Hi. I have an MP3 Trigger and a WAV trigger and they have been great on a variety of projects. Now I ran into something that seems simple but I can't get it to work on either board:
1) On power-up, several tracks should play sequentially. When the last track is done the first track plays. And so on...
On the MP3 Trigger, this is accomplished by shunting all relevant triggers to ground. No ini file needed.
2) A trigger input is dedicated to a "next" button so you can skip to the next in the sequence.
This scenario is described in the MP3 Trigger documentation:
The WAV Trigger has more logical options for each trigger, so I tried that too. But unless I'm mistaken, the WAV Trigger doesn't play tracks sequentially if you shunt several triggers. Instead it plays them simultaneously (if polyphony is on) or it quickly jumps to the last track (if polyphony is off).
I'm working on setting up Arduino serial control next, but I just wanted a reality check since I always thought these boards could do this "out of the box". Thanks, -Zach

As an example, I use the following single-line init file to make triggerThat does indeed work, BUT... after playing the "next" track, playback restarts from the first file, ignoring any later files.
18 be a "Next" function, then hard-wire the trigger so that my MP3 Trigger
powers up and loops continuously through all the tracks on the card.
