Complete Synthesizer Voice

Two VCOs with square and ramp waveforms with depth and tune controls, each tune control is a ten turn potentiometer which allows easy setting of octave, tune and fine tune with just one knob, each one features a separate CV input for individual control or FM modulation, also features a VCO output jack for each oscillator.

Noise source with level knob, it also features a noise output jack.

Glide Effect knob, takes input from the "pitch in" input jack and affects both oscillators.

One LFO with square and triangle waveforms, it has a switcher for setting it to affect the VCO frequency or the Filter cut off, it also features an output jack.

High pass and low pass vactrol based filter with cutoff and resonance/peak control, it features an input jack to control the cut off frequency, an audio input jack and audio output jack which gives you access to the filter output signal before it goes to the VCA.

Two Envelope generators:
EG1 with decay time control, depth control and a switcher to invert the polarity of the EG1 output voltage, it is set to affect the cut off frequency of the filter and has an output jack.
EG2 with attack and release controls, set to affect the output volume (VCA), it has an output jack
Both EGs share the same input jack for the incoming gate signal.

Feedback switcher which connects the output to the mixer input for an extra harmonic boost, it also features a trimmer to set the level of feedback.

Audio input, it allows to process any external audio signal with the filter and envelopes.

The facepanel is made with 2mm high quality anodized aluminum.
