This patch features my new Venom Cross Fade 3D module. There are three CV inputs to cross fade 8 inputs arranged on a virtual cube across 3 dimensions. Each dimension can cross fade between four inputs on one cube face and four inputs on the opposite face. With each of X, Y, and Z faded to an extreme position, a single input from the 8 will be selected. With all three at 50%, each input will contribute 12.5% to the total output.

I use one polyphonic VCO Unit to generate all eight pitched sine inputs. I use the Poly Offset configured to quantize in semitones to generate the V/Oct pitches I wanted.

I use another polyphonic VCO Unit to generate 16 slow LFO signals. Nine of the LFOs are used polyphonically to generate three simultaneous dynamic mixes of the eight inputs (X,Y,Z times three).

I wanted each dimension to spend a significant time statically at one extreme or the other, and a limited time transitioning between the extremes. 5 Volts will go to one extreme, and -5 Volts the other. So I amplified the LFO signals by a factor of two, and shaped the LFO sign wave with a bit of S curve to create a sort of rounded off triangle. This results in about 33% spent transitioning, and 67% on a specific face.

I use the remaining seven LFOs, plus one borrowed from the cross fade collection, to modulate the shape of the 8 audio inputs, as well as control the depth of linear through zero feedback FM.

In a future version of the Venom plugin I will add options for the CV attenuverter scale so I don’t need to use an external VCA to get the CV scale that I wanted.
