequent processing is executed in the same manner as described above.
