Mode Operation Instructions

1.  I/O combination Mode 0(Key combination playback

The single-chip microcomputer controls the I/O combination to trigger (effective at low level), release after the specified track is played (IO0-IO7 returns to high level), and stop after the current track is played. If triggered again in the middle of the playback, a new track will be played and the playback will stop when it ends. If it keeps triggering (without releasing the level), it will play in a loop. The playback process is busy and effective.

Note: The title of the piece must be named according to a five-digit number.

2. IO Combination Mode 1(Level Combination Playback)

The single-chip microcomputer controls the IO combination to trigger the specified track (effective at low level), and continuously plays the specified track in a loop. The playback stops when the level is released (1O0-1O7 returns to high level). Release the level in the middle of playback to stop playing immediately. The playback process is busy and effective.

Note: The title of the piece must be named according to a five-digit number.

3. IO Independent Mode 0(Key independent Control)

1O0-1O7 independently controls 8 tracks. 1Otriggers (valid at low level) the designated track and then releases (1O0-1O7 returns to high level). Stops when the current track is played. If triggered again in the middle of the playback, a new track will be played and the playback will stop when it ends. If it keeps triggering (without releasing the level), it will play in a loop. The playback process is busy and effective.

Note: The title of the piece must be named according to a five-digit number.

4. IO Independent Mode 1(Level Independent Control)

IO0-1O7 independently controls 8 tracks. When IOtriggers (low level is effective) the specified track, it continuously loops and plays the specified track. When the level is released (IO0-1O7 returns to high level), the playback stops. Release the level in the middle of playback to stop playing immediately. The playback process is busy and effective.
