The sine, saw, and square waveforms are produced by a set of specially designed optical discs mounted on each motor’s shaft. Each motor misc has three “tracks” engraved on its reflective surface. These “tracks” are designed as circular optical representations of the sine, saw, and square waveforms

Each reflective “track” is paired with a separate infrared laser and sensor that detects the reflected beam. As the disc rotates and brings the differently shaded areas into circular motion, the infrared reflectivity sensor begins outputting a so-called “Optical Waveform” – a proprietary technology developed specifically for the MOTOR Synth.

There are four analog filter types – 24 dB LP, 12 dB BP, 12 dB HP, 12 dB AP (All-Pass). The new analog filter circuits have increased headroom, improved envelope response speed, and a very precise analog keytrack mode with adjustable depth, direction, and filter “glide.”

ARP, MOTION RECORD, SEQUENCER – The powerful arpeggiator engine offers detailed control over a wide variety of parameters, including note accent, pattern shift, note repeat, and more. – Multiple independent motion record lanes assignable to all sound parameters. – A built-in monophonic sequencer engine with controls for micro-timing, probability, ratchets, pattern length, pattern saving and chaining, and much more.

MKII is the result of years of painstaking development and improves many aspects of the original MOTOR Synth design, including:

– lower mechanical noise (due to custom motor engine, soft mounting, sound panels)
– added digital voice (DCO)
– 3 fully assignable LFOs
– upgraded filter and VCA section
– expanded controls for portamento, detune, and cross-mod
– powerful built-in sequencer, motion record, and arpeggiator engines
– unique Motor Vocoder mode
– Input “trigger” and “sidechain” modes
– Output split mode (motor voices on separate channels)
– improved user interface
and much more!
