I got transport control, MTC syncing and fader, pan and mute working, last night! My issue was definitely with my MOTU MTP-AV. After I replaced it with an M-Audio MIDISport, everything started working. It was easier than I thought, but actually will be a tedious process to get fader control, mute and panning running (it was midnight when mapped channel 1 working, then went to bed since I have a day job). I will post instructions tonight or tomorrow, once I've had a chance to sit down and pull together the procedure. There aren't many steps to this which is great but if you're a noob to things like Audio clock vs. MTC vs. MIDI sync and how that relates to what you are trying to accomplish, I'd bet it has added to the problems that people have had while trying to set this up over the years. The good news is that you don't need a DLL file, just patience and a working MIDI interface, which will be essential.
