I've not been following the form closely of late... but I recall seeing something where the host wasn't packaging MIDI efficiently and a fix is in the works??? (looking to see if I've imagined this...) rummage...

It works, sounds ok and doesn't seem to damage anything but you should never ever use the phone jack as a line out because... er, it's wrong? ;)

Yeah... a search suggests I have it wrong on fast write.... good luck.

I was hoping someone qualified would reply. I think you should not use digitalWriteFast as I believe it's meant for compatibility only in Teensyduino. I think you need not worry too much about the serial exchange...
