Datasheet

3.3- Polyphonic Stand-Alone Mode 2 - Rewind Play / 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 / Pause mode, if an input channel is triggered during

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

play, if during the playback a trigger is present: the channel will be

paused. If no trigger is present during playback: the channel will

continue playing until the end of the track and stop. In short, this mode

works as a toggle-play state.

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

triggered actions; purple lines mean automatic processor actions.
