The normal mode is a mode in which a performance (sounding of a musical piece corresponding to the user performance) is performed using the keyboard 5A while performing a desired automatic performance (accompaniment), and the pattern mode is such that the user can freely perform various patterns from the keyboard 5A. In this mode, automatic performance is performed while selecting a section, a part, and a part. A play start (“PLAY”) switch 105 is a switch for instructing start of reproduction of the selected pattern data, and a place top (“STOP”) switch 106 is for instructing stop of reproduction of the selected pattern data. Switch. The parameter setting switch 104 is a switch for setting various parameters, and will be described later in detail.

In the middle of the panel, a pattern selection switch 1 is provided.
The display of the switch functions of the section selection switch 101, the reproduction part selection switch 102, and the control part selection switch 103 is arranged corresponding to each key of the keyboard 5A together with the LED 4A. And the keyboard 5A at the bottom of the panel
Is arranged. The function display of each selection switch arranged in the middle part of the panel is arranged corresponding to a predetermined key (white key and black key) of the keyboard 5A arranged in the lower part of the panel for each content that can be set by each switch. Is done. That is, the pattern selection switch 100 and the section selection switch 1
01, the reproduction part selection switch 102 and the control part selection switch 103 are operated by depressing the corresponding keys on the keyboard 5A. The pattern selection switch 100 is provided for each type of pattern data (in this embodiment,
PATTERN1 to PATTERN10) are provided with selection switches corresponding to a predetermined range of keys (white keys and black keys) on the keyboard 5A, and when a desired key is depressed, any one of the corresponding patterns is pressed. The data is selected. For example, pressing the white key on the far right
"TTERN10" is selected, and when the rightmost black key is pressed, "PATTERN9" is selected. The section selection switch 101 is a switch corresponding to each section (in this embodiment, SECTION1 to SECTION10) which is the content of the pattern data selected by the pattern selection switch 100. Each selection switch is a key within a predetermined range of the keyboard 5A. (White key and black key), and by pressing a desired key among them, any corresponding section data is selected. That is, the section data that can be selected by the section selection switch 101 is in accordance with the content of the selected pattern data. For example, when one pattern data as shown in FIG. 2 is composed of ten section data, the sections that can be selected by the section selection switch are the sections 1 to 10
And keys corresponding to this are assigned as the section selection switch 101.

The reproduction part selection switch 102 is a switch for selecting a part to be reproduced (that is, a sound generation state), and includes a “SECTION” switch, a composite selection switch, a part-specific selection switch, and a “TOGGLE” switch. I can. The part-specific selection switch is a switch that can select a part for each part data included in the section data. That is, the parts that can be selected by the part-specific selection switches are in accordance with the contents of the selected section data. For example, when one section data is composed of eight parts as shown in FIG. 2 described above, the part that can be selected by the part-specific selection switch is any of parts 1 to 8. Only the corresponding keys are assigned as part-specific selection switches. In this embodiment, a “BASS” switch for selecting a bass part, a “KICK” switch for selecting a bass drum part, a “SNARE” switch for selecting a snare drum part, and a first phrase part are provided. "PHRASE1" switch to select, "HI-HAT" to select hi-hat cymbal part

"C" switch, "P" to select the third phrase part
The “HRASE3” switch corresponds to the part-specific selection switch.
By operating the part-specific selection switch, it is possible to set a selected part and a non-selected part for each part. That is, each time the desired part-specific selection switch is operated once, the part is inverted and set to an on state (selected part) in which the part is selected as a reproduction part or an off state (non-selected part) not selected. For example, if all of the parts are set as selected parts,
When the "E" switch is operated, only the snare drum part becomes a non-selected part and only that part is muted. In this way, in each part selection switch, only the part corresponding to the operated switch is turned on / off.
Inverts the off setting and does not switch the on / off setting for the other parts. The part-specific selection switch determines in advance which part to designate (for example, the “BASS” switch is part 1).

