I have a 3u 104hp case, I really should try in that through the Christmas break.
I think I will scale down to 6u 126 case, and keep a few modules aside (Akemie’s Castle, Elements) because I can’t bring myself to fully part with them.
This thread has inspired me to design this as a downsized instrument:
The two Planar and the Walk would be to make the interaction with the system feel more immediate and “playable”, combined with grids (I should also get an arc, considering a Touche too). A central idea with this design, with Planars especially, is to be able to change as many parameters as possible within a patch with a single action, without any re-patching. There’s a hell of a lot of compromise in this design from what I have been building, the biggest being non modular external effects, and an all mono signal path and output. But I think this would be a very usable and fun system.
