Using Region FX in X3c with audio and executing the process as the per manual and per Cakewalk videos. Noticed several things: On older projects created in X2, V-Vocal invokes (comes up), but the yellow pitch data lines which are used to manipulates the pitch, vibrato, etc. do not appear. When I create a new project in X3, it does. Hmmmmm....
Also, I notice in X3 that when I select and create a region, it does NOT turn green, but changes to some other color like gray. Even changing the color scheme to another original Sonar preset does not seem to allow it to turn green. It still works, but I wonder why it doesn't behave as advertised. This persists in both Melodyne and V-Vocal. BTW, I am using Melodyne Editor v2.
