I recently installed a Sparkfun MP3 Trigger board on my Williams Blackout to add background music. It works great with one exception, which I can't quite figure out. I've got it set to play songs randomly after the ball is launched. I've got 45 songs on the card but it seems to keep selecting the same five or six songs randomly. I've double checked my .ini file and everything seems to be set up correct.
I've also got a separate trigger set up to play one track for the outball. That works fine but occasionally the other trigger will pull that track to play during game play.
I've seen posts on creating a mod like this from a few years back and I wondered if anyone had suggestions on correcting this issue.

Yes, I took that into consideration. I'm wondering if I'm naming the files correctly. I'm only using two triggers on the board and I'm naming the files "001_filename" for the first switch then "002_filename1, 002_filename2, 002_filename3...etc" for the rest, with 'filename' being the name of the track.

Hmm. Not much there, starting letters and length are pretty random. I'm not really seeing any pattern with tracks played and ones not playing

One thing I recently discovered is the system appears to read the third digit of file names. I had files names 003, 013 and 023 and they were all playing on the #3 trigger.
