GS e7 Polyphonic Analog Synthesizer Desktop Module

Crafted in Argentina as the country's first analog polyphonic synthesizer, this 7-voice desktop module delivers raw, characterful tones that stand out in a sea of polished modern polysynths.

Its subtractive analog core shines with two VCOs per voice—offering triangle, saw-tri, sawtooth, and pulse waves plus dedicated square-wave subs—complete with hard sync, autotuning in under two seconds, and a white noise generator. Everything mixes into a juicy 4-pole ladder lowpass filter with ample resonance for sweeping cuts, followed by a VCA that shapes amplitude and stereo positioning. Three LFOs, dual envelopes, and a deep mod matrix fuel endless tweaking, while onboard digital chorus and delay add polish without cluttering the pure analog signal path. MPE support, poly aftertouch, velocity sensitivity, and 4-part multitimbrality (with voice allocation, zones, and an on-screen graphic mixer) make it a connectivity champ via USB, 5-pin MIDI, CV/Gate, and balanced stereo outs. The intuitive front-panel layout keeps controls well-spaced on its compact 520 x 190 x 108 mm frame, weighing just 3.8 kg.

Players love its unbeatable value, praising the oscillator mojo for synthwave, indie pop, and lush pads that mix effortlessly—often calling it more charismatic than pricier rivals. The multitimbral mode and MPE integration get high marks for live and studio flexibility, though some note the build feels a touch rough around the edges.
