Acoustic Pitch feedback

I recently had to format my macbook pro and when i re-install everything i foudn out while i’m working that i do not have any sound when i’m at the editor while changing Pitch at vari audio or when i’m editing my midi , any suggestion ? its probably a setup issue

Turn on Acoustic Feedback (I think it is the “a” button).

Its on but there is no sound

Not sure then. Maybe a control room setting? Try turning off Control Room.

Set up your preview channels and Studio / Ouput connections correct
