[sdiy] New MIDI (was free AS3320, AS3340, AS3310 and AS3360 samples)

[Tom Wiltshire]

TBH, I’d be happy enough with standard 5-pin DIN MIDI running at a higher rate. Bump it up to 500KBaud and I’m happy. More if you can.

Latency then becomes so low that I stop caring, and other questions start to be pertinent instead like “How long does the synth take to react?” rather than “how long does the message take to arrive?”
