The GS Music Bree6 is a six-voice polyphonic analogue synthesizer designed for musicians and sound designers who require a versatile, fully analogue signal path. Each of its six voices features a single voltage-controlled oscillator (VCO) alongside a sub-oscillator, processed through a mixer, a 4-pole low-pass ladder voltage-controlled filter (VCF), and a voltage-controlled amplifier (VCA). A digitally controlled modulation section provides a low-frequency oscillator (LFO) and two ADSR envelope generators, while an integrated stereo digital effects processor delivers high-quality chorus and delay effects. Supporting MIDI Polyphonic Expression (MPE), 512 preset slots, and extensive connectivity, including MIDI, USB, and balanced stereo outputs, the Bree6 is a powerful tool for professional audio production and live performances.

Intuitive Design with Hands-On Control

The GS Music Bree6 is built for immediate, hands-on control, featuring a one-knob-per-function interface that eliminates menu diving. This direct-access approach ensures smooth workflow efficiency for both live and studio applications. Its connectivity includes MIDI In, Out, and Thru, USB integration, balanced stereo audio outputs, a headphone output, and CV inputs, ensuring compatibility with modern digital and analogue setups.

True Analogue Signal Path

With a fully analogue signal path, the Bree6 offers a single VCO per voice, complemented by a sub-oscillator that generates a square wave one octave below the primary oscillator. The oscillator section provides sawtooth and pulse waveforms, with pulse width modulation (PWM) controllable via the LFO. The oscillator’s pitch can be manually adjusted or modulated for expanded tonal flexibility.

Advanced Filtering System

The filter section features a 24dB-per-octave 4-pole low-pass ladder filter with resonance control. Modulation sources include an ADSR envelope generator (EG1) with velocity-sensitive modulation depth, the LFO, the modulation wheel, and aftertouch, offering extensive sound-shaping possibilities.

Stereo Digital Effects Processing

The built-in stereo digital effects processor enhances the Bree6’s sonic capabilities. The chorus effect creates lush, ensemble-like textures using modulated delay lines, while the stereo delay provides up to one second of delay time, adding depth and movement to any sound.

Comprehensive Modulation Capabilities

The Bree6 includes a flexible LFO with five selectable waveforms: triangle, ramp up, ramp down, square, and random sample-and-hold. Operating within a frequency range of 0.1Hz to 100Hz, the LFO can modulate the VCO, VCF, and VCA, enabling a broad spectrum of sound design options from subtle vibrato to aggressive modulation effects.

Precision-Controlled Envelope Generators

Two ADSR envelope generators provide detailed control over the filter and amplifier dynamics. These envelopes allow precise sculpting of attack, decay, sustain, and release times, making it easy to craft expressive and evolving sound textures.

MIDI Polyphonic Expression (MPE) Support

With full MPE support, the Bree6 enables nuanced and expressive performances when used with compatible MPE controllers such as Osmose, Linnstrument, and Geoshred. Each note can be independently modulated, allowing intricate real-time control over sound dynamics and articulation.
