When using the Varispeed algorithm, pitch transposition and time compression/expansion are always linked. If you apply pitch transposition to an audio clip using the Polyphonic or Rhythmic algorithms, that transposition data is stored in the metadata for the clip. Consequently, if you then switch to Varispeed, change the TCE factor, and then switch back to the original Elastic Audio algorithm, the clip will revert to the original amount of pitch shifting while maintaining the amount of time compression/expansion applied by the Varispeed algorithm.
