The GS e7 is a subtractive synthesis polyphonic analog synthesizer. The sound generation is carried out in a total analog way. Each voice has two voltage controlled oscillators (VCO), a noise source, a mixer, a voltage controlled filter (VCF) and a voltage controlled amplifier (VCA). The control signals are digitally generated by a microcontroller, which is capable of processing three low frequency oscillators (LFO) and two envelopes (EG) of the ADSR type. In addition, it incorporates an effects processor with chorus and delay.
The GS e7 interface was designed to be simple and intuitive.
It also has MIDI connections, USB, balanced stereo audio outputs, headphone output and CV inputs.