The "TOGGLE" switch is a switch for inverting and switching all of the reproduction part and the non-reproduction part at once. When the "TOGGLE" switch is operated, the current reproduction part of all the parts of the currently selected section is operated. Is set to the non-playback part, and the current non-playback part is collectively inverted to the playback part. That is, "TOGGLE"
When the switch is operated once, the playback status of each part is reversed at once, and the parts that were in the playback state before the “TOGGLE” switch was turned into the non-playback state, and the parts that were in the non-playback state before the “TOGGLE” switch was operated Is in the playback state. The composite selection switch is a switch for simultaneously selecting a plurality of predetermined parts at once. In this embodiment, “BASS + KICK”
The switch “KICK + HI-HAT” switch corresponds to the composite selection switch. For example, when a “BASS + KICK” switch is operated, a bass part (“BASS” switch) and a bass drum part (“KICK” switch) are set as selected parts, and other parts are set as non-selected parts. That is,
Only the bass part and the bass drum part are in the playback state, and the other parts are in the non-playback state. "SECTIO
The "N" switch is a switch capable of selecting an optimum reproduction part suitable for the currently selected section. The optimal reproduction part is one or more predetermined parts that can optimally reproduce the performance of the section,
It is determined by referring to the optimal reproduction part table prepared in advance. Therefore, when the "SECTION" switch is operated, the parts according to the optimum reproduction part table are set to the reproduction state, and all other parts are set to the non-reproduction state. Thus, in this embodiment,
"TOGGLE" switch, composite selection switch, "SECTION"
According to the operation of each switch of the switch, the reproduction state / non-reproduction state of a plurality of parts can be simultaneously and collectively switched. By doing so, the reproduction state of the automatic performance changes in response to the intuitive operation of the user, so that the user can enjoy the automatic performance of a multi-part configuration that is rich in changes.

The control part selection switch 103 is a switch for selecting a part to be subjected to various controls such as changing a tone to be generated, and is composed of a "SECTION" switch, a composite selection switch, and a part-specific selection switch. . The contents that can be set by these switches are the same as those described for the playback part selection switch, and thus description thereof will be omitted.

The parameter setting switch 104 is a switch for setting various control parameters for the part selected by the control part selection switch 103. In this embodiment, a "VOLUME" switch, a "CUT-OFF" switch, and a "RES
The "ONANCE" switch is shown as an example. The “VOLUME” switch is a switch for setting a parameter for controlling the playback volume of the selected part. For example, turning the switch to the right increases the volume, and turning it to the left decreases the volume. The “CUT-OFF” switch is a switch for setting a parameter for controlling the filter cutoff frequency of the selected part. For example, turning the switch to the right shifts the filter cutoff frequency to the higher side and makes the reproduced tone a brighter tone, and turning it to the left shifts the filter cutoff frequency to the lower side and reproduces the tone. It has a muffled tone. "RESONANC
The “E” switch controls the resonance characteristics of the tone control filter of the selected part (controls the level magnitude near the filter cutoff frequency, ie, “Q”).
This is a switch for setting parameters. For example,
Turning the switch to the right increases the “Q” of the filter, and turning it to the left decreases the “Q”. The parameter set by the parameter setting switch is a parameter common to all parts selected by the control part selection switch 103.

The above-described pattern selection switch 100
A light emitting diode 4A (shown as a square in the figure) is provided near a key corresponding to the section selection switch 101, the reproduction part selection switch 102, and the part selection switch in the control part selection switch 103. The light emitting diode 4A is turned on or off according to the operation of each switch, so that the user can know the selected content. Further, the light emitting diodes 4A are arranged with different colors for each corresponding key color (that is, white key and black key) so that the user can see at a glance which key corresponds to which switch. Has become.

