Klevgränd has released Spinn, a four-band rotating modulation effect which they say is similar to a Leslie speaker, but doesn't aim to replicate it. It features four rotors (one per frequency band) with individual speed controls, acceleration and deceleration times, adjustable size and modulation. Each band also has a velocity control, which will adjust the speed according to the band's input level. Spinn also features custom amp modeling (clean or hot) and room simulation.
