【Example】

 An embodiment of a test sound generator for an electronic musical instrument according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a functional configuration of an electronic musical instrument such as a sound source module including a test sound generator for an electronic musical instrument according to a first embodiment of the present invention. This electronic musical instrument generates or stops a musical tone based on performance data supplied from an external keyboard device or the like via a communication means according to the MIDI standard.

The electronic musical instrument shown in FIG. 1 is configured to control the overall operation of the electronic musical instrument using a musical instrument control section 10. The musical instrument control section 10 has a read-only memory (ROM) in which a predetermined program for controlling the overall operation and a plurality of tone color parameters and the like are stored via a bus and various kinds of programs necessary for executing the program. A storage unit 12 including a random access memory (RAM) having a working area in which registers and the like are set, a tone color selection button 14a, a test sound generation instruction button 14b, and a volume control knob as operators. A musical instrument operation section 14 including a reference numeral 14c, a MIDI input section 16 connected to an external keyboard device or the like for inputting MIDI data, a tone generator 18, and a display section 20 are connected.

Further, the tone generator 18 is connected to a D / A converter 22, the D / A converter 22 is connected to a low pass filter (LPF) 24, and the LPF 24 is connected via an amplifier 26. Speaker 28 is connected.

The above-mentioned components will be described in more detail below.

The musical instrument control unit 10 is composed of a central processing unit (CPU), a serial interface, an input / output port, a timer, and the like, and monitors the transition of the operating state of each operator of the musical instrument operating unit 14 and performs the transition. When there is, the process corresponding to the transition is executed.

If MIDI data is read from the MIDI input unit 16 and the MIDI data is tone generation instruction data, processing such as instructing the tone generator 18 to generate a tone signal is executed.

As described above, the storage unit 12 is composed of a ROM and a RAM. The ROM stores a program for controlling the operation of this electronic musical instrument, various tone color parameters for tone color setting, and the like. A working area is set in the RAM in which various registers necessary for executing the program are set.

As described above, the musical instrument operating section 14 is provided with a tone color selection button 14a, a test sound generation instruction button 14b, and a volume control knob 14c, and the performer operates these operating elements. By doing so, it is possible to issue a setting instruction to the musical instrument control section 10.

The tone color selection button 14a is operated by the player to select a desired tone color, and in the present embodiment, it is constituted by an up / down switch. When a desired tone color number is selected by operating this tone color selection button 14a, the tone color parameter corresponding to the tone color number stored in the ROM of the storage unit 12 is read out, and the tone color corresponding to the tone color number is read. Will be generated.

The test tone generation instruction button 14b is a button for instructing the generation of a test tone, and the tone color selected by the tone color selection button 14a is actually emitted to the space. When confirming that, the test sound generation instruction button 14b is operated to generate the test sound. In the first embodiment, when the test tone generation instruction button 14b is pressed in the initial setting, the pitch of the pitch "C3 (" C "in the third octave)" is generated only while the button 14b is pressed. When the test tone generation instruction button 14b is once released and then pressed again, the test tone generation instruction button 14b is pronounced at a pitch of "C4 (" C "of the fourth octave)". In this way, each time the test sound generation instruction button 14b is pressed, the sound is produced at the pitch corresponding to the pitch of C3 → C4 → C5 → C6 → C3 → C4 → C5 → C6 ... , It is configured to circulate while changing the pitch of the pitch of the test tone to be pronounced, so that a wide range of test tones can be pronounced from low tone test tone to high tone test tone. Has been done.

The volume adjustment knob 14c is for adjusting the volume of the musical sound emitted from the speaker 28 into the space.

The tone generator 18 generates a digitized musical tone signal based on the pronunciation instruction information, the mute instruction information, the volume information, the pitch information, etc. output from the musical instrument control unit 10. The signal will be output to the D / A converter 22.

The D / A converter 22 converts the digital musical tone signal generated by the tone generator 18 into an analog voltage value. Then, the analog signal output from the D / A converter 22 is input to the LPF 24, and the LPF 24 removes unnecessary harmonic signal components outside the audible band.

The analog signal output from the LPF 24 is input to the amplifier 26, and is amplified by the amplifier 26 to a state where it can be emitted to the space from the speaker 28, and finally is emitted to the space as a musical sound via the speaker 28. Will be done.

FIG. 2 shows an outline of the appearance of the operation panel of this electronic musical instrument. The display unit 20 is composed of a liquid crystal display device, and has a tone color number (Tone) and a tone color name corresponding to the tone color number. Is displayed. In this embodiment, it is displayed that the tone color number is "tone color number [0]: Tone00" and the tone color name corresponding to this tone color number is "piano: Pia no". That is, in this electronic musical instrument, when a desired tone color number is selected by operating the tone color selection button 14a, a tone signal corresponding to the tone color number is generated by the tone generator 18, and the tone generator 18 selects the tone color signal. The selected tone color number and tone color name are displayed on the display unit 20. Then, the sounding instruction is given by the MIDI data input through the MIDI input unit 16.

