Curve is a VST3 that transforms incoming automation parameter values according to a user-defined curve. You define the curve by setting automation parameters Curve0 through Curve10, each of which specifies the height of the curve at points 0.0, 0.1, ..., 1.0, respectively. Thereafter, changing parameter In1 to any value x causes the VST to change its Out1 parameter to be the curve's value at x. For example, if you change In1 to be 0.3 then the VST changes Out1 to be the value of Curve3 (which defines the curve height at 0.3).
Incoming x values that are not exactly at a curve point are linearly interpolated. So if you send value 0.35 to In1, then Out1 will change to the average of the values of Curve3 and Curve4.
By default, Curve exports 20 in-out parameter pairs, all of which are curved according to the same function f defined by the curve points Curve0 through Curve10. The curving is sample-accurate for all changes to sent to the In and Curve parameters.
