I like this idea for Kria. One thought is that it might make sense to house that interface as an alternate for the Duration page as the two would not be used simultaneously per track? Or maybe just an alternate function on the Duration page per step? I’m thinking that pressing Duration page button and a step simultaneously converts the slider from top-down to bottom-up indicating ratcheting mode. The further up you go, the more ratchets per step? Or each vertical box represents an additional trigger so you could space them erratically for up to five additional triggers per step?
EDIT: if we went the first route and just created an Alt-Duration page for ratcheting, burst, and beat-repeat functions, then you could use the top “Time” bar as a probability slider per-step. Getting in the weeds a little here but I think this would be fantastic. That Alt page would be easy to differentiate from the others with its top-line bar and bottom-up sliders (different from Octave page).