Next, the operation of the test tone generator for an electronic musical instrument according to the first embodiment will be described step by step with reference to the flow charts of FIGS. In the test tone generator of this electronic musical instrument, a musical tone is generated based on MIDI data input through the MIDI input section 16 by a known technique in a known main routine (not shown). While performing the processing, the operating state of each operator of the musical instrument operating unit 14 is monitored. Then, when a transition based on the operation of each operator of the musical instrument operating unit 14 is detected, the routine shown in the following flowchart is executed corresponding to the transition.

The variable [i] used in the following description is a variable used for Note [i] indicating the pitch, and in correspondence with the pitch, Note [0] = C3 Note [1] = C4 Note [2] = C5 Note [3] = C6. Further, the musical tones produced as test tones at the pitches of “Note [0] = C3” to “Note [3] = C6” are “C3” to “C3” in correspondence with a key string of an external keyboard device or the like. It will be sounded at a pitch equivalent to that when a key corresponding to the pitch of "C6" is pressed.

Further, the variable [j] is a variable indicating the tone color number [j], and can take the values of tone color number [0] to tone color number [127] in the MIDI standard. In the above, the tone color number [0] represents the tone color "piano", the tone color number [1] represents the tone color "organ", and the tone color number [2] is the "bass". .. is set to indicate.

FIG. 3 is a flowchart showing a test sound generation processing routine that is executed when the test sound generation instruction button 14 b of the musical instrument operating unit 14 is pressed.

First, in step S 302, preparation is made for actually producing a test tone by muting all the musical tones currently being produced. Specifically, the envelope of the sound being played is forcibly and rapidly attenuated. By doing so, when a test tone is pronounced, it is possible to prevent mixing of the musical tone and the test tone that are being produced for performance, and it is possible to produce only the test tone. When the process of step 302 is completed, the process proceeds to step S304.

In step S 304, the variable [i] is compared with “3” and it is determined whether or not the variable [i] is larger than “3”. If this determination result is affirmative, that is, if the variable [i] is larger than "3", the process proceeds to step S306, the variable [i] is initialized to "0", and the process proceeds to step S308. The variable [i] is initialized to "0" even when the test tone generator of this electronic musical instrument is turned on and when the tone color is switched.

On the other hand, if the determination result in step S304 is negative, that is, if the variable [i] is smaller than “3”, the process jumps to step S308.

In step S308, the tone color corresponding to the selected tone color number [j], which will be described in detail with reference to the flowchart of FIG. 5, is produced at a pitch of Note [i]. As described above, Note [i] is set such that Note [0] = C3 Note [1] = C4 Note [2] = C5 Note [3] = C6. When the process of step S308 ends, this flowchart ends.

Next, FIG. 4 is a flow chart showing a test sound mute processing routine executed when the test sound generation instruction button is released. In this flowchart, when the musical instrument control section 10 detects that the test sound generation instruction button 14b has been released, the test sound of Note [i] currently being generated is muted in step S402.

That is, unlike step S302 described above, by performing the mute processing similar to that of a normal keyboard device, even if the sound has a lingering sound when the keyboard is released, its tone color can be confirmed by the test sound. It is designed to be able to. When the process of step S402 ends, the process proceeds to step S404.

In step S 404, the variable [i] is incremented by “1” and this flow chart ends. Therefore, for example, if the sound of the pitch "Note [2] = C5" is muted in step S402, "i = 2 + 1 = 3" is set in step S404, and then the test sound generation instruction button is pressed. If 14b is pressed, the determination result in step S304 is negative, so the process jumps to step S308, and a test tone is emitted at a pitch of “Note [3] = C6”. become.

FIG. 5 is a flowchart showing a timbre selection processing routine executed by operating the timbre selection button 14a. First, when the musical instrument control unit 10 detects that the tone color selection button 14a of the musical instrument operating unit 14 has been selected and the tone color number [j] is selected, it corresponds to the tone color number [j] in step S502. Change the tone of the musical tone so that it becomes the tone. For example, if the tone color number [0] is selected as the tone color number [j], it is changed to the tone color of "piano", and the tone color number [1] is selected as the tone color number [j]. If so, it is changed to the tone of "organ". When the process of step S502 is completed, the process proceeds to step S504.

In step S504, the variable [i] is initialized to “0”. Therefore, when the timbre is switched, the test tone to be sounded first is always sounded at the lowest pitch "Note [0] = C3".

When the process of step S504 is completed, the process proceeds to step S506, and the timbre name corresponding to the timbre number [j] is displayed on the display unit 20. For example, when the tone color number [0] is selected as the tone color number [j], the display unit 20 displays "Tone00: Piano" as shown in FIG. When the processing of step S504 is completed, the tone color selection processing routine is completed.

Here, the processing of the flow charts shown in FIGS. 3 to 5 will be described based on the operation example shown in FIG.

