I don’t understand, I have probably misunderstood something
If I have a piece of audio and I want to change the pitch, I use the Split tool to cut the range.
Select that piece and in the Info line I use Transpose and/or Fine-Tune, and make sure the Algorithm is set to Elastique pro Time or Pitch (Tape will not work) or their Formant versions.
That does not do any timestretch, and use it all the time on vocals to create harmonies, that I often send to the reverb only.
