Reply to MIDI Clock LED without any soldering
MIDI Clock LED without any soldering Hey everyone! I finally got around to hacking on the Midi Fighter firmware. My first idea is to be able to get the MIDI Clock LED without soldering a new LED onto my Midi Fighter. The fourbanks_off mode, I'm using the top-left LED. In fourbanks_internal mode, I'm using the selected bank LED. In fourbanks_external mode, I'm not using anything. I'll probably publish my code to github or something similar in the near future, but in the mean time, here is a diff: WARNING: I take no responsibility for any damage my code does to your midi fighter, etc, etc Code:
