"Ancestor of the Drum Machine: Leon Theremin's Rhythmicon
The Russian inventor Leon Theremin is best known for the eponymous instrument he created around 1919. But another invention of Theremin's is perhaps even more prophetic of later developments in electronic music: the Rhythmicon, produced in 1931 at the behest of the American composer Henry Cowell. This device allowed for the real-time generation of complex rhythmic patterns thought to be unperformable by humans. Each successive note on the keyboard triggered a division of the basic beat in whole number ratios: the second key beating twice for each basic beat, the third key beating three times, and so on.
This video shows the Russian scholar Andrey Smirnov demonstrating the how the Rhythmicon is played. The device shown in the video is likely the later version, developed in the 1960s and now housed in the Theremin Center in Moscow."

VINTAGE ANALOG Companion 4 in the floor THEREMIN percussion combo!

Dual-Action 60's Analog Drum Madness! Originlly put out by Companion a Japanese company this one's been modded to be a super rare, way-out & wild, analog drum machine with a photocell theremin bent in for good measure. It's played manually by hand or foot and it has some fat analog sounds that you'll hear on the demo below. The details are beautiful with chrome & rubber pedals, rainbow control panel and simulated wood veneer covering. Decay times for each drum are easily tweaked inside via the potentiometers, but are set nicely for optimal freak-out levels. There's also individual volume controls for each sound, a speed adjustment for the snare rolls & theremin, a switch to go from snare to theremin and a 1/4" output. Please note - this is the last one available to the public ever, the other 2 are owned by members of Depeche Mode and The Beastie Boys.
