Thanks for pointing out the midicsv tools. I'm sure they will come in very handy. And now the good news. Timidity does indeed support the single note change. In fact it's even in the docs (README.mts) (oops!). I've attached a MIDI file that plays an A4 followed by a C4 but the A4 is tuned to a C4 so you should hear two middle-C's. (Note, in my MIDI file there is a spurious sysex command that is an artefact of my program but does not affect the playing of the file.) Running cvsmidi shows how to construct the proper sysex command. This is really great news and means that basically we can just send specific frequencies to MIDI and not mess with tuning tables or anything else. The next step is trying to understand how MIDI encodes its frequencies (it looks confusing to me but I'm sure I'll figure it out eventually). Dave On Mon, May 18, 2015 at 2:41 PM, A.
