For example, as an automatic accompaniment device, musical tone data is read out from automatic accompaniment pattern data (performance information) stored in advance in a memory, and elements such as tone generation timing, gate time (pronunciation duration) or velocity (volume) of the tone data are read. Some of them generate automatic accompaniment sounds based on the changed data. Thereby, an accompaniment having a different atmosphere from that in the case of reproducing the original pattern data as it is can be obtained without changing the pattern data itself. In other words, the technique of performing only with pattern data is a monotonous playback performance that is determined by the pattern data. However, when the performance information is converted as described above, a subtle groove or groove feeling ( The expression is like a song when performing by a musician).

  Hereinafter, embodiments of the present invention will be described. The outline of this embodiment is as follows. In the sequencer with built-in tone generator, the song data (music performance information) is played when the “normal mode” is selected, and the song is automatically played. The pattern data (accompaniment pattern performance information) is played when the “pattern mode” is selected. To perform automatic accompaniment. In the “pattern mode”, the pattern data is converted with the change pattern data (change information), so that the automatic accompaniment can be changed and various performances can be performed. Therefore, hereinafter, the “pattern mode” automatic accompaniment will be mainly described. Each of the pattern data and the change pattern data has a length of 2 bars (the number of beats is 4/4 time), and one section obtained by dividing the time length of the two bars by 16 is called “grid”. That is, one grid corresponds to one section for every eighth note unit.

  In this embodiment, pitch (pitch information), tone generation timing, gate time, and velocity are changed as elements of the musical tone data of the pattern data, and the changed pattern data is changed in time series corresponding to each element. It consists of a quantity (change data). Furthermore, the pattern data is composed of a plurality of tracks corresponding to a plurality of parts of accompaniment, and the change pattern data is composed of a plurality of tracks so as to correspond to each track of the pattern data (excluding the rhythm track). Each change amount can be set and corrected in units of grids for each track.

  FIG. 1 is a block diagram showing a sequencer with built-in tone generator to which the performance information conversion apparatus of the present invention is applied. The CPU 1 controls the entire sequencer using the working area of the RAM 3 based on a control program stored in the ROM 2. . The RAM 3 stores song data, pattern data, change pattern data, and the like. The RAM 3 is provided with a change amount buffer for storing the change amount for each track of the change pattern data and for each grid. The RAM 3 is backed up by a battery, and song data, pattern data, and change pattern data are stored even when the power is turned off.

  The CPU 1 sets the tempo information stored in the pattern data or the input designated tempo information in the timer 4, the timer 4 generates a clock signal (tempo clock) according to the set tempo, and the CPU 1 Interrupt processing is performed for each clock signal to perform automatic accompaniment and automatic performance processing. The clock signal has 48 clocks corresponding to one beat of a quarter note, and one bar length in ¼ beat is 192 clocks.

  In the automatic accompaniment process, the timing is determined by counting the clock signal, the tone data and the change amount at the current timing are read from the pattern data and the changed pattern data, respectively, and the change is made according to the change amount of each element of the tone data. The changed data is output to the sound source circuit 5 together with note-on / note-off.

  The tone generator circuit 5 is capable of simultaneously generating sound on a plurality of channels, and generates a tone signal of a predetermined tone color (tone set in the pattern data track) based on pitch data, note-on and velocity set by the CPU 1. To do. Various effects are applied to the musical sound signal generated by the sound source circuit 5 by the effect circuit 6, and a musical sound is generated by the sound system 100. Also, by setting note-off to the sound generation channel, the musical sound signal is attenuated or stopped and muted.

  As will be described later, the operation element 7 includes various switches arranged on the operation panel. The CPU 1 captures input data of the various switches of the operation element 7 through the detection circuit 7a and performs various processes according to the switch operation. Do.

  The display 8 is composed of a liquid crystal panel or the like disposed on the operation panel, and various displays are performed on the display 8 by the CPU 1 outputting display data to the display circuit 8a.

  The external storage device 9 is a hard disk device (HDD), a floppy (trademark) disk device (FDD), a CD-ROM device, a magneto-optical disk (MO) device, a digital multi-purpose disk (DVD) device, or the like. It can also be used for inputting and storing various data such as. A MIDI interface (I / F) 10 is used to exchange various data such as pattern data and song data with an external MIDI device. A communication interface 11 is connected to a communication network 200 to be used as a server computer. Is receiving distribution of various data such as pattern data and song data.

