I think maybe the modular version could suit me better even though the MB6582 would be really nice to have, although I think I want to finish a stereo config first as a part of expanding my synth collection, so i'm still deciding which i should do, but maybe the modular is better, although i really want to have some real time controllers. of course maybe expanding the MB later would be an option as well. Btw, a thought I had, would it be possible to build the control surface as an external part, not directly connected to the core and sid modules? Like a two piece MB Sid, maybe could make a secure wire that connects them and makes it controllable? just a thought, reflections? I'm considering later on to buy a Bitstream 3X, maybe I could use that to control the MB sid? Until I decide how to build my control surface.
