That sequencer is a cool idea!
I was thinking about it like basically the lowest position of the bar would be 0 and the highest would be 100% (kind of like how the top purple bar works…where the left-most is 0 and the right most is 100%). The device I was thinking of modulating it with was the ableton lfo which has scaling on it’s side:

I’ve gotten use to scaling and “lining up the parameters” in ableton, but that kind of range view where the scaling happens at the destination rather than the source is definitely easier to see. The overbridge knobs kinda do that in an interesting way.

Another thing that could be interesting would be a button that you hit to manually page to the next section which could be mappable. I have been having fun with Survey and @dr.katz Strokes today, and I was thinking it’d be cool to like step through the different stages with a euclidean pattern.
Alright done with pestering you with feature requests
what you’ve made is great fun!
