The sine, saw and square waveforms are produced by a set of specially designed optical discs that are mounted to each motor’s shaft. Each motor disc has three “tracks” engraved onto its reflective surface - designed as circular optical representations of the sine, saw and square waveforms.
Each reflective “track” is paired with a separate infra-red laser and sensor that picks up the reflected beam. As the disc rotates and brings the differently shaded areas in circular motion, the infra-red reflectivity sensor begins outputting a so-called “Optical Waveform” - technology that we developed specifically for the MOTOR Synth.
The "M" waveform is produced by a set of electromagnetic pickups that are placed next to each motor’s rotating inner coils. These create electromagnetic fluctuations that can be amplified to produce a unique motor waveform.
