com.sun.media.sound.ModelStandardTransform
A standard transformer used in connection blocks. It expects input values to be between 0 and 1. The result of the transform is between 0 and 1 if polarity = unipolar and between -1 and 1 if polarity = bipolar. These constraints only applies to Concave, Convex and Switch transforms. @author Karl Helgason
