Dynacord CLS 222
The Moog Minitaur Soprano
This rotary speaker effect, vulgo Leslie®, was built by the german company Dynacord from 1989 till 2003. It was built in a white and a black version. Its predecessor was the CLS 22 form 1982. The newer got a third stereo wide setting on the the front panel and an additional Mono Out socket on the back. And some capacitors at the outputs were dropped on the newer revision.
Due to the splitting of the ingoing signal in bass and treble, sending each of these into two BBD lines (so 4 BBDs in total), and these the volume and the panning being modulated by one LFO for the bass and another for the treble gets the sound very close to the real thing. Of cause there is a ramping up and down when switching the speeds.
Both versions don't add distortion often heard when using rotary speakers, so you might need to add this using a different FX.