In this example, only the performance data of the part selected according to the reproduction part selection operator 102 is stored in the tone generator (T
G) Supply to 114. Playback part selection operator 102
When the "SECTION" switch is operated at the time of selection of the reproduction part by the reproduction part selector 113, the reproduction part selector 113 refers to the optimum reproduction part table T1 and outputs only the performance data of the predetermined part according to the table T1. TG) 114. The optimum reproduction part table T1 is a table in which the optimum reproduction part is recorded for each section data of each pattern data. By reproducing the parts according to the table T1, the respective parts are appropriately harmonized. The music can be reproduced in a state where the music is played. Tone generator (T
G) 114 reads the waveform data corresponding to the performance data of the part supplied from the reproduction part selector 113 from the waveform data memory 115, and
To 16. That is, the tone generator (TG) 114 executes the musical tone waveform generation processing according to the supplied performance data of the part in parallel, and supplies the generated musical tone waveform data to the control part selector 116. In the control part selector 116, a tone generator (TG)
The tone waveform data supplied from 114 is divided into tone waveform data of a predetermined part designated by the control part selection operator 103 and tone waveform data of other parts, and The tone waveform data of the part is supplied to the filter 117, and the tone waveform data of the other parts is supplied to the mixer 118. When the control part is selected by the control part selection operator 103,
When the “SECTION” switch is operated, the control part selector 116 refers to the optimum control part table T2 and supplies only the performance data of a predetermined part to the filter 117 according to the table T2. The optimum control part table T2 is a table in which the optimum control part is recorded for each section data of each pattern data, and by controlling the parts according to the table T2, each part is efficiently and appropriately determined.

That is, various buffers and flags used in the process are initialized (that is, cleared). In this embodiment, the contents of the pattern buffer, section buffer, playback part buffer, control part buffer, parameter buffer, or RUN flag are set to initial values. The pattern buffer stores the number of the currently selected pattern. Similarly, the section buffer stores the number of the currently selected section. The reproduction part buffer or control part buffer stores information on a part to be not reproduced (or not controlled) and a part to be reproduced (or controlled). The parameter buffer stores the contents of the currently set parameters. Therefore, in this initial configuration,
For example, the contents of the pattern buffer and section buffer are set to "pattern 1" and "section 1", and the contents of the reproduction part buffer and control part buffer are set to "all part reproduction".
A setting such as "no parameter setting" is made for the contents of the parameter buffer in "all part control". In addition, the RUN flag is set to “0” (in this embodiment, the RUN flag = “1” indicates that the pattern data is in the reproduction state, and the RUN flag = [0] indicates that the pattern data is in the non-reproduction state. ).

In step S2, each process from step S3 to step S7 is performed according to the contents of the various switches operated. If the pattern is selected in step S2, that is, if the pattern data is selected by operating the pattern selection switch 100, the process of step S3 is performed. In step S3, the selected pattern number is stored in the pattern buffer. For example, a pattern number according to the selected pattern data is stored in the pattern buffer, such as "pattern 1" when "PATTERN1" is selected, and "pattern 2" when "PATTERN2" is selected. . Then, various displays are changed according to the selected pattern data. For example, “PATT” of the pattern selection switch 100
The display of the light emitting diode (LED) 4A arranged above the keys corresponding to “RN1” to “PATTERN10” is changed. That is, the light emitting diode (LED) 4A corresponding to the selected pattern is turned on, and the light emitting diode (LED) 4A corresponding to the other pattern is turned off. Of course, other than this, it goes without saying that processing such as changing the data content displayed on the liquid crystal screen 7A to the content of the selected pattern data is performed. The RUN flag is set to “1” by operating the pattern selection switch 100. That is, when the keys of the keyboard 5A corresponding to the pattern selection switch 100 are sequentially operated, the reproduction is started according to the operation. In this way, by starting the reproduction in accordance with the pattern selection operation, the user can intuitively perform the reproduction using the keyboard 5A as if he were performing. At this time, a timing counter for counting an interrupt timing at the time of performing an interrupt process to be described later is reset to mute a tone being reproduced. For example, if the contents of the pattern buffer, section buffer, and playback part buffer are set to “pattern 1”, “section 1”, and “play all parts” as the initial settings, and “PATTERN2” is selected, “pattern 2” and “section 1” "All parts are reproduced", and the reproduced pattern 1 is muted and the pattern 2 is reproduced from the beginning.

