Level retrigger. When I/O port is low level, keep playing , high level will stop. it will re-play until high level.
8.1.4 Level trigger
Level trigger. When I/O port is low level, keep playing , high level will stop. After first play is over it won’t replay
even keep low level. Unless pull high then pull low and keep low level, it will be the second play .
8.1.5. On/off
A negative pulse start to play, next negative pulse to stop.
8.1.6. Down (Next)
Next(down) .A negative trigger play a group, next negative trigger play next group, untill last group, then no
more voice can be triggered.
