Datasheet

3.4- Polyphonic Stand-Alone Mode 3 - Rewind Play(hold) / Pause: In

this mode a host controller is not required, SmartWAV 2 uses I0-I9 inputs

to trigger up to 10-channel polyphonic audio tracks, those tracks are

mounted on each channel at the power-on / initialization state of the

processor, the track names (xxx.wav files) are obtained from the

“tracks.txt” file(refer to section 3.9- The “Tracks.txt” File), be sure this file

exists in the root path of the inserted microSD card together with the

.wav files to be triggered.

The audio mixing is automatically handled by the system, but the way

each individual input triggers the mounted tracks in this mode is the

-In Rewind Play(hold) / Pause mode, if an input channel is triggered

during the channel is stopped or paused: the track mounted rewinds

and play while the trigger is hold, if during the playback the input

trigger is released: the channel will be paused. If no trigger is released

during playback: the channel will continue playing until the end of the

track and stop. In short, this mode works as a while-hold-play state.

Note: in the next diagram the yellow lines mean physical input

triggered and hold actions; purple lines mean automatic processor

actions.
