I'm not clear as to what you've accomplished. I thought the intention was to try using both consoles in remote layer without cascading. Sounds like you only configured the dm4800 for remote layer use but I'm confused as to why you assigned 4 Maxkie controllers rather than the required 3 (1-8, 9-16, 17-24)? Using the remote layer in cascade mode, if I had a 40 track project, tracks 1-32 would spread across both consoles. If I nudged or banked it would increment tracks on console 2. I was under the impression that you were looking for this kind of functionality without being able to cascade 2 different DM models. If this were at all possible, again, you'd have to have USB connections from both consoles to your Mac.