If the section has been selected in step S2, that is, the section selection switch 1
When the predetermined section data is selected from the pattern data by the operation of 01, the process of step S4 is performed. The processing in step S4 is performed in step S3 described above.
A process similar to the process of is performed. That is, the selected section number is stored in the section buffer. Various displays are changed according to the selected pattern data. For example, "SECTION1"
The display of the light emitting diode (LED) 4A arranged above the key corresponding to “SECTION 10” is changed. That is,
The light emitting diode (LE) corresponding to the selected section
D) 4A is turned on, and the light emitting diodes (LED) 4A corresponding to the other sections are turned off. By operating the section selection switch 101, "1" is set to the RUN flag. That is, when the keys of the keyboard 5A corresponding to the section selection switch 101 are sequentially operated, the reproduction is started according to the operation. In this way, by starting the reproduction in accordance with the section selection operation, the user can intuitively perform the reproduction using the keyboard 5A as if performing. At this time, a timing counter for counting an interrupt timing at the time of performing an interrupt process to be described later is reset to mute a tone being reproduced. For example, as an initial setting, the contents of the pattern buffer, the section buffer, and the reproduction part buffer are set to "pattern 1"
If “SECTION2” is selected when “All Parts” is selected, “Pattern 1”, “Section 2” and “All Parts” will be played. Play section 2 of pattern 1.

If the reproduction part has been selected in step S2, that is, the reproduction part selection switch 1
If a predetermined part is selected by the operation of 02, the process of step S5 is performed. In step S5, the content of the playback part buffer is updated according to the selected content of the playback part. The reproduction part buffer stores the current reproduction state (that is, “reproduction” or “non-reproduction”) for each part. For example, if the composite selection switch “KICK + HI-HAT” switch is selected,
The bass drum part and the hi-hat cymbal part are stored as “play”, and all other parts are stored as “non-play”. When the "TOGGLE" switch is operated, all the parts currently being reproduced are stored as "non-reproduction", and all the parts which are currently non-reproduction are stored as "reproduction". When the “SECTION” switch is operated,
Only the part corresponding to the section selected according to the optimal reproduction part table T1 is stored as "reproduction",
All other parts are stored as "non-reproduction". Thus, in updating the contents of the reproduction part buffer, the contents are rewritten according to the above operation. Then, in "interrupt processing" described later, it is determined which part is to be reproduced at present according to the contents of the reproduction part buffer, and only the part stored as "reproduction" is reproduced. Subsequently, various displays are changed according to the selected reproduction part. For example, the display of the light emitting diode (LED) 4A arranged above the key corresponding to the part selection switch in the reproduction part selection switch 102 is changed.
That is, the light emitting diode (LED) 4A corresponding to the selected part is turned on, and the light emitting diodes (LED) 4A corresponding to the other parts are turned off. In the process of step S5, the reproduction is stopped (that is, the pattern selection switch 100 or the section selection switch 10).
1 or play start switch ("PLAY") 105
However, even if the playback part selection switch 102 is operated to select a playback part, the playback is not started. That is, the above-described step S
Unlike step 3 and step S4, the RUN flag is not set.

