INPUTS
1 - 1V/OCT - Controls the frequency of the VCO. 1 volt increments double the frequency of the VCO.
2 - INDEX - CV input of the VCA in the TZFM path. There is a mini attenuator on this input.
3 - TZFM - FM input that can be switched LINear or EXPonential with the switch above it. The amount of
this input is controlled by the VCA. The VCA is controlled by the TZFM knob and INDEX input.
4 - SYM - This modulates the symmetry setting, and is equivalent to turning the symmetry knob back
and forth. This is the "non-dynamic" modulation of through-zero FM. There is a mini attenuator on this
input.
5 - SOFT – Soft sync, the triangle wave reverses on the incoming sync pulse, and the attenuator sets
the probability that a pulse will cause reversing. Requires edge-y waveforms like square or sawtooth
(sawtooth is best). There is a mini attenuator on this input.
6 - HARD - hard sync input. Traditional VCO sync that resets the Rubicon when the input VCO or
Master crosses zero. Use the RESET switch above it to select if the waves will reset rising or falling.
7 - PWM - Pulse Width Modulation CV input for modulating the pulse with of the Pulse wave.
There is a mini attenuator on this input.
8 - EXP FM - input for traditional exponential FM. Does not go through zero. use for pitch bend and FM
sounds that do not have to track the 1v/oct input such as percussion. The EXP FM knob attenuates this
input. Gives 1V/octave response when the attenuator knob is turned fully CW
OUTPUTS

Frequency Sigmoid.
