What version of SONAR are you running. I can hear the notes just fine when moving notes around as a region effect. This was the case for me in both X3 and Platinum.
I can try to reproduce this for you later this afternoon if you still have issues. Keep us posted.
I'm using X3 Producer. And maybe I'm using the wrong terminology, but I meant when you insert Melodyne into a clip, (clip fx?), I don't hear any sounds when moving the "blobs" from note to note. I only hear them when I use Melodyne as a track fx.
As I said, it's possible I'm doing something wrong, but that has been the results for me.