First, it is assumed that the tone color number [0] is selected by the tone color selection button 14a. In this case, the flow chart of the tone color selection processing routine shown in FIG. 5 is executed, and in step S502, the tone color of the musical tone is changed to "piano" of tone color number [0], and the step In step S506, the display unit 20 displays “One 00: Piano” (FIG. 6A). Further, in step S504, the variable [i] is initialized to "0".

In order to confirm the tone color of the musical tone actually emitted in the space with respect to the tone color switched to the “piano” as the tone color of the tone color number [0], a test tone generation instruction is issued. It is assumed that the button 14b is pressed. In this case, the flow chart of the test tone generation processing routine shown in FIG. 3 is executed, and first, in step S302, all the musical tones currently being sounded are muted.

Next, the variable [i] is compared with “3” in step S 304. However, since the variable [i] is initialized to “0” in step S 504, the variable [i] is changed. Is smaller than “3”, the process jumps to step S308. In this step S308, the test tone is generated at the pitch of "Note [0] = C3" by the tone color of "Piano (piano)" of tone color number [0] (Fig. 6 ( b)), the flow chart of this test sound generation processing routine is ended.

However, since the test sound is not muted in this test sound generation processing routine, while the test sound generation instruction button 14b is kept pressed, the "piano" of the tone color number [0] is displayed. The test tone continues to be produced at a pitch of “Note [0] = C3” with the tone color.

When the test sound generation instruction button 14b is released from the state where the test sound generation instruction button 14b is pressed, the flowchart of the test sound mute processing routine shown in FIG. 4 is executed, and in step S402, “Note [0] = The test sound of the pitch "C3" is muted. Then, in step S404, the variable [i] is incremented by "1" and set to "i = 1", and the flow chart of the test sound deadening processing routine is ended.

Further, when the test sound generation instruction button 14b is pressed in this state, the flow chart of the test sound generation processing routine shown in FIG. 3 is executed again. First, in step S302, the sound is being produced. All tones are muted.

Next, in step S304, the variable [i = 1] is compared with “3”, but since the variable [i = 1] is smaller than “3”, the process also jumps to step S308. Will proceed. In this step S308, the test tone is produced at the pitch of "Note [1] = C4" by the tone color of "piano" of tone number [0] (Fig. 6 (c )), The flow chart of this test sound generation processing routine is ended. As described above, since the test tone is not muted in this test tone generation processing routine, while the test tone generation instruction button 14b is being held down, the "piano" of the tone color number [0] is held. The test tone continues to be produced at the pitch of the pitch “Note [1] = C4” by the tone color “.

When the test sound generation instruction button 14b is released from the state in which the test sound generation instruction button 14b is pressed, the flow chart of the test sound mute processing routine shown in FIG. 4 is executed, and “Note [1] =” in step S402. The test sound of the pitch "C4" will be muted. Then, in step S404, the variable [i] is incremented by "1" and set to "i = 2".

Similarly, each time the test sound generation instruction button 14b is released, the variable [i] is incremented by "1" in step S404, and it is assumed that "i = 3" is set. In this state, when the test sound generation instruction button 14b is pressed, in step S308, the pitch of "Note [3] = C6" is produced by the pitch of "Note (3) = C6" by the tone color of "piano" of the tone color [0]. A test tone is produced (Fig. 6 (d)).

Then, the test sound generation instruction button 14b is released from this state, the test sound is muted in step S402, and [i] is incremented by "1" in step S404 to set [i = 4]. It is assumed that the test sound generation instruction button 14b is pressed again. In this case, since “i = 4”, the determination result of step S304 becomes affirmative, the process proceeds to step S306, the variable “i” is initialized to “0”, and then the process proceeds to step S308. Become. Therefore, in step S308, the test tone is sounded at the pitch of "Note [0] = C3" with the tone color of "piano" of tone number [0] (FIG. 6). (E)).

In this way, each time the test tone generation instruction button 14b is pressed, the test tone to be generated is generated like the pitch of C3 → C4 → C5 → C6 → C3 → C4 → C5 → C6 ... Since the pitch of the pitch changes and circulates, it is possible to check the timbre in a wide range of pitches from low to high pitches.

Note that when the tone color selection button 14a is operated to switch from the tone color [0] "piano (piano)" tone color to the tone number [2] "bass" tone color. Processing similar to that described above with reference to FIGS. 6A to 6E is performed. That is, the variable [i] is initialized to "0" in step S504. Then, when the test tone generation instruction button 14b is pressed thereafter, the test tone is sounded at the pitch of "Note [0] = C3" by the tone color of "bass" of tone number [2]. (FIG. 6 (f)).

FIG. 7 is a flow chart showing a modification of the test sound generation processing routine of FIG. 3 of the first embodiment shown in FIGS. 3 to 5.

Also in the modification of FIG. 7, the variable [i] is initialized to “0” at the time of turning on the power and at the time of switching the timbre. The test sound deadening processing routine and the tone color selection processing routine are the same as those in the flowcharts shown in FIGS.

