I can see a nice use for sending MMC as well.
The octopus *doesn’t* send MTC currently, it sends MIDI clock, along with MIDI start and stop.
MTC is a time based protocol, while MIDI clock is tempo based.
With MMC you can control the transport on a sequencer or multitracker, which could still be acting as the MIDI clock master.
We would need to be able to designate whether the Octopus is MMC master or slave.
