New GS Apollo I Monophonic Desktop Synthesizer from Argentina

Published on Oct 18, 2018 GS Music

"The GS Apollo I is an analog synthesizer, monophonic, of subtractive synthesis. The generation of the sound is done in an entirely analogical way, with two oscillators controlled by voltage (VCO), a mixer (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.

The Gs Apollo I interface was designed to be simple and intuitive. It has 18 knobs and 3 buttons. It allows to generate a great variety of sounds.


Polyphony: Monophonic, priority to the last note
Oscillators: 2 voltage-controlled analog oscillators (VCO) with sub-oscillators.
Oscillator Waveforms: Triangular, Saw-Tri, Sawtooth, Pulse
Filter (VCF): Low pass filter of 24dB / Oct (4 poles) with resonance control.
Envelopes: 2 * (Attack, Decay, Sustain, Release)
LFO: 3 **
LFO waveforms: Triangular, Ramp up, Down ramp, Square
Presets: 8
Connections: MIDI IN, MIDI OUT, MIDI Thru, Audio Output (Plug 1/4 "TRS balanced)
Power: DC 12V 1A
Dimensions: 280mm x 140mm x 81mm
Weight: 1.6 kg
Dimensions (with packaging): 330mm x 220mm x 135mm
Weight (with packaging): 2.0 kg
* From the panel it is only possible to control both envelopes simultaneously. To control them independently you must use the corresponding MIDI CC.
** Only one LFO is controllable from the panel. To access the other LFOs, the corresponding MIDI CC must be used."

The Apollo 1 is expected to ship November 3rd, 2018 for 19000 ARS Argentine Pesos, which comes out to roughly $520 US.
