Sending MMC (Play/Stop/etc) messages

[mungewell]

Nice little project, you certainly can't get cheaper than a Trinket! Is it possible to configure the Trinket to send Midi MMC messages for Play/Stop/Rec/Overdub?

I see some configuration here, but not sure what to change.

Also (as a bonus) is it possible/easy to make presses modal - for example a long press on 'Stop' would be a 'Stop + Rewind' (rather than 'Pause') and the next 'Play' be 'Play' (rather than 'Continue').

All of these would be super useful in controlling the Akai MPC's, and you might have a market if you intend selling these things.