  FIG. 2 is a diagram showing an operation panel, mainly showing a part related to setting of a pitch change amount, and omitting parts related to other elements (sound generation timing, gate time, velocity). The operator 7 includes a mode switch 71 for switching between “normal mode” and “pattern mode”, a pitch bend knob 72 for inputting a pitch change amount, a play switch 73 for instructing reproduction of automatic accompaniment and automatic performance, automatic accompaniment and automatic performance, Are provided with a stop switch 74 for instructing to stop and a plurality of grid selection switches 75 for selecting a grid. In addition, a switch (not shown) for inputting a change amount of other elements other than the pitch is also provided. The grid selection switch 75 is shared to select a grid for each element.

  By the way, in a sequencer or the like, a keyboard-like keyboard arranged in the same way as the white and black keys of the keyboard is used for step input and real-time input of song data and pattern data, and for use as pad keys when inputting rhythm parts. Some have a switch. The grid selection switch 75 of this embodiment is assigned to 16 switches corresponding to the white keys of the keyboard-like switches. In FIG. 2, the switch corresponding to the black key is not shown.

  Further, for example, when inputting the change amount of the pitch in the “pattern mode”, the display 8 displays as shown in FIG. That is, the pattern name of the currently selected pattern data is displayed as “users1” of “Pattern Name / users1”, and the track number of the currently selected track of the pattern data is “Track Number / 3rd”. It is displayed as “3rd”. Also, 16 grids corresponding to the length of the pattern data are displayed in a grid frame F consisting of 16 grids, and the setting contents of the change amount of the pitch of the currently selected track are displayed in the grid frame F. Is done.

  That is, the change amount data of the pitch is read from the change amount buffer of the RAM 3 from the track corresponding to the selected track of the pattern data (the track of the change pattern data), and the change of the pitch is designated. A triangle indicating the amount of pitch change is displayed on the grid corresponding to the grid. One triangle mark corresponds to a semitone, an upright triangle mark indicates that the pitch is changed higher, and an inverted triangle mark indicates that the pitch is changed lower. Also, the white triangle mark indicates the change amount that has been set so far, and the black triangle mark indicates the change amount that has been set this time. Further, the grid selected to be set this time by the grid selection switch 75 is displayed in halftone dots (cells indicated by 1G, 3G, 4G). For other elements other than the pitch, a pattern indicating the grid frame and the change amount is independently displayed in the display 8.

  It should be noted that the basic processing is the same regardless of the data to be handled in both the case of changing the pitch and the case of changing other elements. Therefore, in the following description, the change of the pitch will be mainly described as an example.

  FIG. 3 is a flowchart of the pitch change amount setting process in the embodiment, which is an example of a performance information conversion control program according to the present invention. FIG. 4 is a flowchart of the reproduction interruption process, and the operation of the embodiment will be described based on each flowchart. Although the description of the main flow processing is omitted, the pitch change amount setting processing in FIG. 3 is a subroutine processing when the mode switch 71 is switched to “pattern mode” in the main flow processing. .

  In these processes, a counter register set in the RAM 3 is used to indicate the reading position of pattern data and change pattern data (position indicated by the clock value in two bars). In other words, this counter register is incremented every time a reproduction interrupt process occurs, and is reset when two bars (for 192 clocks) are counted. The count value at the time when the automatic accompaniment stop instruction is given is held in another register of the RAM 3, and when the automatic accompaniment start instruction is given again, the held count value is set in the counter register. As a result, the reading position is set.

  In the pitch change setting process of FIG. 3, first, pattern data selection and track selection processing are performed in step S1, and the pattern number of the selected pattern data, the track number of the track, and the corresponding track are displayed on the display 8. Display according to the selected content, such as displaying the grid frame F to be set and the pitch change amount setting content (triangle mark) in the grid frame F.

  Next, in step S2, it is determined whether or not the grid selection switch 75 is operated. If there is no operation, the process proceeds to step S4. If there is an operation, display of the grid corresponding to the grid selection switch 75 operated in step S3 is displayed. Change to step S4. This change in the grid display means that if the grid corresponding to the operated grid selection switch 75 has not been selected at that time, it is assumed that it has been newly selected, and the dot in the grid of the grid frame F is displayed (see FIG. 2), if the grid has already been selected, the selection is canceled and the grid in the grid frame F is switched from halftone dot display to non-halftone dot display.

  Next, in step S4, it is determined whether or not the pitch bend knob 72 is operated. If there is no operation, the process proceeds to step S6. If there is an operation, information on the change amount of the change buffer corresponding to the selected grid is obtained in step S5. While rewriting according to the operation amount of the pitch bend knob 72, the display of the corresponding setting content (triangle mark) is updated in the grid being selected in the grid frame F, and the process proceeds to step S6.

