Thank You Joe
That formula seems to work. When I use a Quick Knob the playback starts at 100 and I can go faster or slower accordingly.
Interestingly , if I used the HotKnob P to control playback speed It will work, but playback starts at 88 and then goes faster or slower.
My original intention was to keep the playback speed on the larger HotKnob and use the three Quick Knobs for 1-Play Start 2-Play Length and 3 – Filter.
This allows for a lot of versatility when manipulating loops during live performance by hand.
So having the same precision and clearer center point on the Hot Knob would be a nice feature if possible.
At least now I see the proper way to start playback at a “Zero” point
