Exactly. The transport buttons do send outgouing MMC and reciprocally the
LEDs react to incoming MMC. So, if you make a closed-loop with ardour
you'll have total control over it. Even the jog wheel will do playhead
positioning...

Take note that almost every knob and slider of the US-224 (and also of its
bigger sister, US-428) do send MIDI controller messages. Taking ardour
again as an example, you are free to do arbitrary controller assignment,
at the application side that is

I guess thats what stands for a control surface, something that the US-122
hardly is at all. Phantom power is the only real decisive option on the
US-122. The US-224 really lacks that 48V supply--mostly because it does
already so much with stand-alone USB power :)

Cheers.
