I’m probably in the minority, but at least for live performance, I’d like to experiment with option 1 if we can come up with a way to make it available. Option 3 is also workable, but the way I’ve been playing, gates would be nice to maintain.
this comes down to whether the voice selection buttons act as toggles or radio buttons - i was thinking the latter as it would make switching faster. could perhaps allow multiple buttons to be selected while held?
That sounds good. When one is held, pressing another would allow multiple selection, but pressing one remains radio button.
I’m not enamored with any particular multi-sequence implementation. Multiple mono sequences would certainly be lovely, as many have been saying. However it has to work is fine by me. Just looking forward to being able to layer.

1-Quantized, lit keyboard layout (as mentioned previously (I know my guitar fretboard, but it would be nice not to think about where I am on the grid constantly).
I’d also love to see the keyboard guide. I’ve gotten pretty good at finding my way spacially from practicing scales, but more visual reference points would be lovely.
