This is so effing fantastic. I honestly can't thank you enough for this.
I've spent the past few hours going over what you've done and it is a perfect system for what I was after.
I'm on the fence on a few things (keeping the MUM M8 and Bifold - I haven't really clicked with them and not sure I'd want to keep them long term), but this is extremely helpful in helping me have a cohesive unit with great flow. I may rearrange that row a bit and see how else other modules might fit in.
I'm also going to create a pared-down version with just a single 6U and see where that takes me. Maybe half the 2 voice rows, some drums, modulation, and then finally control. I'm also toying with just getting 2 more 3U rackbrutes and replacing the 62hp palette and 64hp skiff. Then I can use the palette for random modules when I want to be out and about.
I also opted in for a unicorn account. I didn't want to lose all of the work you did!