First, in step S 702, as in the flowchart of FIG. 3, all musical tones currently being sounded are muted, and preparation is made to generate a test sound. Specifically, the envelope of the musical tone being sounded is forcibly and rapidly attenuated. By doing so, when a test tone is pronounced, it is possible to prevent the musical tone and the test tone that are being played for performance from being mixed, and it is possible to produce only the test tone. When the process of step S702 is completed, the process proceeds to step S704.

In step S 704, the variable [i] is compared with “3” to determine whether or not the variable [i] is larger than “3”. If the result of this determination is affirmative, that is, if the variable [i] is larger than "3", then the processing advances to step 706, the variable [i] is initialized to "0", and the processing advances to step S708. The variable [i] is initialized to "0" even when the test tone generator of the electronic musical instrument is turned on and the tone color is switched.

On the other hand, if the determination result in step S704 is negative, that is, if the variable [i] is smaller than “3”, the process jumps to step S708.

In step S708, it is determined whether or not the variable [i] is equal to “0”. If this determination result is affirmative, that is, if "i = 0", the process proceeds to step S710.

In step S710, a test tone is produced with a tone color number [j] and a pitch of C3. When the process of step S710 ends, the process of this flowchart ends.

On the other hand, if the determination result in step S708 is negative, that is, if the variable [i] is not “0” (in this case, “i ≧ 1”), the process proceeds to step S712. ..

In step S712, it is determined whether or not the variable [i] is equal to “1”. If this determination result is affirmative, that is, "i = 1", the process proceeds to step S714.

In step S714, a test tone is produced with the tone color number [j] and the pitch of C4. When the process of step S714 ends, this flowchart ends.

On the other hand, if the determination result of step S712 is negative, that is, if the variable [i] is not “1” (in this case, “i ≧ 2”), the process proceeds to step S716. ..

In step S716, it is determined whether the variable [i] is equal to “2”. If this determination result is affirmative, that is, "i = 2", the process proceeds to step S718.

In step S718, a test tone is produced with a tone color of [j] and a pitch of C5. When the process of step S718 ends, this flowchart ends.

On the other hand, if the determination result in step S716 is negative, that is, if the variable [i] is not “2” (in this case, “i = 3”), the process proceeds to step S720. ..

In step S720, a test tone is generated with a tone color of [j] and a pitch of C6. When the process of step S720 ends, this flowchart ends.

Therefore, also in the flow chart of the test tone sounding process shown in FIG. 7, C3 → C4 → C5 → C6 → C3 → C4 → C5 → C6 ... Depending on the tone color selected by operating the tone color selection button 14a. You can check the tone color by making the test tone sound in a wide range of bass and treble while changing the pitch to be circulated like the pitch of.

8 to 10 are flow charts showing a second embodiment of the test tone generator for an electronic musical instrument according to the present invention. It should be noted that the block diagram and the outline view of the appearance of the operation panel are referred to FIGS. 1 and 2 described in the first embodiment, and detailed description thereof will be omitted. In the second embodiment, the pitch sequence of pitches that can be pronounced as a test tone is constant in the first embodiment and does not change depending on the timbre, whereas, for example, timbre: pitch sequence is supported. Pitch Piccolo: C4 → C5 → C6 → C7 → C4 → C5 → C6 → C7 ... Piano: C3 → C4 → C5 → C6 → C3 → C4 → C5 → C6 ... Wood Bass: C2 → C3 → C4 → C5 → C2 → C3 → C4 → C5 ... In this way, when the pitch range of the optimum tone range is stored in the storage unit 12 in advance and the tone color is selected by the tone color selection button 14a, The test tone is generated at the pitch sequence set for the selected tone color. That is, the pitch sequence of pitches produced as a test tone is changed for each selected tone color.

That is, in the present embodiment, a pitch sequence to be pronounced as a test tone is preset for each tone color stored in the storage unit 12, and is stored in the storage unit 12 as follows, for example. ing.

First, with regard to the timbre, “N” timbres are set, timbre number [0]: piccolo timbre number [1]: piano (piano) N-2]: wood bass tone color number [N-1]: synthesizer (synth).

For these timbres, timbre number [0]: Piccoro: Note [0] = C4 Note [1] = C5 Note [2] = C6 Note [3] = C7 A pitch string corresponding to the pitch is set, and a tone number [1]: for a piano, note [0] = C3 Note [1] = C4 Note [2] = C5 Note [3] = C6 note A pitch sequence corresponding to high is set, and tone color number [N-2]: For wood bass: Note [0] = C2 Note [1] = C3 Note [2] = C4 Note [3] = A pitch sequence corresponding to the pitch of C5 is set, and tone color number [N-1]: Regarding synthesizer (synth), Note [0] = C2 Note [1] = 3 Note [2] = C4 Note [3] = C5 pitch sequence corresponding to the pitch of the are set.

The flow charts of FIGS. 8 to 10 are executed based on the above-mentioned stored contents stored in the storage unit 12.