  In step S6, it is determined whether or not there is a reproduction instruction with the play switch 73. If there is no reproduction instruction, the process proceeds to step S8. If there is a reproduction instruction, the reading position of the pattern data and changed pattern data is set in the counter register in step S7. At the same time, the RUN flag set in the RAM 3 is set to "1" and the process proceeds to step S8. In the above setting of the read position, the first playback instruction after power-on is set at the top position of the pattern data, and in the playback instruction after the previous automatic accompaniment is stopped, the automatic accompaniment is stopped as described above. Set to the position of.

  In step S8, it is determined whether or not there is a stop instruction with the stop switch 74. If there is no stop instruction, the process proceeds to step S10. If there is a stop instruction, all the sounds that are sounding are muted in step S9 and the RUN flag is set. Set to “0”, further store the current read position (save the value of the counter register), and proceed to step S10.

  In step S10, it is determined whether or not there has been a mode switching instruction by operating the mode switch 71. If there is no switching instruction, the process returns to step S2 and the same processing is repeated. If there is a mode switching instruction, the sound is generated in step S11. All the sounds are muted and the RUN flag is set to “0” to complete the pitch change amount setting process (return to the original routine).

  As a result of the above processing, at any time in the “pattern mode”, one or a plurality of grids can be arbitrarily selected by simply operating the grid selection switch 75 for the selected track, and the pitch bend knob 72 can be used to select the selected grid. The amount of pitch change can be set. Further, when the play switch 73 gives an automatic accompaniment reproduction instruction, the RUN flag is set to “1”, so that automatic accompaniment according to the pitch change amount of each grid is performed by the reproduction interruption process described below.

  The reproduction interruption process of FIG. 4 is started at a timing of 48 times per quarter note by the clock signal from the timer 4, and first, in step S21, whether or not “RUN = 1”, that is, the RUN flag is “1”. If RUN = 1, the process returns to the original routine. If RUN = 1, in step S22, at the current timing indicated by the count value of the counter register, The presence / absence of a sound / mute event is determined. If there is no sound / mute event, the process returns to the original routine. If there is a sound / mute event, the change amount buffer of the grid to which the current timing belongs is referenced in step S23.

  Next, in step S24, it is determined whether or not there is an effective pitch change amount (change amount other than “0”) in the change amount buffer. If there is a pitch change amount, the pitch data of the sounding event is changed according to the pitch change amount read in step S25 to obtain pitch data. In step S26, pitch data and note-on are output to the sound source 5 at the sounding event, and note-off is output to the sound source 5 at the mute event, and each of the sounding or mute event processing is performed and the counter register is output. Is updated (reset at the end of two bars) and returns to the original routine. Note that the sound generation or mute event processing is performed for each track.

  With the above processing, the pattern data is changed according to the pitch change amount and a musical tone is generated. This playback interrupt processing is started by the interrupt signal during the pitch change amount setting processing of FIG. If the pitch change amount is rewritten in this pitch change amount setting process, the automatic accompaniment reflects the rewritten pitch change amount. That is, since the pitch of the musical sound can be changed in real time during automatic accompaniment, various performances can be performed. In addition, since an arbitrary grid can be selected by the plurality of grid selection switches 75 corresponding to each grid, the change amount input operation can be performed very easily.

  FIG. 5 is a diagram conceptually showing an example of pattern performance, and corresponds to the case where the pitch change amount as shown in FIG. 2 is set. First, when the automatic accompaniment starts, the pitch is changed to a semitone in the first grid, and then the pitch is changed to a semitone in the third grid. Next, the fifth and seventh grids are changed to one tone and one and a half, respectively, and the second measure is entered. In the second measure, the pitch is changed to a semitone below the ninth grid, one pitch below the eleventh grid, and one half a pitch below the thirteenth grid. From the third measure, the pattern data and the changed pattern data are repeatedly reproduced. Thus, for example, if the pitch change amount is further increased by a semitone in the fifth grid during this automatic accompaniment before entering the fifth grid of the third bar, 1 is set in the fifth grid of the first bar. When the fifth grid of the third measure is played back, it is changed to one and a half tones. That is, it can be changed in real time even during automatic accompaniment.

  In the above processing, the reading position of the pattern data (and the changed pattern data) is saved when the automatic accompaniment is stopped, and is reproduced from the reading position at the start of the next automatic accompaniment. Alternatively, the saved reading position may be reset to the top by an operation of a cue switch or the like so that the pattern data can be reproduced from the top at the start of automatic accompaniment.

