The Gamechanger Audio MOTOR Synth MKII, often referred to by enthusiasts as the Mk2 Motors, represents a significant leap in electromechanical synthesis. Building upon the groundbreaking foundation of its predecessor, the MKII refines and expands the sonic possibilities, offering a unique and powerful instrument for musicians seeking innovative sound design. This article delves into the core features and functionalities of the MK2 Motors, exploring what makes it a standout synthesizer in today’s market.
The Heart of the MK2 Motors: The Unique Motor Oscillator Engine
Central to the MK2 Motors’ distinct sound is its innovative Motor Oscillator engine. This system utilizes electro-motors capable of precise and instantaneous rotation speed adjustments, translating mechanical motion into musical notes. Four distinct waveforms are generated: Sine, Saw, Square, and the signature ‘M’ waveform. The ‘M’ waveform arises from electromagnetic pickups positioned near the rotating inner coils, capturing the fluctuations and amplifying them into a raw, textured sound. Sine, Saw, and Square waveforms are produced by optical discs mounted on each motor shaft, featuring engraved tracks that represent their respective wave shapes. Infrared lasers and sensors read these tracks, generating the “Optical Waveform,” a proprietary technology developed by Gamechanger Audio.
Dual Motor Voices and Independent Analog Filters
The MK2 Motors boasts two independent MOTOR Voices, each equipped with four Electromotor oscillators. These voices can operate in mono, unison, or four-note polyphonic modes, providing flexibility in sound creation. Each voice features dedicated controls for volume, scale, waveshape, individual amp envelopes, and a comprehensive portamento/pitch modulation section (“Acceleration/Brake”). Further shaping the sound, each Motor Voice includes a dedicated multi-mode analog filter with adjustable drive, cutoff, resonance, envelope shape and amount, and filter type. Four filter types are available: 24dB Low Pass, 12dB Band Pass, 12dB High Pass, and 12dB All-Pass. The MKII boasts improved analog filter circuits with increased headroom, faster envelope response, and a precise analog Keytrack mode.
Expanding Sonic Territories: The Digital Voice (DCO)
The MK2 Motors introduces a third voice: a high-quality digital oscillator (DCO). This versatile addition can function independently or in conjunction with the Motor Voices, broadening the sonic palette. The DCO offers classic waveforms with waveshaping capabilities and can also serve as a noise generator. Like the Motor Voices, the DCO has its own amp envelope, portamento section, and a digital multi-mode filter mirroring the four analog filter modes.
Modulation Powerhouse: LFOs, Cross-Modulation, and Detune
A robust modulation section lies at the heart of the MK2 Motors’ sound design capabilities. Three independent LFOs, each with adjustable positive and negative depth controls, offer extensive modulation possibilities. These LFOs can be assigned to nearly any knob or encoder value on two separate modulation slots (A and B), providing intricate control over various parameters. Five modulation waveforms with detailed waveshaping are available for each LFO. Beyond LFOs, the MK2 Motors features amplitude cross-modulation between Voice 1 and Voice 2 and a Detune/Drift knob for subtle or drastic oscillator detune effects.
Performance Features: Arpeggiator, Motion Record, and Sequencer
The MK2 Motors goes beyond traditional synthesis with integrated performance features. A powerful arpeggiator offers control over parameters like note accent, pattern shift, and note repeat. Multiple independent motion record lanes can be assigned to various sound parameters for dynamic sound evolution. A built-in monophonic sequencer provides in-depth control over micro-timing, probability, ratchets, pattern length, saving, and chaining.
MK2 Motors: A Synthesis Revolution
The Gamechanger Audio MOTOR Synth MKII, with its unique motor oscillator engine, extensive modulation options, and powerful performance features, redefines electromechanical synthesis. This instrument empowers musicians to explore uncharted sonic territories, crafting innovative and expressive sounds. Whether you are a seasoned synthesist or a curious sound designer, the MK2 Motors offers a unique and inspiring platform for sonic exploration.
