Superbooth 2026: GS-Music has announced the Bree6 Four Octaves Edition of its analog polyphonic Synthesizer.
Shortly before Superbooth 2026, Argentine developer Guido Salaya of GS-Music released the bree6 in the keyboard version.
However, since there was sufficient demand for a larger keyboard, GS-Music has now announced the bree-6 Four Octaves Edition.
GS-Music bree6
The bree6 Four Octaves Edition differs from the regular keyboard only in its larger keyboard. It now features four octaves instead of three, has the same high-quality sound, and supports velocity and aftertouch.
Otherwise, the GS-Music bree6 Four Octave Edition is the same lovely vintage-style analog polyphonic Synthesizer. The interface has the same rich amount of knobs and buttons, making it very hands-on experience.
It’s a 6-voice analog polyphonic Synthesizer with a single analog VCO per voice, a 24dB/oct lowpass ladder filter with resonance, two ADSR envelopes, and a single multi-wave LFO.
Also onboard is the same 32-bit multi-FX processor with delay and chorus, which adds a nice layer of goodness. Further, you have a creative arpeggiator with multiple layers of operation, allowing for complex rhythmic patterns and evolving sequences.
A sequencer is also onboard that enables users to capture and develop musical ideas. Like the desktop and standard keyboard versions, it also features a 32-bit multi-FX processor with delay and chorus. Patches can be sorted into 512 memory locations.
First Impression
It’s very welcome that Guido has responded directly to his customers’ requests here. Even though it features only one oscillator per voice, the bree6 is a fantastic-sounding analog Synthesizer with direct control and no menu-diving.
GS-Music bree6 Four Octaves Edition availability and price TBA.

Surely that logo could have been a bit larger?
The module & 37 key versions have a nice inviting feel to it, this… doesn’t.
That giant “BREE 6 FOUR OCTAVES EDITION” branding on is ugly and gaudy, distracts me from the nice simplicity at the core of the synth.
This synth looks and sounds good.
Unfortunately, I believe that ‘Four Octaves Edition’ is incorrect grammar. I believe it should be ‘Four Octave Edition’. Thanks for the coverage, Tom.
I know it’s 4-octave or four-octave but here it’s written like that on the hardware so for me that the name
Yeah, that logo is horrible. Simply removing it would make the synth look quite nice and give me somewhere to keep a small FX unit or maybe a small drum machine.
