The SIM-RHYTHMICON plugin gives you the chance to explore and play a virtual version of this remarkable polyrhythmic instrument built by Leon Theremin in 1931. Each key from middle C up to Eb5 plays a progressively faster beat division, each with its own harmonically related pitch pulses.
I’ve also provided features not possible on the original one while hopefully being faithful to Henry Cowell’s vision when he commissioned its manufacture.
The user guide includes the notes I made while investigating the instrument. Click on the picture to download the zip which contains 32 and 64 bit plugins and a 32 bit one for XP users. If you want to see how it works get a copy of FlowStone and open the fsm schematic file.
