"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."

Voidcontrol MIDI Releases e7 Unofficial Editor: DAW Integration for the GS Music e7

e7 Unofficial Editor - VST3 Demo video upload by Voidcontrol MIDI

"VST3 editor for the GS e7. Real DAW automation, easily build multitimbral patches, patch library, A/B snapshots, morph, and resizable UI. Windows 10/11. Available at voidcontrolmidi.com."

Press release follows:


Voidcontrol MIDI has released the e7 Unofficial Editor, a Windows VST3 plugin that lets you control and automate the GS Music e7 from within a DAW, just like a software instrument.

The e7 is a remarkable analog polysynth with a passionate community and a genuinely unique sound, but editing it properly from a DAW has often meant menu diving on the hardware. This editor was designed to make that seamless. All 88 of the e7's parameters are on screen, laid out to mirror the front panel, with real DAW automation on every control rather than just MIDI learn.

Features include:

Full parameter control: every one of the e7's 88 parameters on one screen, with authentic readouts for oscillator tune, tempo-synced LFO rates, and waveform shapes.

Real DAW automation lanes for every parameter.

A patch librarian: browse, audition, load, rename, import and export single presets, whole banks, or full instrument backups as standard .syx files.

Multi-mode support: edit 4-part multitimbral patches with per-part level, MIDI channel, voice allocation, and key/velocity zones.

A/B snapshots with an automatable morph slider.

Two-way hardware sync: pull the synth's current edit buffer into the editor in one click, with the editor recalling its state on project load.

Init and a musical randomizer for fresh starting points.

A resizable interface with onboard help.

A standalone version is also included for use without a DAW, working as a pure hardware controller that needs no audio interface.

The editor has been tested in Ableton Live, Bitwig, Cubase, Reaper, and Studio One, with USB and 5-pin DIN MIDI, MPE support, and a one-click All Notes Off panic.

"The e7 sounds incredible. I just wanted to see all of it at once, especially the multitimbral side," said Dave of Voidcontrol MIDI.

Voidcontrol MIDI is a small US-based developer making editors for boutique and classic hardware synths. The e7 Unofficial Editor is its third release, after editors for the Roland SE-02 and Oberheim OB-6. A macOS version is under consideration.

The e7 Unofficial Editor is available now at voidcontrolmidi.com for an introductory $30 USD through July 7, 2026, after which it returns to its regular price of $40 USD.

The e7 Unofficial Editor is a third-party tool and is not affiliated with or endorsed by GS Music. "e7" is a trademark of its respective owner.

GS-e7 analog poly synth + BlueARP, EDM demo, no talking

video upload by graywolf2004ru

"A few months ago I got GS-e7 synth (7-voice analog poly) and finally managed to give it some good demo with BlueARP.
Playing various BlueARP-driven patterns, starting from barebone mono pattern to rich polyphonic pattern.
All sounds recorded directly from GS-e7, no other FX except its onboard delay (chorus was not used)."

"Music video for an instrumental song featuring the Lumatone Isomorphic Keyboard, Michael Barton Art custom 'Leo' bass, Strandberg guitar. Synth sounds from GS Music e7 [all the solo synth sounds], Hydrasynth Deluxe, sound effects with Erae Touch 2. All parts played by Sean R McKee.

All the videos I’ve seen of Lumatone were performed solo, with most exploring microtonality. I wanted to put Lumatone in a 'band' setting with a traditional Western tuning."

"Using Ableton Live software called Meridian to sequence all the synths. Great for creating Poly Rhythms. The main riff is done using the mutant feature on the Hydrasynth."

"This is IMO the best remix of my favorite House track. Manna did an amazing job, giving it that modern Melodic Techno production. Most of the synth sounds are from the GS Music e7 with lots of osc sync. I just got the Hydrasynth a few days ago so am only using it with a pad preset for now. Bass is Sub37 as usual. And I bought some crappy disco lights off Amazon lol."

"Can get some gnarly modern sounds from the e7. It has a very bright sounds and is well suited to Melodic Techno, especially those stuttering pitch bending sounds that are so popular at the moment."

Analog beauty: GS Music e7 #synthesizer

video upload by Pete Midi

"The GS Music e7 is one of the best sounding analog polysynths I ever heard. The variable stereo spread and the two sub oscillators can provide ultimate wideness & fatness that is hard to find anywhere else."

"Ended up being influenced by Trance again with the e7 doing arps. Haven't used the Mega FM for a while but it is great for dark and dubby sounds. Each note is alternately panned left and right which is cool."

"Supposed to be Melodic Techno but ended up as Trance lol. The e7 does the plucky Trance arp thing very well. Zen delay used as ever for saturation, echoes and mangling."

まるでMemorymoogの質感!? GS MUSIC e7 Poly Analog Synth from Argentina [no talking]

video upload by いーえるP@TinySymphony

"Reverb : UAD Lexicon 224

MOOG ONE よりも、Sequential TRIGON-6 よりもMemorymoogに近いと思っているアナログポリシンセ、それがこの GS MUSIC e7です。
海外フォーラムでも『e7』はmemorymoogと最も競合する音色・質感を持つとよく言われてるのですが、皆さんはどう思われましたか？

去年、5Gには黒バージョンしか無かったので、地球の裏側アルゼンチンから個人輸入しました。なんと国際送料無料だったんです!"

Googlish:

"Reverb: UAD Lexicon 224

I think this GS MUSIC e7 is an analog polyphonic synthesizer that's closer to the Memorymoog than the MOOG ONE or the Sequential TRIGON-6.
It's often said in overseas forums that the 'e7' has the most competitive sound and texture compared to the Memorymoog, but what do you all think?

GS MUSIC https://www.gsmusic.com/synth-store

Last year, only the black version of the 5G was available, so I imported it personally from Argentina on the other side of the world. And surprisingly, international shipping was free!"

Sequential Prophet-6 for the keyboard controller.
