untangleShapePhase :: C a => Int -> a -> (a, a) -> (a, a)Source

Convert from the (shape,phase) parameter pair to the index within a wave (step) and the index of a wave (leap) in the sampled prototype tone.

For this routine it would be simpler, if shape would measure in multiples of period (we would only need a Ring instance), but for shapeLimit it is better the way it is.
