BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance data recording device for recording performance data for automatic performance.

0002

[Prior Art] Performance data recording devices that record performance data for automatic performance record the pitch and length of musical tones to be generated, as well as the timbre, effects, tempo, and rhythm of musical tones to be generated. Record setting data such as Since the above setting data is often changed at the same time at each turning point in a song, there is a system that collects combinations of setting data as registration data so that multiple pieces of registration data can be stored (Japanese Patent Laid-Open No. 62-175798). etc). In such an apparatus, all the setting data can be specified by simply recording registration number data specifying the registration data on the sequence track. For those who record performance data, there is no need to input a lot of setting data when changing settings, and it is sufficient to input registration number data.

0003

[Problem to be Solved by the Invention] However, if the settings of the registration data are changed after the performance data is recorded, or if this performance data is transferred to another automatic performance device with different registered registration data. In the case of copying, etc., the setting data read out based on the registration number data is completely different from the originally set contents, resulting in an unnatural performance. Furthermore, an automatic performance device without a registration function cannot read out setting data based on its registration number, and therefore has the disadvantage that it is impossible to perform.

[0004]Furthermore, there is a drawback that only a part of the setting data designated by the registration number data cannot be changed after recording the performance data. Furthermore, when the registration data specified by the registration number data is changed, there is a drawback that the settings of all parts specifying the same registration data are changed.

[0005] The present invention provides a performance data recording device that solves the above problem by recording all setting data of registration data on a sequence track when pre-stored registration data is specified. The purpose is to

[0006]

[Means for Solving the Problems] The present invention provides a registration data storage means for storing a plurality of sets of registration data each consisting of a plurality of setting data, and a registration number that specifies one set of the plurality of sets of registration data. a registration number data generation means for generating data; a performance data generation means for generating performance data;
reading means for reading registration data specified by the registration number data from the registration data storage means when the registration number data generation means generates the registration number data; and a registration data read out while recording the performance data. The present invention is characterized by comprising a recording means for individually recording setting data included in the data.

[0007]

[Operation] The performance data recording device of the present invention stores a plurality of sets of registration data, and can specify all of the registration data by generating registration number data that specifies the registration data. can. On the other hand, when writing this registration data to the recording means (sequence track), a plurality of pieces of setting data constituting the registration data are individually recorded, instead of the registration number data. This makes it easier to specify when recording performance data, to edit it after it has been recorded, and to ensure that even if the registration data is subsequently changed or copied to another automatic performance device, the setting data will be saved. It never changes.

FIG. 3 is a diagram showing the format of automatic performance data stored in the sequence track of the RAM 104. A plurality of sequence tracks configured in the illustrated format are set in the RAM 104. A header is provided at the beginning of the sequence track, and various setting data such as tone color and tempo data are written in this header. The performance data consists of one timing data and one
Or it consists of a combination of multiple event data (note data or setting data). The timing data is expressed as the number of clocks from the start of the song. Note data consists of note number and gate time data.

FIG. 4 is a diagram showing the structure of registration data. Five sets of registration data identified by numbers 1 to 5 are stored, and each data set has a similar configuration. Each registration data includes data such as tone, style, effect, tone, and tempo.

FIGS. 5 to 12 are flowcharts showing the operation of the automatic performance device.

FIG. 5 shows the main routine. When the power of this automatic performance device is turned on, an initialization operation is first performed at n1. The initialization operation is an operation of initializing various registers and hardware. Thereafter, performance playback processing (n2), key press processing (n3), panel switch processing (n4), performance recording processing (n5), event clearing processing (n6), and other processing (n7) are repeatedly executed.

The performance playback process (n2) is an operation of reading out already recorded automatic performance data and producing sound. The key pressing process (n3) is an operation for controlling the production/silence of musical tones based on the on/off status of the keyboard 107. The panel switch processing operation (n4) is an operation based on turning on various switches provided on the operation panel. Performance recording process (n
5) is an operation of reading performance data and writing it to a sequence track. Further, the event clear processing operation (n6) is an operation for clearing already recorded event data. Other processing operations (n7) include main volume adjustment operations and the like.

FIG. 6 is a flowchart showing the timer interrupt operation. In this operation, 1 is added to the tempo clock register TC (n11).

FIG. 7 is a flowchart showing the performance reproduction processing operation. This operation is a process of reading automatic performance data recorded on the sequence track and performing automatic performance data. Since this operation is an operation executed when the play switch 12 is turned on, the play switch 12
The play flag PLAY that is set by turning on is determined (n21). If PLAY is 1, the following operation is executed, and if PLAY is not 1, the process returns directly. At n22, the timing data pointed to by the pointer at that time is read out (n22), and it is determined whether it matches the contents of the tempo clock TC (n23). If the TC and timing data match, it is the timing to read the next data, so operations from n24 onwards are executed. T.C.
If the timing data and the timing data do not match, it is not the data read timing, and the process returns as is. n24
Then, the read address of the sequence track is incremented to read new data (n25). The type of data read out is determined in n26.

If the read data is note data, this note data is output to the sound source circuit (n28),
Return to n24 to read the next data. If the read data is setting data, the setting data is output to a necessary circuit such as a sound source (n29), and the process returns to n24. Furthermore, if the read data is timing data, the next event data will be read at this timing, so the process returns directly. Furthermore, if the read data is end data, the play flag PLA
Reset Y (n27) and return.

