I'm having the same problem as the original poster, and the posted solution isn't working. I feel like I'm missing some simple yet crucial step or steps. And FWIW, midi is not my strong point.
Here's where I'm at -
1) Downloaded and installed the latest BL Cakewalk.
2) Plug in US2400 and place it into "Sonar" mode.
3) Enable the midi devices in Cakewalk - there are 6 total US2400 related devices ports (US2400, US2400(2), (3) etc), even though the US2400 manual indicates that there should only be 4.
4) Add the control surfaces - MackieControl, then MCXT(1), MCXT(2), etc - How many XT are required? 1 for every additional bank of 8 sliders (2), again, per the manual, or 1 for every additional midi device port (5)? Also, what is the correct In and Out for every MackieControl device? Ex. Device 1: US2400, Midi In:US2400, Midi Out: US2400; Device 2: US2400(2), In: US2400(2), Out: US2400(2) etc. - This is where I think I'm going sideways
5) Per the proposed solution above ("On the MackieControl dialog (the main one), click the "Configure Layout" button etc") - my rotaries do not click, nor do they show any red dots that might help gauge a visual "click" in this mode, or any mode unless I press the "Channel" button on the Tascam. Does the US2400 need to be in a special mode to accomplish this step?
6) Unless I'm again missing some step, page 18 of the US2400 manual isn't helping me.
Is there anything above that jumps out? Any help here is appreciated. I'll suffer the slings and arrows, I just really want his thing to work. What would be nice is if some user could create a script...
Thanks all.