  Here, in the technology for changing such pattern data on the basis of the change information (change pattern data), there is no conventional technique for changing the pitch, and it is automatic by changing the pitch as in the above embodiment. The accompaniment melodies themselves can be changed, and a variety of performances can be performed. In the embodiment, the case where the pitch is changed in semitone units has been described. However, if the pitch is continuously changed, a so-called choking technique can be performed, and a wider variety of grooves can be obtained. it can.

  In the above description, the case where the pitch is changed has been described. However, the processing for changing the sound generation timing, the gate time, the velocity, and the like can be similarly performed. As a result, a sense of group and the like can be obtained, and various performances can be performed.

  Note that the sound generation timing and the mute timing determined by the sound generation timing and the gate time are determined according to each change amount of the sound generation timing and the gate time when determining the presence / absence of a sound generation / mute event at the current timing as in step S22. Judgment is made based on the changed timing.

  In addition, the change amount of the sounding timing is generally a small value compared to the note length. However, in order to perform the changing process even when the sounding timing is included in the previous grid due to the change, for example, When referring to the grid included in the current timing, the next grid is also referred to, and it is only necessary to determine whether there is a sound generation event at the current timing in the next grid.

  Note that the length or the number of grids of pattern data, change pattern data, grids, etc. is not limited to that of the embodiment. Also, in the embodiment, a grid can be selected even during automatic accompaniment, and the change amount can be set in real time for the selected grid. For example, the position of the current automatic accompaniment is displayed in the grid frame. For example, the change amount may be stored together with the timing data by the operation input at that time without selecting the grid, and the change pattern data may be created in real time together with the automatic accompaniment. Further, if it is possible to set for each song data or track whether or not to use the changed pattern data during pattern data reproduction, it is possible to enjoy a wider variety of performances.

  In the above embodiment, the case where the pattern data is changed has been described. However, the song data may be changed based on the changed pattern data. Further, for example, the change process may be performed in response to a performance by a user's keyboard or an arpeggio performance by an arpeggio function.

  In the above embodiment, the case where the pattern data and the change pattern data are stored in the RAM 3 and the performance information conversion control program is stored in the ROM 2 in advance has been described. However, the present invention is not limited to this. For example, pattern data, change pattern data, and a performance information conversion control program are recorded on a CD-ROM, and the performance information conversion control program is loaded from the CD-ROM device onto the hard disk (HD). Then, the CPU 1 develops this HD performance information conversion control program in the RAM 3, and controls the operation based on the program in the RAM 3 as in the above embodiment. Thereby, it is possible to cause the CPU to perform the same operation as when the performance information conversion control program is stored in the ROM 2. In this way, new installation, addition or version upgrade of the performance information conversion control program can be easily performed. Further, pattern data, change pattern data, and performance information conversion control program may be recorded on a floppy disk, a magnetic disk (MO), etc., and supplied to the RAM 3 or the hard disk.

  The communication interface 11 may be used to download the pattern data, song data, change pattern data, and performance information conversion control program. In this case, for example, it is connected to a communication network 200 such as a LAN (local area network), the Internet or a telephone line, and the accompaniment pattern data, song data, change pattern data and performance information are converted from the server computer via the communication network 200. By receiving the distribution of the control program, it is recorded on the hard disk and the download is completed.

  The present invention is not limited to the sound source built-in sequencer as in the above embodiment, but may be in the form of various electronic musical instruments such as a keyboard type, a stringed instrument type, a wind instrument type, and a percussion instrument type. In addition to an electronic musical instrument with a built-in tone generator circuit and automatic performance function, the tone generator, sequencer, effector, and the like are separate devices, and each device is connected using communication means such as MIDI or various networks. It may be something like this. In particular, in a keyboard-type electronic musical instrument, a dedicated switch is not required by assigning a keyboard as a grid selection switch.

  In the above embodiment, the present invention is applied to a sequencer. However, the performance information conversion apparatus of the present invention can be constituted by a personal computer and application software. In this case, the CPU of the personal computer performs control using the working area of the RAM, for example, by the OS installed in the hard disk, but the pattern data, song data, change pattern data or the like from the external storage device as in the above embodiment. The performance information conversion control program can be supplied as application software to a hard disk or the like, and the CPU can perform the same operation as in the above embodiment. In this case, a predetermined key of a keyboard for a personal computer may be used as a grid selection switch instead of the grid selection switch 75, and a change key may be input using, for example, a numeric keypad. Also, predetermined keys on the keyboard can be used for pattern data and track selection.

  It should be noted that the medium on which the performance information conversion control program is recorded as described above, that is, ROM, RAM, hard disk, CD-ROM, magneto-optical disk, DVD (digital multipurpose disk) or communication network server computer, etc. The storage device corresponds to a recording medium on which the performance information conversion control program according to claim 4 of the present invention is recorded.
