GS Music Bree6, a desktop 6-voice analog polyphonic Synthesizer from Argentina initially announced at KnobCon (2024) is available now.

Just over a month ago, the finished Bree6 synthesizer from the Argentinian company GS Music was spotted at Buchla and Friends 2025. It’s the sibling of the lovely GS Music e7 polysynth from Argenina. 

It’s March 1st, and the Bree6 is officially out now and available for order. Better: the official feature set is also out.

GS Music Bree6 Official Features 

Interestingly, GS Music has decided to release the desktop (18.11” x 7.87” x 5.51) instead of the keyboard. The latter was showcased at Knobcon 2024 but no news about an official release.

Bree6 is a 6-voice polyphonic analog Synthesizer with a fully analog signal path and a super hands-on one-knob per-function user interface without menu diving. The interface houses 27 knobs, 13 buttons, and a display that ensure a fluid workflow.

GS Music Bree6 features a single VCO per voice with sawtooth and pulse waveforms and pulse width modulation. A square wave sub-oscillator per voice adds bottom end to the main oscillator.

Then, it runs in a 4-pole ladder lowpass filter with cutoff, resonance, and keyboard tracking controls—a very classic filter structure. From here, the signal flows straight into the multi-FX processor.

You can work with an ensemble-type chorus that simulates a string or vocal ensemble using multiple delay lines modulated by their dedicated LFOs. Next to this, you have a stereo delay with a maximum delay time of up to 1 second. You can set the delay time, feedback, and delay mix.

The Bree6’s modulation is also very classic. Two ADSR envelopes can modulate the filter and amplifier (VCA) section. A multi-wave LFO with up to 100Hz can be assigned to multiple destinations: oscillator mod and OSC PWM, cutoff, and VCA. 

Other modulation sources include velocity, aftertouch, and full MPE (MIDI polyphonic expression). The Bree6 has 512 memory locations for your own sounds. That is solid and should be enough.

Connectivity

On the backside, you get a power supply input, a USB port for data, a full 5-pin MIDI interface (in/out/thru), a stereo output (L/R) with mono option, and a headphone output. USB host to connect a MIDI keyboard more conveniently is unfortunately missing.

 

 

Second Impression

It’s great to see that the Bree6 is now available. I’m sticking to my first impression from 2024. I enjoy the sound quality of the synth but it is obvious that the Bree6 feature set is very minimal with a single oscillator, a lowpass filter, and classic modulations.

It’s like GS Music shows us the Argentinian answer to the Roland Juno synth but with two envelopes and a delay. For me, it’s a lovely hands-on desktop analog polysynth. However, the price of $999 is a bit difficult though, especially when you can get the Dreadbox Nymphes, from another small company, with similar features for half the price or even less.  

GS Music Bree6 is available now for $899 + $100 shipping at the official store. The Bree6 is manufactured in Argentina.

Update From January 27, 2025

Knobcon 2024 is already a few months away, and there, GS Music presented the Bree6, a new polyphonic analog Synthesizer with keys and a desktop version.

There is currently no news about the Bree6, but the desktop version was spotted at the Buchla and Friends 2025 event, and it looks neat. Maybe there will be a video from the event where we get more news of it.

Update

Article From September 11, 2024

At Knbobcon 2024, GS-Music has unveiled Bree6, a new keyboard and desktop analog polyphonic Synthesizer influenced by the e7.

Exciting synthesizers come not only from Europe or the USA but also from worldwide, including Chile, Peru, and Argentina. The latter is the homeland of the young company GS Music, which introduced the beautifully classy E7 desktop analog polysynth.

Last weekend was Knobcon 2024 (12th edition), and GS Music unveiled the Bree6, a new polysynth on their booth.

The official details are not yet known. According to YouTuber Jorb, who published a Knobcon 2024 roundup video, it’s a new 6-voice analog polyphonic Synthesizer that will be available in keyboard and desktop versions. 

Jorb says it uses many of the same ideas as the GS Music e7 desktop synth but streamlines them in a Juno-style concept. You can see that the interface is very compact but still has buttons or knobs for all functions. So a very hands-on synth.

It offers a single oscillator with saw and square waveforms plus a sub-oscillator. Then, it offers the same ladder filter as the e7 says Jorb, with cutoff,  resonance, and various modulation options.

Talking about modulation. There are two ADSR envelopes and a single multi-wave LFO. Bree6 also offers a built-in chorus and delay processors and a stereo voice panning option. Arpeggiator and sequencer are also onboard.

You can also see that GS Music Bree6 has a display for visual feedback of the parameter values, a 3-octave keyboard, and pitch/mod wheels. Buttons allow you to switch presets instantly on the fly.

First Impression

At first glance, the Bree6 is an exciting new analog poly synth. I like its compactness and hands-on design. This could be an exciting synth if you are looking for bread-and-butter analog poly sounds. From the first demo, it sounds lovely. The e7 already does that and is still an insider tip.

According to Jorb, the GS Music Bree6 will be available in November. Price is TBA.

    • I don’t mind, Its sound ms great
      Your assumption about the price is nonsense. Clearly, you have no idea about the costs involved.

  1. As I own and love an E7, I was initially really excited about Bree6, however the single oscillator per voice is a dealbreaker. Will have to wait for the next product, which hopefully is more full-fledged.

  2. The synth market: Flooded with more of the same, clones and 1-man-shows producing mediocre stuff at high prices. It’s hilarious how thousands of non-musicians buy their museum pieces to never produce any music and just noodle around and burn their cash. Never realizing, that there are MIDI controllers to fulfill the need for turning knobs of softynths one 10th the price with 10x the features. Welcome to post-consumerism. No added value.
