TL;DR: use speeds that are a factor 11 for delay. (0,11,22,33…99) and you will likely get good results. https://www.instagram.com/tv/CLzXgFFFlGy/?igshid=srvavtzkwb93
Maybe this is useful/interesting to some people…I plotted out some of the delay speeds for the OP-1 and then figured out a formula to get a rhythmic delay speed based on your BPM.
Speed = BPM*11/24 - 11
so if your bpm is 120 you get
Speed = (120*11)/24 - 11
Speed = 1320/24 - 11
Speed = 55 -11
Speed = 44
or more simply (but rougher)
Speed = (0.46*BPM) - 11
If you try this out,
You should find, at the outermost circle, your delay will repeat every bar.
When you change the blue encoder every circle is a half, so as you tighten down the blue circle you will get 1/2, 1/4, 1/8, 1/16th 1/32 delays.
You can also get triplets by doing the calculation like this
Speed = (0.69*BPM) - 11
