Synthétiseur GS e7

GS Music e7 – analog polyphonic synthesizer is a 7‑voice desktop polysynth with a fully analog audio signal path and digitally controlled modulation and effects. Each of its seven voices features two analog VCOs with sub‑oscillators, a white noise source, a mixer, a 4‑pole low‑pass ladder filter and a VCA, delivering classic analog tones with modern flexibility.

The GS e7 offers 2 VCOs per voice with triangle, saw‑tri (triangle+saw), sawtooth and pulse waveforms with PWM, and you can mix the pulse wave with the other shapes. The oscillators support hard sync and an autotuning routine that quickly calibrates all voices, and an external audio input lets you run other signals through the filter. From the mixer, the sound passes into the 4‑pole ladder low‑pass filter with resonance and then into a VCA stage that also provides stereo spread per voice for a wide stereo image.

The modulation section includes 3 LFOs (triangle, ascending ramp, descending ramp, square and sample & hold) plus 2 ADSR envelope generators that can be routed to pitch, filter and more. At the end of the chain there is a stereo digital effects processor with chorus and delay, which can be synced to MIDI clock. The synth is 4‑part multitimbral, supports MPE (MIDI Polyphonic Expression), and provides 512 single presets plus 128 multi presets, all in a compact desktop format that fits easily into both studio and live rigs.
