Gamechanger Audio Motor Synth

The world's first electro-mechanical desktop synthesizer

The Motor Synth is based on a unique motor oscillator engine - it is a system of eight electro-motors that are able to instantly and precisely change their rotation speed in order to produce musical notes.

These motor oscillators can produce four distinct waveforms - sine, saw, square and the so-called "M" waveform.

The "M" waveform is produced by a set of electromagnetic pickups that are placed next to each motor’s rotating inner coils. As the coils rotate the motor’s coils create electromagnetic fluctuations that can be amplified to produce a unique motor waveform.

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 misc has three “tracks” engraved onto its reflective surface. These “tracks” are designed as circular optical representation 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” - a proprietary technology that Gamechanger Audio developed specifically for the MOTOR Synth.

TWO INDEPENDENT MOTOR VOICES
The Motor Synth offers two separate motor voices with 4 electromotor oscillators each - both voices can operate in mono, unison or in four-note polyphonic mode.

Both motor voices are equipped with a separate set of controls for adjusting VOLUME, SCALE, WAVESHAPE, individual AMP ENVELOPE engines for each musical note, as well as very detailed control over a deep and versatile PORTAMENTO / PITCH MOD section (called “Acceleration / Brake” ).

SEPARATE MULTI-MODE ANALOG FILTERS
Both motor voices are equipped with a separate analogue multimode filter section with adjustable DRIVE, CUTOFF, RESONANCE, ENVELOPE SHAPE & AMOUNT and FILTER TYPE.

There are four analogue 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”.

DIGITAL VOICE
The MOTOR Synth MK II features an additional third voice - a digital engine that can be used either independently, or to augment the raw sound of the motor voices. The digital engine (DCO) can be used to produce various classic waveforms (with waveshaping), or as a noise generator.
The DCO is also equipped with a separate, fully controllable AMP ENVELOPE, PORTAMENTO section, and its own digital multimode Filter designed to reproduce the 4 analog filter modes.

CONFIGURABLE STEREO OUTPUT
The Motor Synth has a single output jack that can be configured either as mono, or as a stereo output - thus routing the synth's two motor voices into separate channels. The digital voice can also be routed to the V1 or V2 outputs, or to both.

CROSS-MODULATION AND DETUNE OPTIONS
The Motor Synth features a dedicated center indent potentiometer for creating amplitude cross-modulation with either Voice 1 or Voice 2. The Detune / Drift knob gives you two kinds of oscillator detune effects.

MODULATION SECTION WITH THREE ASSIGNABLE LFO'S
The Motor Synth MKII also features an extremely powerful modulation section that includes 3 individual LFOs with adjustable positive and negative depth controls. Each LFO can be easily assigned to almost any knob or encoder value on two independent modulation slots A and B.
There are five independent modulation waveforms available for each LFO - each with a detailed waveshaping engine.

ARP, MOTION RECORD, SEQUENCER
- Powerful arpeggiator engine offers detailed control over a large 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.

PERFORMANCE KEYBOARD
Non-velocity sensitive 8 key keyboard with 4 pitch shift encoders - this is a small but powerful note input system with a lot of performance tricks up its sleeve. Alternatively, the MOTOR Synth is fully MIDI and CV compatible and can be used with all of your favorite keyboards (incl. poly-aftertouch), controllers and sequencers.