FIG. 8 is a flowchart showing a test sound generation processing routine that is executed when the test sound generation instruction button 14b of the musical instrument operating unit 14 is pressed.

First, in step S802, preparation is made for actually producing a test tone by muting all the musical tones currently being produced. Specifically, the envelope of the sound being played is forcibly and rapidly attenuated. By doing so, when a test tone is pronounced, it is possible to prevent mixing of the musical tone and the test tone that are being produced for performance, and it is possible to produce only the test tone. When the process of step 802 ends, the process proceeds to step S804.

In step S 804, the variable [i] is compared with “3” and it is determined whether or not the variable [i] is larger than “3”. If the determination result is affirmative, that is, if the variable [i] is larger than "3", the process proceeds to step S806, the variable [i] is initialized to "0", and the process proceeds to step S808. The variable [i] is initialized to "0" even when the test tone generator of this electronic musical instrument is turned on and when the tone color is switched.

On the other hand, if the determination result in step S804 is negative, that is, if the variable [i] is smaller than “3”, the process jumps to step S808.

In step S808, the pitch of the pitch of Note [i] in the pitch row corresponding to the tone color number [j] is selected with the tone color corresponding to the selected tone color number [j] described in detail in the flowchart of FIG. Pronounce with. When the process of step S808 ends, the flowchart of this test sound generation processing routine ends.

Next, FIG. 9 is a flowchart showing a test sound mute processing routine that is executed when the test sound generation instruction button 14b is released. In this flowchart, when the musical instrument control unit 10 detects that the test sound generation instruction button 14b has been released, the test sound of Note [i] of the tone color number [j] currently being generated is muted in step S902. Then, the process proceeds to step S904, the [i] is incremented by "1", and this flowchart ends.

That is, unlike step S802 described above, by performing the mute processing similar to that of a normal keyboard device, even if a sound having a lingering sound at the time of releasing the keyboard is detected, its tone color is confirmed by the test sound. It is designed to be able to.

FIG. 10 is a flowchart showing a tone color selection process executed by operating the tone color selection button 14a. First, when the musical instrument control section 10 detects that the timbre selection button 14a of the musical instrument operating section 14 is operated to select the timbre number [j], the timbre corresponding to the timbre number [j] is selected in step S1002. Change the timbre of the musical sound so that That is, if the tone color number [0] is selected as the tone color number [j], the tone color is changed to the "piccoro" tone color, and the tone color number [1] is selected as the tone color number [j]. If so, the tone color is changed to "piano (o)", and if tone number [N-2] is selected as tone number [j], it is changed to "wood bass" tone. It is supposed to be changed. When the process of step S1002 ends, the process proceeds to step S1004.

In step S1004, it is determined whether the variable [j] is equal to “0”. If this determination result is affirmative, that is, "j = 0", the process proceeds to step S1006.

In step S1006, the pitch sequence preset for the timbre “Piccolo” of the timbre number [0], Note [0] = C4 Note [1] = C5 Note [2] = C6 Note [3]. = C7 will be selected. In this way, the pitch string corresponding to the timbre selected by operating the timbre selection button 14a is selected, and this pitch string is used when the test tone is emitted. When the process of step S1006 ends, the process proceeds to step S1008.

If the determination result of step S1004 is negative, that is, if the variable [j] is not “0” (in this case, “j ≧ 1”), the process proceeds to step S1010. ..

In step S1010, it is determined whether the variable [j] is equal to “1”. If this determination result is affirmative, that is, if the variable [j] is "1", the process proceeds to step S1012.

In step S1012, a pitch string preset for the tone color “piano” of the tone number [1], Note [0] = C3 Note [1] = C4 Note [2] = C5 Note [ 3] = C6 will be selected. In this way, as described in step S1006, the pitch string corresponding to the timbre selected by operating the timbre selection button 14a is selected, and this pitch string is used when the test tone is sounded. When the process of step S1012 is completed, the process proceeds to step S1008.

If the determination result of step S1010 is negative, that is, if the variable [j] is not “1” (in this case, j ≧ 2), then in the next determination step, It will be determined whether the variable [j] is "2", and if the variable [j] is "2", the pitch sequence set for the timbre of the timbre number [2] will be selected. become . If the variable [j] is not "2", increment "2" by "1", compare "3" with the variable [j], and perform the same processing as above. become .

In this way, the same processing as described above is sequentially performed until the variable [j] is equal to “N−3”, and if the variable [j] is not “N−3”, the process proceeds to step S1014. It will be.

In step S1014, it is determined whether the variable [j] is equal to “N−2”. If this determination result is affirmative, that is, if the variable [j] is “N−2”, the process proceeds to step S1016.

In step S1016, a pitch sequence preset for the tone color “N-2”, “wood bass”, “Note [0] = C2 Note [1] = C3 Note [2”. ] = C4 Note [3] = C5 is selected, and the pitch string corresponding to the timbre selected by the operation of the timbre selection button 14a is selected, and this pitch string is used when the test tone is pronounced. Will be. When the process of step S1016 is completed, the process proceeds to step S1008.

