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 voltage-controlled 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.

No Menu Diving 

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. 

Envelope Generators 

There are two ADSR-type envelope generators in the Bree6, designed for precise control over the dynamics of both the filter and the amplifier.  

MIDI Polyphonic Expression 

The synthesizer supports MIDI Polyphonic Expression (MPE), facilitating detailed performance dynamics when used with compatible MPE controllers. The Bree6 has been carefully tested with Osmose, Linnstrument and Geoshred.
