"GS Music is one of the most interesting boutique synthesizer companies I discovered at Superbooth 2026.

I spoke with Guido Salaya, the founder and lead engineer of GS Music, about how a small family business from Argentina grew into a company designing and manufacturing analog polyphonic synthesizers.

Their main instruments include the 7-voice GS Music e7 and the 6-voice Bree6, available as a desktop and keyboard version. At Superbooth 2026, GS Music also showed the new Bree6 Four Octave Edition - a 49-key, 4-octave version of their analog polysynth.

Featuring fantastic performance of ‪@MattJohnsonskeyspace‬ to show capabilities of Bree6.

In this interview we discuss:
why he built a synth with only one oscillator,
the philosophy behind keeping instruments simple,
how GS Music started as a hobby,
why they chose to build analog polyphonic synthesizers,
how product ideas become finished synthesizers,
the challenges of manufacturing hardware in Argentina,
what makes GS Music different from larger synth manufacturers.

If you enjoy boutique synthesizers and hearing the stories behind the people who build them, I think you’ll enjoy this conversation."

Analog Done Right // GS Music Bree 6 Keyboard

video upload by Starsky Carr

"In this in-depth demo and review, we explore the GS MUSIC Bree 6 keyboard — a 6-voice VCO-based analog synthesizer with a fully analog signal path, built-in chorus, delay, arpeggiator, and sequencer. If you love that vintage-meets-modern sound, this one might surprise you.

From raw oscillator tones to lush stereo pads and punchy basses, I break down what makes this synth special — including its unique double/triple arpeggiator modes, MPE compatibility, and rich, characterful sound that sits somewhere between classic Roland-style synths and something entirely new.

If you’re into synths like the Roland Jupiter-8 or Roland Juno-106, this is one you’ll want to hear.

🔍 What’s Covered
Sound demo (full track made entirely on the Bree 6)
Oscillator section: saw, pulse, sub oscillator
24dB analog low-pass filter with resonance & key tracking
Dual ADSR envelopes & fast modulation
Voice modes: poly, mono, unison & stereo spread
Built-in chorus & analog-style delay
Unique arpeggiator (double & triple note modes)
Sequencer workflow & performance features
MPE support & expressive control

🎛️ This isn’t just another vintage clone. The Bree 6 blends:

Raw VCO tone with modern reliability
Hands-on workflow (minimal menu diving)
A distinct character that feels alive and immediate
A surprising amount of depth for a single-oscillator synth
🎧 Who Is This For?
Analog synth lovers
Producers looking for fat, mix-ready tones
Fans of classic Roland-style sound with modern features
Anyone wanting a hands-on, inspiring instrument"

The day has arrived

We’re proud to present the Bree6 Keyboard, our first synthesizer with an integrated keyboard, designed and produced in Argentina for the world. 💙

Built on a six-voice analog architecture, it delivers a powerful and expressive sound engine capable of everything from solid basses and leads to rich, evolving pads. Now expanded with a built-in sequencer and advanced arpeggiator, it becomes a complete performance and composition tool.

With its one-knob-per-function interface, semi-weighted keybed with velocity and aftertouch, and fully analog signal path, the Bree6 Keyboard is designed for immediate, hands-on control—no menu diving.
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.
