SMARTWAV 2

Datasheet

3.6- Polyphonic Stand-Alone Mode 5 - 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 Play / Pause mode, if an input channel is triggered during the

channel is stopped or paused: the track mounted plays, if during the

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

is present again: channel will continue playing from the current

paused position and so on. 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.