If the determination result of step S1014 is negative, that is, if the variable [j] is not “N−2” (in this case, “j = N−1”), then step S10. Proceed to 18.

In step S1018, a pitch sequence that is preset for the “synthesizer” that is the timbre of the timbre number [N−1], that is, Note [0] = C3 Note [1] = C4 Note [2] = C5 Note. [3] = C6 will be selected. When the process of step S1018 ends, the process proceeds to step S1008.

As described above, when the tone color number is selected by the tone color selection button 14a, the tone color of the musical tone is switched to the tone color set to correspond to the tone color number selected in advance, and the tone color is selected. A pitch sequence of test tone pitches preset to be suitable for the tone color is also selected. In this way, after the pitch sequence of the test tone set to the selected tone color is selected, the process proceeds to step S1008 in any case.

In step S1008, the variable [i] is initialized to “0”. Therefore, if the test tone generation instruction button 14b is operated immediately after the tone color is switched by operating the tone color selection button 14a, the test tone is produced at the lowest pitch in the pitch row. Become. When the process of step S1008 ends, the process proceeds to step S1020.

In step S1020, the display unit 20 displays the tone color number and tone color name selected by operating the tone color selection button 14a. When the process of step S1020 is completed, the flowchart of the tone color selection process routine is completed.

In the second embodiment described above, when the tone color is selected by operating the tone color selection button 14a, a test tone is generated based on the operation of the test tone generation instruction button 14b. A pitch string of pitches suitable for the range of the tone color, which is stored in advance in association with the selected tone color, is selected and sounded. Therefore, it is possible to confirm the selected tone color in the range corresponding to the actual performance.

11 to 13 are flow charts showing a third embodiment of the test tone generator for an electronic musical instrument according to the present invention. It should be noted that the block diagram and the outline view of the appearance of the operation panel refer to FIGS. 1 and 2 described in the first embodiment, and detailed description thereof will be omitted. In the third embodiment, the pitch that can be pronounced as a test sound changes in the first embodiment, while the pitch is constant, but the velocity changes. Is different from the first embodiment. That is, the pitch of the pitch produced as the test tone is constant, but the velocity indicating the strength of the touch when the key is pressed is changed.

The variable [i] used in the following description is a variable used for Velo [i] indicating velocity. In terms of the relationship between the magnitude of the velocity when the key is pressed, that is, the strength of the touch, Velo [0]: Weak Velo [1]: Medium Velo [2]: Strong Velo [3]: Strongest correspondence Is set to be the touch strength of. Further, the pitch of the musical tone to be sounded as the test tone at the touch strength of “Velo [0]: weak” to “Velo [3] = strongest” is in correspondence with the key sequence of an external keyboard device or the like. , A pitch corresponding to the pitch of "C3" is pressed.

The variable [j] is a variable indicating the tone color number [j], and can take the values of tone color number [0] to tone color number [127] in the MIDI standard. The tone number [0] represents the tone "piano", the tone number [1] represents the tone "organ", and the tone number [2] is the "bass". .. is set to indicate.

FIG. 11 is a flowchart showing a test sound generation processing routine executed when the test sound generation instruction button 14b of the musical instrument operating section 14 is pressed.

First, in step S1102, preparation is made for actually producing a test tone by muting all the musical tones currently being produced. Specifically, the envelope of the musical tone being sounded is forcibly attenuated. By doing so, when a test tone is pronounced, it is possible to prevent the musical tone that is being pronounced for performance from being mixed with the test tone, and it is possible to produce only the test tone. When the process of step 1102 ends, the process advances to step S1104.

In step S1104, the variable [i] is compared with “3” to determine whether or not the variable [i] is larger than “3 2”. If the result of this judgment is affirmative, that is, if the variable [i] is larger than "3", then the processing advances to step S1106, the variable [i] is initialized to "0", and the processing advances to step S1108. The variable [i] is initialized to "0" even when the power of the test tone generator of this electronic musical instrument is turned on and the tone color is switched.

On the other hand, if the determination result of step S1104 is negative, that is, if the variable [i] is smaller than “3”, the process jumps to step S1108.

In step S1108, a test tone is generated with a velocity of Velo [i] at a pitch of "C3" with a tone color corresponding to the selected tone color number [j] described in detail in the flowchart of FIG. .. As described above, the velocity of Velo [i] is set such that Velo [0]: weak Velo [1]: medium Velo [2]: strong Velo [3]: strongest touch strength. When the process of step S1108 ends, the flow chart of this test sound generation process routine ends.

Next, FIG. 12 is a flowchart showing a test sound mute processing routine executed when the test sound generation instruction button 14b is released. In this flowchart, when the musical instrument control section 10 detects that the test sound generation instruction button 14b has been released, the test sound of Note [i] currently being generated is muted in step S1202.

That is, unlike the above-described step S1102, by performing the mute processing similar to that of a normal keyboard device, even if a sound having a lingering sound at the time of releasing the keyboard is detected, its tone color is confirmed by the test sound. It is designed to be able to. When the process of step S1202 ends, the process proceeds to step S1204.

