Introduction
The Bree6 Keyboard is built to deliver an intuitive and expressive analog experience, combining a robust architecture with a carefully crafted user interface that invites exploration and creativity. Built upon a six-voice analog architecture, the Bree6 Keyboard delivers a powerful and expressive sound engine, capable of producing a wide range of textures, from solid basses and articulate leads to rich, evolving pads. Its carefully designed signal path, combined with an intuitive interface and a high-quality keyboard with velocity and aftertouch sensitivity, provides a direct and immersive playing experience.
Expanding beyond the desktop version, the Bree6 Keyboard incorporates an advanced arpeggiator and a built-in sequencer, significantly enhancing its creative capabilities. The arpeggiator features multiple layers of operation, allowing for complex rhythmic patterns and evolving sequences, while the sequencer enables users to capture and develop musical ideas directly from the instrument, making the Bree6 Keyboard a complete performance and composition tool.
Every aspect of the instrument has been developed with careful attention to detail, combining a refined aesthetic with a robust and purposeful construction. The Bree6 Keyboard features an all-metal build complemented by natural cedar wood side panels, and is hand-assembled to ensure quality and consistency in every unit.
It incorporates a semi-weighted keybed with velocity and aftertouch sensitivity, along with pitch bend and modulation wheels engineered in-house to provide precise, reliable, and expressive control.
Immediate Control. No Menu Diving.
The Bree6 Keyboard version is designed to deliver an immediate and intuitive hands-on experience, eliminating the need for deep menu navigation. Its interface follows a one-knob-per-function philosophy, providing direct access to all key parameters for fast and precise sound shaping.
Expressive control is at the core of the instrument. Velocity can be assigned to modulate both the filter and amplifier response, allowing dynamic tonal variation based on playing intensity. The modulation wheel provides real-time control over LFO modulation depth, targeting the oscillator pitch and/or the filter cutoff for expressive performance.
The instrument features a semi-weighted keybed with velocity and aftertouch sensitivity, ensuring a responsive and musical playing experience. It also includes dedicated inputs for sustain and expression pedals, with the expression pedal offering configurable assignment and adjustable response range for flexible control.
In addition to its performance capabilities, the Bree6 Keyboard integrates essential connectivity options, including MIDI, USB, balanced stereo outputs, headphone output, and external control inputs, making it equally suited for both studio production and live environments.
Signal Path
The signal path in the Bree6 is entirely analog, including a single VCO per voice, a sub oscillator, a mixer, a 4-pole low-pass ladder VCF, and a VCA. The control voltages are digitally generated, comprising one LFO and two ADSR-type envelope generators. It also features a stereo digital effects processor with Delay and Chorus.
Oscillator
The Bree6 Keyboard version features a single analog VCO per voice, complemented by a dedicated sub oscillator to enhance low-frequency content.
The oscillator provides two primary waveforms: sawtooth and pulse. The pulse waveform supports Pulse Width Modulation (PWM), which can be dynamically adjusted and modulated via the LFO to create evolving textures.
Pitch can be finely adjusted, and modulation sources can be applied to introduce vibrato and other expressive variations.
The sub oscillator generates a square wave one octave below the main oscillator, adding weight, depth, and richness to the overall sound.
Filter
The Bree6’s filter is a 4-pole ladder-type low-pass filter with resonance control. It can be modulated by EG1, with velocity affecting the modulation depth, and can also be modulated by the LFO. It can also be controlled by the modulation wheel and aftertouch.
Chorus and Delay
The Bree6 Keyboard version is equipped with a 4-pole ladder-type low-pass filter, designed to deliver smooth and musical frequency shaping.
The filter includes resonance control and supports multiple modulation sources, including Envelope Generator 1 (EG1) with velocity sensitivity, LFO modulation, and performance controls such as modulation wheel and aftertouch.
This flexible modulation system enables a wide range of tonal possibilities, from subtle shaping to more aggressive and resonant filtering.
LFO
The Bree6 Keyboard version includes a versatile Low-Frequency Oscillator that acts as a central modulation source.
Selectable waveforms include triangle, ramp up, ramp down, square, and random (sample & hold). The LFO frequency ranges from 0.1 Hz to 100 Hz, enabling both slow evolving modulations and fast modulation effects.
It can be routed to multiple destinations, including oscillator pitch and PWM, filter cutoff, and amplifier level.
Envelope Generators
The Bree6 Keyboard version features two ADSR envelope generators, providing precise control over both tonal and amplitude dynamics.
EG1 is assigned to filter modulation, while EG2 controls the amplifier. Each envelope includes attack, decay, sustain, and release stages, allowing detailed shaping of the sound over time.
Polyphonic Expression
The Bree6 Keyboard version supports MIDI Polyphonic Expression (MPE), enabling advanced per-note control when used with compatible controllers.
This allows independent manipulation of parameters such as pitch, pressure, and timbre for each note, significantly expanding expressive capabilities and performance depth.
