The Rubicon is an analogue triangle core VCO that is capable of through zero frequency modulation. It
is a feature packed VCO with multiple simultaneous waveform outputs including waves that are
multiples or divisions of the base frequency.


Front Panel details


1- COARSE knob- Sets the frequency of the oscillator.

2 - LFO/VCO switch - Changes the base frequency range from very slow (LFO) to audio (VCO)

3 - FINE knob – Allows finer adjustment of the coarse frequency over a range of +/-6 semitones

4- SINE TYPE switch - SINE on the left, SIGMOID in the middle, SIGMOID at double the base
frequency on the right (sine is what you get when you push a triangle wave to a sine shaper, and
sigmoid is what you get when you push a sawtooth wave through a sine shaper -- it sounds a lot like a
saw, but a bit warmer and can be great for creating metallic sounds.

5- SYMMETRY knob - Determines the direction and magnitude of the waveform through the linear FM
circuit -- fully CW gives output at the positive base frequency, fully CCW gives output at the negative
