Turntable sequencer: geared patterns driven from the turntable

Three different patterns driven via gears from the main turntable. The main turntable plays beats via drum triggers and a peg record. The second platter turns at 1:2, playing chords via MIDI on a string synth (note how one of the arc segments slips towards the end of the clip, changing the pattern). The third platter runs at 2:3 playing a bassline with ball-bearings triggering a monosynth via CV.
This is a longer version of a section from my video of technical developments as part of my recently completed PhD, "Mechanical Techno: extended turntable as live assemblage."
