Hi,

just one more note. Do interpolation might not always seem to be desired. Think of a parameter which controls the
pitch (of e.g. a fitchshifter). Do interpolation over the parameter-control values would mean that we implement
a glide-functionality, where the user can't control the speed of the glide.
Additionally it introduces processing overhead, as parameters usually don't change that much.
Ideas :
1.) What about if the host takes care about avoiding cracks due to parameter changes. Right after a parameter change,
it could call the plugin twice and then x-fade the outputs.
2.) Mark those parameters as non-interpolatable.

Stefan
