Hi Mark, have the (old) Tascam DM24 mixing console which has a Mackie HUI emulation. When I try to use it with this Mackie Control Surface for Cakewalk by Bandlab, my console displays some MIDI Framing error, and freezes, I have to switch it off and on to do anything. Most of the time Cakewalk freezes at this point as well. Do you have any idea what the problem could be ? I have tried the same with Cubase, and there the HUI emulation works just fine with my DM24.
