So what YOU are saying, which is different than I'm getting from other
sources, is that MTC RECEIVE in ardour does NOT work, and MTC SEND

this is just always so about the offset.  i've always had my cakewalk set to
offset to :03 seconds when I sync to darwin. it's just because it takes a
second for the sequencer to catch the stream.

me too.  MMC and MTC are really two entirely different things, as far as I
understand it.  MMC is just stuff like "hey start!"  and "hey stop"  - MIDI
Machine Control - MTC is MIDI Time Code - which is an exact replica of SMPTE
time code and works exactly the same way.   now MTC of course sends
start/stop commands - so...maybe it USES MMC to do so...
