Would a negative offset CV slow down the rotation - is it summed with the control then clipped, or clipped then summed? edit- just realised it’s a bipolar control, so maybe CV attenuation is the answer…
This is insightful:
I’ve achieved this with audio Eurorack, for rotation of vector images:
cos(α+β)=cosα cosβ−sinα sinβ
sin(α+β)=sinα cosβ+cosα sinβ
And from reading about the navigator, a few of the Befaco A*B+C could be used for multipliers and sums to achieve Anchor and Position controls, along with a Through-Zero Quadrature LFO to provide rotation control. It’s the speed of that LFO that dictates speed of rotation… though I’m curious how the Navigator can be set to spin 8x only -
