Hi all,
Would it be possible to use the WAV Trigger to switch between simultaneously-playing wav channels? For example, four tracks are concurrently playing, and separate input triggers select which track is routed to the audio out. Essentially, I need to keep the timing synched between multiple tracks but only output one at a time.
I’ve used the WAV Trigger for previous projects that were straightforward keyboard style trigger-play, but can’t sort out what the trigger function settings would need to be for this approach.
Thanks!
While you can’t accomplish this with the trigger functions directly, you can do it with an Arduino (such as a Teensy) and the WAV Trigger Serial Control Arduino library. The idea is to load and start all 4 tracks in sync and use the trackGain() command to mute them all. You can program the trigger inputs, now connected to the Arduino, to unmute one of the tracks using the trackFade() command (while simultaneously muting one that was already unmuted.) The tracks will stay in sync regardless of which one is unmuted.
If the tracks are all the same length (in samples) you can loop them all and they will remain in sync as long as they are left looping.
Hope this helps.

Great, thank you! And thanks for the great products!
So the inputs would be read through the Arduino’s GPIOs, and the play/mute/unmute controls are all serial commands that can be issued inside If controls for each input pin?

Yep! And then you’d then pass those on to triggers
