Hi,
I think there is a crash-bug in the Audio->Process->Pitchshift function.
- Take an audio file/loop/wav
- Select it
- Select : Menu->Audio->Process->Pitchshift
- Now this is important : Change root note/pitch to something else than C
- Leave MPEX 4 preset as is, -> Mpex Mix fast formant.
- Click Process -> CRASH CUBASE.
Workaround : Choose Mpex Poly complex Formant it works.