In step S1204, the variable [i] is incremented by “1” and this flowchart ends. Therefore, for example, in step S1202, if the pronunciation of the test sound with the velocity “Velo [2] = strong” is muted, in step S1204, “i = 2 + 1 = 3” and the test sound is generated next. If the instruction button 14b is pressed, the result of the determination in step S1104 is negative, so the process jumps to step S1108 to produce a test tone with a velocity of “Velo [3] = strongest”. It will be.

FIG. 13 is a flowchart showing a tone color selection processing routine executed by operating the tone color selection button 14a. First, when the musical instrument control section 10 detects that the tone color number [j] is selected by operating the tone color selection button 14a of the musical instrument operating section 14, it corresponds to the tone color number [j] in step S1302. Change the tone color of the musical tone so that it becomes the tone color. For example, if the timbre number [0] is selected as the timbre number [j], it is changed to the timbre of "piano", and the timbre number [1] is selected as the timbre number [j]. If so, it is changed to the tone of “organ”. When the process of step S1302 ends, the process advances to step S1304.

In step S1304, the variable [i] is initialized to “0”. Therefore, when the timbre is switched, the test tone to be sounded first is always sounded with the velocity of the touch strength "Velo: Weak", which is the weakest touch.

When the process of step S1304 is completed, the process advances to step S1306 to display the tone color name corresponding to the tone color number [j] on the display unit 20. For example, if the tone color number [0] is selected as the tone color number [j], the display unit 20 displays "Tone 00: Piano" as shown in FIG. When the processing of step S1306 is completed, the tone color selection processing routine is completed.

Here, the processing of the flow charts shown in FIGS. 11 to 14 will be described based on the operation example shown in FIG.

First, it is assumed that the tone color number [0] is selected by the tone color selection button 14a. In this case, the flow chart of the timbre selection processing routine shown in FIG. 13 is executed, and in step S1302, the timbre of the musical tone is changed to "piano" of the timbre number [0], and the step is executed. In step S1306, “Tone 00: Piano” is displayed on the display unit 20 (FIG. 14A). Further, in step S504, the variable [i] is initialized to "0".

In order to confirm the tone color of the musical tone actually emitted in the space with respect to the tone color switched to the “piano” which is the tone color number [0] in this way, a test tone generation instruction is issued. It is assumed that the button 14b is pressed. In this case, the flow chart of the test sound generation processing routine shown in FIG. 11 is executed, and first, in step S1102, all the musical tones currently being sounded are muted.

Next, the variable [i] is compared with “3” in step S1104, but since the variable [i] is initialized to “0” in step S1304, the process jumps to step S1108. And then proceed. In this step S1108, a test tone is produced with the pitch of "C3" and the velocity of the touch strength of "Velo [0]: weak" by the tone of "piano" of the tone number [0]. A sound is produced (FIG. 14B), and the flow chart of this test sound generation processing routine is ended. However, since the test tone is not muted in this test tone generation processing routine, while the test tone generation instruction button 14b is kept pressed, the tone color [0] of "piano" As a result, the test tone continues to be produced with the pitch of “C3” and the velocity of the touch strength of “Velo [0]: Weak”.

When the test sound generation instruction button 14b is released from the state where the test sound generation instruction button 14b is pressed, the flow chart of the test sound mute processing routine shown in FIG. 12 is executed, and in step S1202, “C3” is executed. The pitch test of the pitch of and the test sound of the velocity of the touch strength of "V elo [0]: Weak" are muted. Then, in step S1204, the variable [i] is incremented by "1" and set to "i = 1", and the flow chart of this test sound mute processing routine is ended.

Furthermore, when the test sound generation instruction button 14b is pressed from this state, the flow chart of the test sound generation processing routine shown in FIG. 11 is executed again. First, in step S1102, all of the currently sounding notes are being generated. Music sounds are muted.

Next, in step S1104, the variable [i = 1] is compared with the numerical value “3”. Since the variable [i] is smaller than “3”, the process also jumps to step S11 08. Will proceed. In this step S1108, with the tone color of the tone number [0] "piano", the pitch of the pitch of "C3" and the velocity of the touch strength of "Velo [1]: Medium" Will be sounded (FIG. 14C), and the flow chart of this test sound generation processing routine will be ended. As described above, in this test sound generation processing routine, the test sound is not muted. Therefore, while the test sound generation instruction button 14b is held down, the "piano" of the tone color number [0] is displayed. With the tone of “”, the test tone continues to be produced with the pitch of “C3” and the velocity of the touch strength of “Velo [1]: Medium”.

When the test sound generation instruction button is released from the state in which the test sound generation instruction button 14b is being pressed, the flowchart of the test sound mute processing routine shown in FIG. 12 is executed, and in step S1202, the sound of “C3” is generated. The high pitch and “Velo [1]: Medium” velocity touch test sounds will be muted. Then, in step S1204, the variable [i] is incremented by "1" and set to "i = 2".

