Playback Problems (Missing Notes)

Postby Majumafoo » Mon Feb 19, 2018 11:02 pm

Hey team,

I have noticed several repeating issues from songs I've created for my coil.

When I play them from my computer, through the interrupter to the coil, everything works fine.
However, when running off the SD card, certain notes are consistently missed.

Has anyone else experienced this problem?
Has anyone found a fix?

I've heard of this issue before, but I sadly lack the data to properly debug it. If you can figure out when it happens I can try to roll out a firmware fix.

Bayley,

Are you able to connect me with any resources so that I might help me dive into the issue?
I don't know anyone about OMD, and I haven't had much luck online.

OMD is a custom format, its just sequences of bytes indicating which notes to turn on and off. The exact formatting should be easy to discern from the interrupter source code.

If you could please have a peek at the converter code, I'd really appreciate some improvements.
If you need some source material to review, please follow this link. Nearly every OMD does not playback properly.

I consider the following to be particularly easy to hear issues with:
  • Cantina
  • Final Countdown
  • Green Hill Zone
  • I Want it That Way
  • Victory!