FIG. 8 is a flowchart showing key press processing. In this operation, sound generation/silence data is transmitted to the sound source based on whether the keyboard 107 is turned on or off. First, the key event buffer is scanned at n41. This key event buffer is stored in the key press detection circuit 106.
It is set in. Thereby, it is determined at n42 and n46 whether there is a key-on or key-off. If there is no key-on or key-off, the process returns directly. If there is a key-on, from n42 to n43 to n45
Proceed to the operation. First, in n43, a sound generation channel for generating a musical tone corresponding to a key-on is assigned. Let the assigned channel be the i-channel. In this case, if all channels of the tone generator circuit 111 are used, truncation processing is performed to forcibly mute the musical tone whose sound generation was started earliest. Next, the key-on flag KONi corresponding to this channel is set to 1, and the note number corresponding to the turned-on key is set in the key code register KCDi (n44). Next, a note-on signal and a key code are transmitted to the i-channel of the sound source circuit to start sound generation (n45).

If the key is turned off, the process proceeds from n46 to n47 to n51. First, the note number of the turned-off key is set in the off-key code register OFFKCD. Next, search for the channel that is producing the musical tone of this OFFKCD (n48), and if there is a corresponding channel, reset the key-on flag KONi of that channel (n50), and output a note-off signal to that channel. (n51). If there is no corresponding channel, the process returns as is based on the judgment in n49. That is, even when there is no key-off, the sound may be muted by truncation, decay, etc.

FIGS. 9 to 11 are flowcharts showing panel switch processing. This operation is an operation in which data is set in the register based on turning on the panel switch. First, the panel switch event buffer is scanned with n61. Through this scan, it is determined whether or not the play switch 12, the recording switch 13, the stop switch 11, the registration number switches 21 to 25, the registration data registration switch 26, and other switches are turned on.

When the play switch 12 is turned on, the operations from n63 to n67 are executed based on the judgment at n62. First, record flag REC and play flag PLAY on n63.
It is determined whether both are 0 or not. If it is not 0, there is no need to perform a new playback operation, so the operation exits from this operation. Recording flag REC, play flag P
If both LAYs are 0, n6 is used to execute the playback operation.
Proceed to step 4. At n64, the play flag PLAY is set to 1, and the tempo clock register TC is cleared. Next, the start address of the automatic performance data memory (sequence track) is specified (n65), the header is read out, and setting data such as tempo and rhythm type are output (n66). Next, the address of the sequence track is incremented and this operation is exited (n67).

When the recording switch 13 is turned on, n
Based on the judgment in step 68, the operations in steps n69 to n73 are executed. First n
In step 69, it is determined whether the recording flag REC and the play flag PLAY are both 0. If it is not 0, there is no need to perform a new recording operation, so the operation exits from this operation. Recording flag REC, play flag PL
If both AY are 0, n70 is used to execute the recording operation.
Proceed to. At n70, the recording flag REC is set to 1, and the tempo clock register TC is cleared. Next, specify the start address of the automatic performance data memory (sequence track) (n71), and write the setting data set at that time to this area (n72).
, increments the address and exits from this operation (n73).

When the stop switch 11 is turned on, the operations n82 to n87 are executed based on the determination at n81. First, it is determined whether the recording flag REC or the play flag PLAY is set (n82, n85). If the recording flag REC is set, end data is written at the end of the sequence track (n83), the recording flag REC is reset (n84), and this operation is exited. In addition, if the play flag PLAY is set, a note-off signal is output to all channels that are currently sounding (n86), and the play flag PL is set.
Reset AY (n87) and exit from this operation.

In steps n88 and n89, it is determined whether the registration number switches 21 to 25 and the registration data registration switch 26 are turned on at the same time. If these switches are turned on at the same time, the registration data specified by the registration number is registered. Therefore, the specified registration number is set in the REG register (n90), and each setting data set by turning on each switch at that time is written to the REG area of the registration data storage area (n91).
The preset registration flag PRE (REG) is reset (n92). The preset registration flag is a flag that is set when preset data is stored in the registration memory.

[0025] In n101, the registration number switch 21
.about.25 is turned on alone. If it is turned on alone, the registration number of the turned-on switch is set in REG (n102), and the data specified by REG is read from the registration data storage area (n103). Next, preset register flag PR
E (REG) is determined (n104), and if it is set, the name of the preset data is displayed (n10
5). Next, each of the plurality of setting data read as registration data is written into the event buffer as on-event data (n106), and this operation is completed. By writing each setting data of the registration data into the event buffer in this manner, each setting data is individually recorded on the sequence track in the performance recording process (see FIG. 12).

Furthermore, if any other switch is turned on (n107), setting data corresponding to that switch is output (n108).

FIG. 12 is a flowchart showing the performance recording processing operation. Since this operation is executed only when the recording flag REC is set, the recording flag REC is first determined (n111). If REC is set, execute the following operation, and if reset, return directly. At n112, the event buffer is scanned to determine whether or not there is event data (n113). If there is no event data, simply return. If there is event data, check the event data. This check is to check whether the event has the same setting data as that set at that time. That is, since the registration number data is broken down into each setting data, the same setting data may overlap. If the event is related to the same setting data, that event is skipped (n115). If the event does not have the same setting data, timing data indicating the timing of the event is written (n116), and the address is incremented (n117). Next, write the event data that occurred (n118) and increment the address (n
119). The same operation applies to all simultaneous event data stored in the event buffer (n121,
Repeat steps n122, n118, n119). Note that when the registration number data is broken down into a plurality of setting data, all the setting data are written to the event buffer as simultaneous events.

In the above operation, all of the setting data included in the registration data is written to the sequence track, but only a part of it may be written. Further, the recording operation to the sequence track is not limited to real-time recording, but may be step recording.

[0029]

[Effects of the Invention] As described above, according to the present invention, each setting data of the registration data specified by the registration number is recorded individually, so that the contents of the specified registration data are not changed afterwards. Even if the settings are changed, the original settings can be retained and automatic performance can be performed. Furthermore, it is also possible to play the song on an automatic performance device that does not have a registration function. Another advantage is that it is easy to change only part of the registration data after recording.
