This Module is a prototype or in a concept phase.
Synth Voice
The Grp A1 monophonic synthesizer can be used as a stand-alone musical instrument or can be used to filter external signals through the Low Pass 18dB VCF resonant circuit. The presence of three internal signals (VCO, SUB and NOISE) ensures timbral power and ease of use. With the two Low Frequency Oscillators - LFOs (the first, integrates a Sample & Hold S&H) and the Envelope Generator ADSR, you can sculpt cyclic or transient modulation behavior.
The instrument can be powered via a USB type C cable connected to any USB 2.5A power supply.
It can also be taken out of its cabinet to be easily installed in any EuroRack modular system; it can be powered using the normal flat cables supplied with EuroRack systems.
