The operator group 18 includes a setting operator 18a for the user to arbitrarily set the various setting information described above for each track of the performance data, and a performance for setting the setting information by operating the setting operator 18a. A numeric keypad 18b for designating time in the data and inputting various set values, a performance start instruction operator 18c for instructing start of automatic performance, and end of performance for instructing end of automatic performance An instruction operator 18d and another operator group 18e for instructing various processes such as selecting performance data to be automatically played are provided.
[0026]
Here, the setting information set by the user operating the setting operator 18a and the numeric keypad 18b is written in the flash ROM 24 in the setting process (S512) of the main process. FIG. 4 shows an example of the contents stored in the flash ROM 24. The setting information is reproduced in the performance data in association with the “music title” as identification data of the performance data for which the setting information has been set. “Reproduction time”, “content” indicating the type of setting information, and “value” indicating the setting value of the setting information are stored.
[0027]
Next, the main processing in this automatic performance device will be described with reference to the flowchart shown in FIG. This main process is started when the power is turned on, the power is cut off, or the automatic performance end operator 18d is operated, or all the performance data being automatically played is reproduced and the automatic performance process is terminated. It is executed repeatedly until you do.
[0028]
When the main process routine is started, first, various initialization processes such as clearing the buffers and registers of the RAM 16 are performed (S502).
[0029]
When the initialization process is completed, the performance data (automatic performance information) stored in the external storage medium 22 is stored in the performance data storage area of the RAM 16 (S504).
[0030]
Next, it is determined whether or not the setting information having the same song title as that of the performance data stored in the RAM 16 in S504 is stored in the flash ROM 24 (S506).
[0031]
If it is determined that the setting information is stored in the flash ROM 24, the setting information stored in the flash ROM 24 is stored in the RAM 16 (S508). At this time, the setting information stored in the RAM 16 from the flash ROM 24 is only the setting information having the same song name as that of the performance data stored in the RAM 16 in S504, and the song name and flash of the performance data stored in the RAM 16 in S504. The setting information stored in the ROM 16 is determined by comparing the setting information stored in the ROM 24 with the song name. Further, when the setting information in the flash ROM 24 and the setting information having the same music title, reproduction time, and contents exist in the RAM 16, the value stored in the RAM 16 is overwritten with the value stored in the flash ROM 24.
[0032]
When the process of S508 is completed, or when it is determined that the setting information is not stored in the flash ROM 24 in the process of S506, the process proceeds to S510.
[0033]
In the process of S510, it is determined whether or not a setting information setting instruction has been made by operating the setting operator 18a.
[0034]
If it is determined that a setting information setting instruction has been issued by operating the setting operator 18a, the setting information is stored in the RAM 16 and the flash ROM 24 based on the setting instruction (S512). Specifically, when the setting information is instructed by operating the setting operator 18a, the “song name”, “playback time”, “content”, and “value” specified by the numeric keypad 18b or other operator group 18e. Are set in the RAM 16 and the flash ROM 24.
[0035]
At this time, if this automatic performance device is performing automatically, for “Song Name” and “Play Time”, set the name of the currently playing song and the current performance time, respectively, and “Content” and “Value” "Is set as specified by the numeric keypad 18b or other operator group 18e.
[0036]
On the other hand, when the automatic performance device is not performing automatically, “playback time”, “content”, and “value” are set as specified by the numeric keypad 18b or other operator group 18e, and “song name” is set. For, set the name of the currently selected song. Here, when the power is turned on, the song stored at the head of the external storage medium 22 becomes the “currently selected song name”. The “currently selected song name” is appropriately set by the numeric keypad 18b or the other operator group 18e. Can be specified.
[0037]
When setting information is stored in S512, if setting information having the same content already exists at the same reproduction time, the setting information by the operation of the setting operator 18a is overwritten.
[0038]
When the above-described processing of S512 is completed, or when it is determined in S510 that the setting information setting instruction has not been given by the operation of the setting operator 18a, the processing proceeds to S514.
[0039]
In the process of S514, it is determined whether or not automatic performance is being performed. The automatic performance is started by operating the performance start instruction operator 18c.
[0040]
Here, when the automatic performance is not being performed, that is, when the end of the automatic performance is instructed by the operation of the performance end operation indicator designating operation element 18d, or when the reproduction of all the performance data is completed, the other processing of S518 is performed. move on.
[0041]
On the other hand, if it is determined in step S514 that automatic performance is being performed, automatic performance processing is performed for each tick based on performance data (setting information and performance information) that is automatic performance information stored in the RAM 16. (S516), and the process proceeds to other processing of S518.
[0042]
In the other processing of S518, “song title”, “playback time”, “content”, “value” are designated by detecting the operation of the numeric keypad 18b and other control group 18e, and various other settings are made. Perform the process. When the process of S518 ends, the process returns to S510.
