super synthesis tvca price : tbd

tvca is a 2-input vca built around the lm13700, taking advantage of its characteristic hyperbolic tangent transfer function to yield delicious distortion. the dist slider is just an attenuator on the input of the vca, with something close to unity gain at the bottom and "major crunchy squashing" at the top. the rest works as a standard vca, with two separate inputs with their own associated attenuators.

features:
in: dc-coupled signal inputs with associated level controls.
cv: the vca's cv input. 0v is closed, 5v is fully open.
dist: distortion amount.
init: initial gain. an offset to the cv input or manual control of vca gain.
