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
