I've been playing with the midiwrapper class I sent in yesterday and I'm convinced that it's getting to the useful stage. At least I was able to get ChucK noodling away on several modules while I worked :) With great embarassment I also finally noticed that string comparisons are already there so I can implement this: MIDIsender m; m.open("JD990"); Only works on Mac OS X for the moment, becuase we've got AudioMIDI setup to keep track of where things are plugged in. The interface is there for other platforms if you can identify ports somehow. The latest code for the class, fledgling documentation on how to use it and several examples showing useful functionality are at: http://www.rattus.net/~packrat/audio/ChucK/ I have several other things I want to do, but some of them are waiting on better string handling. A written note (C#3) to midinote converter is pretty high on that list. It might be easier to put into the std library, or should there be a MIDI library?
