This happened just the other day. When working in song mode occasionally my encoders get a bit wonky leading to large jumps (this especially happens in the of ln or pattern rep). Anyway, check out row009, this time I got a length of -1! It plays just one step. I’m pretty stoked as the minimum length is supposed to be 2 steps.
I wasn’t able to recreate it, but I have that row saved in a blank song if I ever want a 1 beat repeat.
Has anyone else ever seen this? Or have you stumbled upon any other useful glitches?
