I sat down last night, reistalled RTPMidi, bought DAW Remote HD (
http://dawremote.com) and did manage to get it working with X3e under mackie control. I've got to admit, it's pretty sweet. Just having basic mix controls, mute, record arm, and solo (along with the transport) is very handy. Now I need to find the manual and figure out how to do punch points, markers, and the other goodies. It has buttons for EQ, dynamics, and some others, but I'm not sure how/what to map them to.