Here, the operation at the time of the reproduction part selecting operation will be briefly described based on a specific example. When the reproduction is started in an initial setting state such as "pattern 1", "section 1", "all part reproduction", reproduction (sound generation) of all parts is started. When the "SNARE" switch is operated once during playback of all parts, only the snare drum part is muted, and the other parts remain reproduced (produced). When the "SNARE" switch is operated once more, the reproduction of the snare drum part is started, and the sound is produced together with the other parts. While playing all parts, set the "SNARE" switch to 1
After performing this operation the next time, operate the “PERC” switch.
The tom tom part is also muted in addition to the snare drum part. Next, snare drum part and tom tom
When the "TOGGLE" switch is operated once while the parts are muted, only the snare drum part and the tom tom part start playing (sound), and all other parts are muted. When the "TOGGLE" switch is operated once more, only the snare drum part and the tom tom part are muted, and all other parts are started to be reproduced (produced). When the snare drum part and the tom tom part are muted, if the “KICK + HI-HAT” switch is operated once, only the bass drum part and the hi-hat cymbal part will start playing (sounding). Then, all other parts are muted. If the "HI-HAT" switch is operated once more in this state, only the sound of the hi-hat cymbal part is muted, and the other parts remain reproduced (produced). That is, the bass / drum part which has been reproduced (produced) by operating the “KICK + HI-HAT” switch is muted, and the hi-hat cymbal part remains reproduced (produced). When the "SECTION" switch is operated while any part is being reproduced, only the part corresponding to the section already selected according to the optimum reproduction part table T1 is reproduced (produced).
The other parts are muted. For example, if the bass part, the bass drum part, and each phrase part are optimal reproduction parts, only these parts are reproduced (produced), and all other parts are muted.
After operating this “SECTION” switch (that is,
If the "SNARE" switch is operated on the part, the bass drum part and each phrase part are reproduced, only the snare drum part is reproduced (produced). After operating the "SECTION" switch (that is, the bass part, bass drum part and each phrase part are being played), operating the "TOGGLE" switch allows the bass part, bass drum part and each phrase to be played. -The part is muted and the other part is played (produced). After operating the "SECTION" switch (that is, the bass part, bass drum part and each phrase part are being played), operating the "KICK + HI-HAT" switch enables the bass drum part and hi-hat cymbal part. Only the sound is reproduced (pronounced). In the above-described example, when the "SNARE" switch is operated after the "SECTION" switch is operated, only the snare drum part is reproduced (produced). However, the present invention is not limited to this. That is, the part selected by operating the “SECTION” switch (in the above example, the bass part, the bass drum part, and each phrase part) is added to a part-specific selection switch (in the above example, the “SNARE” switch). ) May be added to play (produce) the part (snare drum part in the above example) selected by the above operation.

Returning to FIG. 5, when a control part is selected in step S2, that is, when a predetermined part to be controlled is selected from section data by operating the control part selection switch 103, step S6 is performed. Is performed. In step S6, the content of the control part buffer is updated according to the selected content of the control part. The control part buffer stores the current control state (that is, “controllable” or “controllable”) for each part. For example, when the composite selection switch “KICK + HI-HAT” is selected, the bass drum part and the hi-hat cymbal part are stored as “controllable”, and all other parts are “controllable”.
Is stored. When the "SECTION" switch is operated, only the part corresponding to the section selected according to the optimum control part table T2 is stored as "controllable", and all other parts are stored as "control impossible". You. As described above, in updating the contents of the control part buffer, the contents are rewritten according to the above operation. Then, in "interrupt processing" described later, it is determined which part is currently controlled according to the content of the control part buffer, and only the part stored as "controllable" is controlled according to the content of the parameter. . Subsequently, various displays are changed according to the selected control part. For example, the display of the light emitting diode (LED) 4A arranged above the key corresponding to the part selection switch in the control part selection switch 103 is changed. That is, the light emitting diode (LED) 4A corresponding to the selected part
Is turned on, and the light emitting diodes (LEDs) 4A corresponding to the other parts are turned off. Also in the processing of step S6, the control part selection switch 103 is stopped during reproduction stop (that is, when the pattern selection switch 100, section selection switch 101, play start switch ("PLAY") 105, etc. are not operated).
Even if the control part is selected by operating, the reproduction is not started. That is, unlike the above-described steps S3 and S4, the RUN flag is not set.

