FORTH is a lot of fun for music programming. Build a phrase, make
copies of it, transpose it, hear it immediately. I've written
some code for PC/FORTH on the IBM PC, with a Roland MPU-401 MIDI
interface, which allows you to record, modify, generate, and play
back sequences. Anyone who sends me a valid network address can
get the source.
Especially welcome would be anyone who could come up with a version
of the code that would run under a public domain FORTH 83, so that
more people could use it.
