The time ports can translate from MTC to/from MIDI beats, but at a fixed tempo (125bpm). So, how would I generate MIDI clocks, at my specified tempo, from an MM application? Realtime clock packets out of a data port? And how should a MM application sync to another at the beat level rather than absolute time? One of the things I tried was the timebase demo application (HourGlass) with its timeport running to the serial driver, and the serial driver enabled for MIDI clock output. That gets me a solid 125bpm sync code. Not too useful. Performer seems to manage both input and output of MIDI clocks, so it's presumably possible, but I don't see anything in the documentation which explains how.