Similarly, each time the test sound generation instruction button 14b is released, the variable [i] is incremented by "1" in step S1204, and it is assumed that "i = 3" is set. When the test sound generation instruction button 14b is pressed in this state, in step S1108, the pitch of the pitch "C3" and "Velo [3]:" by the sound of the "piano" of the sound number [0]: A test sound is generated with a velocity of "strongest" touch strength (Fig. 14 (d)).

Then, the test sound generation instruction button 14b is released from this state, the test sound is muted in step S1202, the variable [i] is incremented by “1” in step S1204, and “i = 4” is set. It is assumed that the test sound generation instruction button 14b is pressed again. In this case, since “i = 4”, the determination result of step S1104 is affirmative, the process proceeds to step S1106, the variable “i” is initialized to “0”, and then the process proceeds to step S1108. Become. Therefore, in step S1108, the test tone is generated with the pitch of "C3" and the velocity of the touch strength of "Velo [0]: Weak" by the tone of "Piano" with the tone number [0]. (Fig. 14 (e)).

In this way, each time the test sound generation instruction button 14b is pressed, the test sound to be generated is sounded like touch strength of weak → medium → strong → strongest → weak → medium → strong → strongest. Since the velocity of the touch strength changes and circulates, it is possible to confirm a wide range of touch strength test sounds from weak touches to strong touches.

Even when the tone color selection button 14a is operated to switch from the tone color "0" "piano" tone color to the tone number "2" "bass" tone color, FIG. The same processing as described above is performed based on FIG. 14 (e). That is, the variable [i] is initialized to "0" in step S1304. Then, when the test sound generation instruction button 14b is pressed after that, the pitch of the pitch of "C3" and the touch strength of "Velo [0]: weak" are selected by the tone of "bass" of tone number [2]. The velocity causes the test sound to be generated (FIG. 14 (f)).

In each of the above embodiments, the test sound is muted by releasing the test sound generation instruction button. However, the present invention is not limited to this, and the test sound is generated for a certain period of time. It may be set so that the sound is muted after the time elapses.

Further, in each of the above-described embodiments, the electronic musical instrument to which the pronunciation instruction is input from the outside by the communication means based on the MIDI standard has been described. However, the communication means based on the original standard is used instead of the MIDI standard. Of course, it may be used, and of course, it may be used in an electronic musical instrument having a keyboard device or the like capable of giving a sounding instruction inside the device.

[0130] The pitch sequence and the strength of velocity generated as a test tone may be arbitrarily set by the performer in advance.

In particular, in the second embodiment described above, the player may be allowed to arbitrarily set the pitch string to be pronounced as a test sound for each tone color in advance, or the tone color parameter setting state may be set. The pitch string to be sounded may be changed according to (for example, a tuning setting value). That is, if the pitch string is initially set to correspond to the pitch range of "C3" to "C6", and the tune parameter for setting the pitch of the tone color is lowered by one octave, The pitch sequence of the pitch range of "C2" to "C5", or the pitch sequence of the pitch range of "C4" to "C7" may be selected if the tone color is raised by one octave. ..

In addition, in both the first and second embodiments, the velocity and the velocity may be controlled by using a touch sensor for the test sound generation instruction button. That is, by using a touch sensor for the test sound generation instruction button, it is possible to generate a test sound with the user's voluntary strength, similar to the case where a normal keyboard is used to make a test play with strength. ..

Furthermore, in the first and second embodiments, the test tone is generated for four pitches in one octave interval in any tone color. However, depending on the musical instrument, Taking into account that some musical tones have a narrow musical range, or conversely, some have a large musical range such as a piano, the musical range of the test tone generated may be changed. For example, for tone colors other than piano tones, four test tones are generated at one octave intervals, and for piano tones, seven test tones are generated at one octave intervals.

Further, in the third embodiment, the touch strength is changed similarly to the test sound in any tone color, but the touch strength may be changed according to the selected tone color.

Further, in the above-mentioned embodiment, the generation of the rhythm sound such as the snare drum and the ride cymbal was not described, but the present invention can be applied to the case where the rhythm sound is generated.

Generally, when a rhythm sound is generated, each rhythm sound is assigned to each pitch, for example, the snare drum is assigned to the “C3” pitch and the ride cymbal is assigned to the “G3” pitch. The assigned rhythm is generated based on the pronunciation instruction for the pitch. At this time, you may change the assigned content of the rhythm sound or set the volume of the rhythm sound.In this case, select the pitch and then select the rhythm sound to be assigned to that pitch, or There are two conceivable setting methods: when setting the volume at, and when selecting the rhythm sound, then selecting the pitch to which the rhythm sound should be assigned, or when setting the volume of the rhythm sound. When the present invention is applied to the generation of such a rhythm sound, the operation of the test sound generation instruction button causes the rhythm sound currently assigned to the currently selected pitch in the former case. In the latter case, the currently selected rhythm sound is generated.
