The Bree6 is a polyphonic analog synthesizer that features a fully analog sound
generation. It offers six voices of polyphony, each equipped with a single voltagecontrolled oscillator (VCO), and a sub oscillator.  The signal path includes a mixer, a 4-pole low-pass voltage-controlled ladder filter (VCF), and a voltage-controlled amplifier (VCA). The control signals are digitally generated, incorporating one low-frequency
oscillator (LFO) and two ADSR-type envelope generators. Additionally, the Bree6
integrates an effects processor with chorus and delay.

The Bree6 interface is engineered for straightforward and intuitive use, featuring one
knob per function and ensuring ease of access to its robust features, including MIDI
connections, USB, balanced stereo audio outputs, headphone output, and CV inputs.
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 features a single VCO plus a sub oscillator per voice. The oscillator includes
sawtooth and pulse waveforms, with pulse width modulation control that can be
modulated by the LFO. The oscillator tuning can be adjusted, and modulation can be
applied from the LFO. The sub oscillator generates a square wave one octave below the
main oscillator.

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 synthesizer offers a stereo ensemble type chorus effect. It simulates a string or
vocal ensemble using multiple delay lines modulated by their dedicated LFOs.
The stereo delay can reach a maximum delay time of up to 1 second.

LFO
The Bree6 contains one LFO with selectable waveforms (triangle, ramp up, ramp down,
square, and random with sample and hold). The LFO’s frequency can be set from 0.1Hz
to 100Hz, and modulation can be applied to the VCO, VCF, and VCA.
