My application is MIDI synced LFOs and delay time. I can only find a few threads about this from years past... http://groups.yahoo.com/group/csound--maths.ex.ac.uk/message/30577 http://csound.1045644.n5.nabble.com/midi-realtime-clock-td1120457.html http://comments.gmane.org/gmane.comp.audio.csound.tekno/155 The only specific idea among these threads is to read MIDI clock messages with the midiin opcode and use them to drive a phase counter. But as far as I can see from the manual and my tests, the clock message is still not a value reported by the midiin opcode. Does anyone have a solid approach for doing this? Cheers, Martin
