GS Music Zeus Polyphonic Analog Synthesizer (Sneak Preview) – Synthtopia

GS Music shared this sneak preview of their upcoming Zeus synthesizer, a new polyphonic analog synth design.

Zeus is a multitimbral analog polyphonic synthesizer featuring subtractive synthesis. The sound generation is entirely analog.

Each voice has two voltage controlled oscillators (VCO), a mixer and a voltage controlled amplifier (VCA). The control signals on each voice are digitally generated by a microcontroller, which is capable of processing three low frequency oscillators (LFO) and two ADSR envelopes (EG) per voice.

The Zeus synthesizer interface was designed to be intuitive, with all the controls on the panel. It also features a graphic display to show the different parameters and curves, such as envelope shapes:


Keyboard: 49 keys, velocity sensitive with aftertouch
Polyphony: 12
Oscillators: 2 voltage-controlled analog oscillators (VCO) with sub-oscillators. Hard sync.
Oscillators waveshapes: Triangular, Saw-Tri, Sawtooth, Pulse with PWM. It is possible tomix pulse with other waveshape
Filter (VCF): 24dB/oct (4 poles) low pass filter with resonance control
Envelopes: 2* (Attack, Decay, Sustain, Release), Velocity to Attack
LFO: 3
LFO waveshapes: Triangular, Rampa up, Rampa down, Square, Sample and Hold
Effects: Chorus, Delay
Presets: TBD
Connections: MIDI IN, MIDI OUT, MIDI Thru, Audio Output (Plug 1/4” TRS balanceado), Sustain, USB, Filter CV, Amplifier CV, Audio input.
Power supply: AC 220V

Note: The demo features a Zeus synthesizer prototype. Details on pricing and availability are to come.
