GS e7 Analog Polyphonic Synthesizer (Blue)

The GS e7 Analog Polyphonic Synthesizer (Blue) is a polyphonic analog synthesizer with VCOs, VCF, LFOs, effects, 512 programs, 128 multi-presets, MIDI In/Out/Thru, USB port, Pitch CV, Cutoff CV, Gain CV, Ext input, audio output L/Mono, R, balanced 1/4" TRS, and headphone output.

The GS e7 synthesizer features a fully analog signal path. Each voice has two voltage-controlled oscillators (VCOs), a noise source, a mixer, a voltage-controlled filter (VCF), and a voltage-controlled amplifier (VCA). Control signals are generated digitally by a microcontroller that can handle three low-frequency oscillators (LFOs) and two ADSR envelope generators (EGs). Users can creatively enhance the audio signal using chorus and delay effects.

The synthesizer is housed in a stylish metal case and features an intuitive control panel on the front for quick and easy sound creation. The instrument excels in both studio and live performances thanks to its extensive MIDI connectivity, as well as a USB port, balanced stereo audio outputs, headphone output, and CV inputs.
