Thanks, yes, I found OpenMPT and MilkyTracker is similar: part of the whole early computing thing: chiptunes, Amiga, strange hardware, weird effects, oddball UIs, etc. I’m impressed that people still want to do this stuff but that’s not me.
I just want to use MOD as a convenient publishing format for music I already have in MIDI so that Unity can play it, without going to the size of MP3 or OGG. Any suggestions?
