A unique electro-mechanical synthesizer with a raw, analog sound.

The Gamechanger Audio MOTOR Synth MKII is an analog, electro-mechanical synthesizer. It uses electromotors as its main sound source instead of conventional oscillators. The MOTOR Synth MKII has two ways of producing its unique core sound. It accelerates eight electromotors to precise RPM that correspond with specific musical notes. Each motor has a magnetic pickup placed next to it, and the resulting spinning coils generate a very industrial-sounding, exciting and raw analog tone. Think of it as eight harmonious revving engines pumping out a powerful intimidating noise.

Unique Motor Oscillating Engine

The MOTOR Synth MKII contains a system of electro-motors that are able to instantly and precisely change their rotation speed in order to produce musical notes. These motorized 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 disc 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 was developed specifically for the MOTOR Synth.

Two Independent Motor Voices

The MOTOR Synth MKII offers two separate motor voices with four electromotor oscillators each–both voices can operate in mono, unison or in four-note polyphonic mode and 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").

Independent Multi-Mode Analog Filters

Both motor voices are equipped with a separate analog multimode filter section with adjustable DRIVE, CUTOFF, RESONANCE, ENVELOPE SHAPE & AMOUNT and FILTER TYPE. There are four analog filter types–24 dB LP, 12 dB BP, 12 dB HP and 12 dB AP (All-Pass). These 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 (DCO)

The MOTOR Synth MK II features an additional third voice–a high quality 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 four analog filter modes.

Configurable Stereo Output

The MOTOR Synth MKII 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.

Modulation Section With Three Assignable LFOs

The MOTOR Synth MKII also features an extremely powerful modulation section that includes three 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.

Cross-Modulation And Detune Options

The MOTOR Synth MKII 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.

ARP, Motion Record, Sequencer

A 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 are assignable to all sound parameters. A built-in monophonic sequencer engine includes controls for micro-timing, probability, ratchets, pattern length, pattern saving and chaining and much more.

Performance Keyboard

Non-velocity sensitive eight key keyboard with four 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 MKII is fully MIDI and CV compatible and can be used with all of your favorite keyboards, controllers and sequencers.
