Notice:
"Key combination playback" refers to the restoration of the original high level after io0-io7 output the corresponding level, similar to the key trigger once.
"Level combination playback" refers to the io0-io7 output of the corresponding level to maintain the same level.
The difference between "I/O combination (independent) mode 0" and "I/O combination (independent) mode 1" is that the former mode continues to play the current track until the end after releasing the level, while the latter mode immediately stops playing the track after releasing the level.
