Programmable Options

The API840N provides different control functions for user

specified applications. They include:

* Non-sequential or Sequential Play-all

* Unholdable or Holdable trigger

* STOP or BUSY signal selection

* Automatic ramp-up/ramp-down or no ramp-up/ramp-down

Silence Compression

If a particular sound sequence includes periods of silence,

the API840N will automatically compress the silence to

save memory space. This compression will not affect

playback of the sound sequence.
