Here's my idea for an OSC-based replacement for MIDI. (Actually, only the part that concerns sound generation. The sequencer stuff will go under a separate /SEQ namespace, and be described in a separate document). This is loosely based upon the SYN namespace by Fabian Ehrentraud. http://home.roadrunner.com/~jgglatt/OSC_Synth/osc_synth.htm
