Knobcon 2024: GS Music Showcases E7 and Bree6 Synthesizers

video upload by sonicstate

Pulled this one out of this playlist as GS Music supports the site (thank you GS Music!), and their new compact Bree6 keyboard synthesizer shouldn't be missed. The Bree6 made its first appearance in Jorb's best of Knobcon video posted here.

"We caught up with Guido from GS Music to discuss his flagship synthesizer, the E7, and a new entry, the bree6. The E7 is a seven-voice analog polyphonic synthesizer featuring two oscillators with sub-oscillators, a four-pole ladder filter, VCA, and built-in chorus and delay. It supports four-part multi-timbrality and MPE (MIDI Polyphonic Expression).

The E7's oscillators include a new temperature compensation circuit ensuring consistent tuning.

Guido also showed us the new bree6, a six-voice analog polyphonic synth equipped with a single oscillator per voice, pulse width modulation, the same ladder filter as the E7, and additional features like an arpeggiator and sequencer. The distinctive "polystereo" panning mode was highlighted, providing a wider stereo spread for the voices. Both models will be available through GS Music's website and various dealers worldwide - the bree 6 should be released around November.

The signal path in the Bree6 is entirely analog, comprising 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, featuring one LFO and two ADSR-type envelope generators. It also features a stereo digital effects processor with delay and chorus.

Oscillators
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.

GS e7 - Analog Poly Synth with Ladder Filter | Full Track

video upload by Mamotreco

"Music track made fully with the GS Music e7 polyphonic analog synthesizer from Argentina. All sounds apart from drums are made with the e7, multitracked in Ableton Live 11. I originally composed the song with a VST synth, but subsequently rerecorded all the midi tracks with the E7 from scratch.

I received the synth earlier this week and recorded the track fairly quickly - I've since had time to create nicer sounding patches which I look forward to using in future tracks.

#gsmusic #gse7 #synth

The GS Music e7 is a 7 voice analog polysynth with 2 VCOs and a ladder filter. It has a very analog sound despite being a modern and stable synth design.

GS Music Bree6 // Small Simple and Sublime

video upload by Starsky Carr

https://www.gsmusic.com/

"Sound is everything... and the GS MUSIC Bree6 doesn't fail to deliver. There's an intangible quality to the tone of their synths. The GS MUSIC e7 bing their first offering, that bowled me off my feet when I first got my hands on it.

This was first announced in NAMM 2024, so it's took a while to get to me - and it was worth the wait. Its a single VCO 6 voice polysynth with a 24dB LP filter and all analog signal path ... so it's in the same ball park as Juno's except this is a VCO, not a DCO, and has a different flavour.

Importantly for a boutique synth manufacturer, this feels great to use - its got a knob per function interface thats so intuitive and easy to navigate you'll be an expert in minutes!"
