More as a reaction to the increasing lameness of operating systems than
programmer-friendliness, I think the next major revision of OMS will
probably support some way to schedule MIDI output in advance. And choke it
off if you change your mind. (The MPU-401 returns!)

Sorry, I don't really do Windows much, but I understand that MME isn't that
horrible to program. I've played around a bit with Python and MIDI, and
even got something primitive working at one point, but I must have archived
the source because it doesn't seem to be on my hard disk ...
I wish I could volunteer to do this, but between work and trying to stay
sane by playing music, I really don't have the time. If someone else would
find the project a bit less daunting by my offering to help, I'm available
to answer questions ...
