Appunti MIDI

Coo blimey, the first bit of fun is going to be reading the .mid file, you can find hints and tips here:

All the things we're doing is essentially just passing MIDI around from one place to another, be it a serial port or a socket to another socket or serial port.

MIDI itself is a pretty straight forward thing to decode, just watch for a thing called "running status" (good article here) and also the two types of "note off" (a note on with zero velocity and a proper MIDI note off command).

That said, if you’re only triggering percussion and not "holding" a solenoid then you needn’t worry about note off messages either :)

I wish I could offer more help as it sounds like a fun project, but right now I’m up to my ears in development of our product, which we’re launching in a few weeks.

Let me know how you get on
