Thanks Mister M.

My feeling has been that Variphrase has been underestimated here. Most of us do not want to construct complex multisamples. Variphrase gives us a way to make user samples extend over a wider range while keeping the timing constant. This can be useful for all types of samples, but particularly vocal and natural sounds. There is a vast library of .wav files on the Internet that would be more musically useful on a Variphrase machine.
