Thanks for the answer stefvanriet.
Much appreciated.

You are absolutely right, I view case setups as groovebox-type instruments I learn to play and improvise on for a while (before changing it all again) rather than canvas I patch/unpatch often. i just love the immediacy, playability and sound of eurorack (vs. dawless desktop grooveboxes).

As for hp constraint, I just need the focus. If I have too many options I tend to play less.

Anyhoo. Interesting notes. I like your "no 2 of the same module" take. It's true it could help me find new sounds and variations (even with a fixed patch :) ).

Also I will deduplicate stuff to add modulation.

And I really love the idea of a dj fader. I think it would be great to have another small case with a completely different take/sound and be able to switch from one "track" to the other. It would allow me to prepare a sequence while the other is playing, turntable-style.

I'll think about it and will circle back.
