Spinn – 4-band spin modulation effect. It bears a resemblance to Leslie’s speaker, but does not intend to reproduce it (call it optional if you like).
Four rotors (one per band) with individual controls for speed, acceleration and deceleration times, variable size and modulation.
Each lane also has a velocity controller that will adjust the speed according to the input level of the lane. Spinn also offers custom amp modeling.
