Yes, you could pitch it up or down to any compatible key, but limitations include:
- In the DJ context, "pitch" usually means changes in speed where a songs key and BPM are normally linked. Changing BPM by 6% normally changes a key by one semitone. With key controllers, you may adjust speed and key independently. You could theoretically adjust the key of a song up or down six semitones to any point around the Easymix Circle. This would be like moving up or down six keys on a piano keyboard.
- Adjusting with key controllers creates distortion, with the worst distortion happening the more you adjust the key. Moving only a few percent may have minimal side effects, while larger shifts will sound worse. This depends on the audio quality of the key controller.
- Pitch adjustment without key controllers moves BPM and key together, in a lockstep. While you avoid key controller distortion, these shifts may produce chipmunk or Darth Vader vocal effects when done to excess. You can pitch shift instrumental tracks much more easily than vocal tracks because there are few "normal" instrumental sounds aside from percussion.