If the parameter has been set in step S2, that is, the parameter setting switch 1
If the parameter has been set by the operation of step 04, the process of step S7 is performed. In step S7, the contents of the parameter buffer are updated according to the parameter setting contents. According to the contents of the parameter buffer, various controls are performed on the part stored as “controllable” in “interrupt processing” described later.

In step S8, "other processing" is performed. This “other processing” includes, for example, the start of reproduction of pattern data by operation of the play start (“PLAY”) switch 105 and the place top (“STOP”) switch 1.
Processing such as stopping the reproduction of the pattern data by the operation 06 or changing the set tempo value is performed. Step S9
Then, it is determined whether the pattern mode has ended. If the pattern mode has not been completed (N in step S9)
O), the process returns to step S2, and the above processes are repeatedly executed. On the other hand, if the pattern mode has ended (YES in step S9), the process ends. That is, the automatic performance device returns to the normal mode.

Next, "interrupt processing" will be described.
FIG. 6 is a flowchart showing one embodiment of the "interrupt processing" executed by the CPU 1 in the above-mentioned automatic performance apparatus. That is, this "interrupt processing" is executed by the CPU 1 in an interrupted manner at predetermined timings in synchronization with the operation clock from the timer 1A. In step S11,
It is determined whether or not the RUN flag is [1]. RUN
If the flag is not "1" (N in step S11)
O), the process ends. If the RUN flag is "1" (YES in step S11), an event to be reproduced at the current timing is transmitted to the tone generator (TG) 114 (step S12). That is, the performance data to be read is determined according to the contents of the pattern buffer, the section buffer, and the reproduction part buffer, and the event at the current timing in the performance data is read and the tone generator (TG) 114 is read.
Send to Next, it is determined whether or not the determined performance data is performance data of the control part (step S1).
3). If it is a control part (Y in step S13)
ES), a waveform corresponding to the contents of the event transmitted to the tone generator (TG) 114 and the contents of the parameter buffer is generated (step S14). That is, the tone waveform data is changed by the filter 117. On the other hand, if it is not a control part (N in step S13)
O), generate a waveform corresponding to the content of the event transmitted to the tone generator (TG) 114 (step S1)
5). That is, the tone waveform data is not changed by the filter 117. The waveforms of all the parts including the waveforms generated in this way are synthesized to reproduce a musical tone (step S16). At this time, pitch conversion based on the contents of the chord sequence data (chord progression data) is performed on each part of phrases 1 to 3. That is, the pitch of each part of the phrase 1 to the phrase 3 is converted in accordance with the chord component sound following the chord progression. Then, a timing counter value for measuring a predetermined time is incremented (step S17). In step S18, it is determined whether or not the length of two measures has been completed (or whether the end data has been read). That is, it is determined whether the timing counter value is equal to a predetermined value (or whether the performance data has ended). When the length of two measures is completed (or the end data is read) (step S
18)), the performance data read position is returned to the beginning. That is, when the interruption processing is performed again, the performance data can be repeatedly reproduced, and the processing ends. The length of two measures has not ended yet (or the end data has not been read)
In this case (NO in step S18), the process ends in that state. Note that the "two measures" in step S18 described above is an example, and the present invention is not limited to this. For example, the user may be able to set appropriately such as “1 bar” or “4 bars”.

