The Pitch Correct plugin is meant to be an alternative to classic versions of Auto-Tune. It’s best used with monophonic audio sources such as vocals.
For pitch shifting, you can use the new FX Modulator plugin. Add a Pitch Shifter effect and drag the square in the middle of the display while holding Shift. The resulting pitch shift will be shown to the top right. Formant Preservation is disabled by default
This plugin is obviously not designed for precise pitch manipulation. The final pitch will be off by 1 to 5 cents, but that should be good enough for a preview.
