The GS Music Bree6 is a six-voice polyphonic analogue synthesizer designed for musicians seeking a powerful and intuitive instrument with a fully analogue signal path. Each of its six voices features a single voltage-controlled oscillator (VCO) and a sub-oscillator, processed through a mixer, a 4-pole low-pass ladder voltage-controlled filter (VCF), and a voltage-controlled amplifier (VCA). The digital control system includes a low-frequency oscillator (LFO) and two ADSR-type envelope generators, while an integrated stereo digital effects processor provides chorus and delay. With MIDI Polyphonic Expression (MPE) support, 512 preset slots, and extensive connectivity options including MIDI, USB, and balanced stereo outputs, the Bree6 is a versatile instrument for professional sound design and performance.

Intuitive Interface and Direct Control

The GS Music Bree6 features a user-friendly interface with a one-knob-per-function design, ensuring immediate access to every control parameter without menu diving. This layout allows quick and efficient sound shaping, making it ideal for both live performances and studio work. The synth offers MIDI In, Out, and Thru, USB connectivity, balanced stereo audio outputs, a headphone output, and CV inputs, ensuring seamless integration with modern setups.

Fully Analogue Signal Path

The Bree6 employs a completely analogue signal path, starting with a single VCO per voice alongside a sub-oscillator that generates a square wave one octave below the main oscillator. The oscillator section offers both sawtooth and pulse waveforms, with pulse width modulation (PWM) that can be modulated via the LFO. The oscillator’s tuning can also be adjusted, providing flexibility for tonal shaping.

Advanced Filtering Capabilities

The filter section includes a 24dB-per-octave 4-pole low-pass ladder filter with resonance control. The filter can be modulated by one of the ADSR envelope generators (EG1), with velocity sensitivity affecting modulation depth for dynamic response. Additional modulation options include control via the LFO, the modulation wheel, and aftertouch, allowing intricate shaping of harmonics and timbre.

Stereo Digital Effects Processor

A built-in stereo effects processor expands the sonic possibilities of the Bree6. The chorus effect employs multiple modulated delay lines to emulate the lush textures of string ensembles and vocal harmonics. The stereo delay effect offers a maximum delay time of one second, enriching the spatial depth of sounds and enhancing the overall mix.

Comprehensive Modulation Options

The Bree6 features a versatile LFO with selectable waveforms, including triangle, ramp up, ramp down, square, and random with sample and hold. The LFO operates within a frequency range of 0.1Hz to 100Hz, providing modulation for the VCO, VCF, and VCA. This allows for dynamic sound movement, from subtle vibrato to extreme pitch modulation.

Precision Envelope Generators

Two ADSR-type envelope generators provide detailed control over the dynamics of both the amplifier and the filter. These envelopes enable precise shaping of attack, decay, sustain, and release parameters, allowing the creation of expressive and evolving soundscapes.

MIDI Polyphonic Expression (MPE) Compatibility

The Bree6 supports MIDI Polyphonic Expression (MPE), offering enhanced performance articulation when used with compatible MPE controllers such as Osmose, Linnstrument, and Geoshred. This allows independent expressive control of each note, making it ideal for nuanced and organic performances.
