I’d love this as well. I think the interface is a little tricky to fit into Ansible (stretta is using the m4l device on the screen in this demo as well), but the basics should barely fit. Something like
turn encoder = change density
hold left button and turn encoder = reseed pattern for that encoder
hold right button and turn encoder = change speed for that encoder
Not sure about the specifics. Also, I think it would be nice to find some use for the CV outputs, even if its just the density or speed of that output expressed as a voltage. Or they could output a gate on every step that the pattern doesn’t generate a step on, such that you get both the pattern of gates you set up with the encoder as well as the inverse of that pattern. That’s usually very useful for logic operations.