By operating the composite selection switch,
Although an example has been shown in which a plurality of predetermined parts corresponding to the switch are in a reproduction state and the other parts are in a non-reproduction state, the present invention is not limited to this. For example, by operating the composite selection switch, it may be instructed to add a part corresponding to the switch to the part currently in the reproduction state and reproduce the part. In addition, each time the composite selection switch is operated once, the part corresponding to the switch may be set to be alternately inverted between the reproduction state and the non-reproduction state. Further, the user may be allowed to freely create a combination of a plurality of parts corresponding to one composite selection switch. That is, the user may freely set the parts that can be set to the reproduction state (or the non-reproduction state) by the composite selection switch. In this case, a new composite selection switch created by the user may be assigned to an empty key of the keyboard 5A that is not used as a switch for selecting a part.
The "SECTION" switch may be used to select a reproduction (or control) part suitable for both the selected pattern and section, in addition to selecting a reproduction (or control) part corresponding to the section. . The parameter values that can be set by the parameter setting switch 104 include various control parameters of an envelope, a sound control parameter (for example, a timing correction parameter, a velocity correction parameter, and the like) other than volume, a filter cutoff frequency, and resonance, in addition to performance control. , Pitch correction parameter). The parameters set by the parameter setting switch 104 are not limited to those commonly set for all the parts selected by the control part selection switch 103, and the parameters can be separately set for each of the selected parts. It may be. For example, control part selection switch 1
03 so that only one selectable part can be selected, the parameters are set for the selected part once using the parameter setting switch 104, and the setting contents are stored in the parameter buffer for each part. To memorize. Of course, even in such a case, it is needless to say that parameters can be collectively set for a plurality of parts by using a composite selection switch or a “SECTION” switch.

In the above example, the part selected by the reproduction part selection switch 102 and the control part selection switch 1
Although the part selected in 03 is not related, it may be related. For example, if only the part in the reproduction state can be selected by the control part selection switch 103, the user can enjoy a variety of parameter settings while checking the reproduction state. In the above-described example, the keyboard 5A can be used as the operator 6A, and the selection of the pattern, section, playback part, and control part can be performed by pressing a predetermined key of the keyboard 5A. Needless to say, a dedicated switch may be provided for each switch function, or a soft switch for performing a selection operation by operating a pointer on a display by a mouse operation or the like may be used. In the case where the timbre name and the part number are not previously associated with each other in the pattern data, the timbre name is selected with reference to the timbre name of the performance data (that is, the timbre data of each part recorded in the performance data). May be determined.

When the automatic musical instrument incorporating the control part selecting device according to the present embodiment is applied to an electronic musical instrument, the electronic musical instrument is not limited to a keyboard musical instrument, but may be a stringed instrument, a wind instrument, or a percussion instrument. May be. In such a case, the sound source device, the automatic performance device, and the like are not limited to those built in one electronic musical instrument main body, but each device is separately configured, and each device is configured using communication means such as a MIDI interface and various networks. It is needless to say that the present invention can be similarly applied to a configuration configured to connect. Further, the configuration may be a configuration of a personal computer and application software. In this case, the processing program may be supplied from a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, or may be supplied via a network. In addition, karaoke devices and game devices,
Or you may apply to portable communication terminals, such as a mobile telephone, an automatic performance piano, etc.

The performance data has a format of “event + absolute time” in which the event occurrence time is represented by an absolute time in a song or a bar, and the event occurrence time is the time from the immediately preceding event. "Event +
“Relative time” format, “pitch (rest) + note length” that represents performance data in note pitch and note length or rest and rest length
Any type, such as a “solid” type, in which a memory area is reserved for each performance minimum resolution and events are stored in a memory area corresponding to the time when a performance event occurs, . When performance data for a plurality of channels exists, a format in which data of a plurality of channels are mixed may be used, or a format in which data of each channel is separated for each track may be used. Further, the processing method of the performance data includes a method of changing the processing cycle according to the set tempo, a method of changing the value of the timing data during automatic performance according to the set tempo while the processing cycle is constant, and a processing cycle. May be any method such as changing the counting method of timing data in the performance data in accordance with the tempo in a single process. Further, on the memory, time-series performance data may be stored in a continuous area, or performance data scattered and stored in discrete areas may be separately managed as continuous data. Good. That is, it is only necessary that the performance data can be managed as time-series continuous performance data, and it does not matter whether the performance data is continuously stored in the memory.

The effect that the user can enjoy the game with a simple operation can be obtained. In addition, multiple parts can be controlled simultaneously according to the operation of the composite selection switch and the “SECTION” switch, allowing automatic performance of multiple parts with various controls added. The effect is obtained that the operation can be appropriately performed by a simple operation.
