After being told by PGMusic support that Powertracks transport and mixer should respond to midi messages (e.g., start, stop, record, etc., as well as sliders, knobs and switches), I couldn't find the actual codes anywhere. As control surfaces need to be set to interact with codes specific to a piece of software, this results in a potentially endless guessing game. Are the codes listed anywhere? Has this been tried by anyone (I'm starting cheap with a USB-Midi Korg NanoKontrol, to see if it's possible).

Thanks for any help,
Bill
