Some good points,
chuckebaby
you may have accidentally turned off the header:
Thanks for that Chuck, I always wondered where my header went, but preferred not seeing it so never posted question, but is there some functionality Im losing within the header by not displaying it?
Also to OP, Ive been noticing in recent project that fading didn't seem to be working, and ended up using volume automation instead. (Im still on 2017.06 update)
Regarding Melodyne region-fx, while I would normally do what I need to and then render clip, I can seeing leaving things un-rendered for some time until certain applied editing is committed to, amongst various clips and tracks.
To that end I would also say or ask for a Sonar feature that you could quickly check project to see if you have inadvertently left a region-fx open somewhere amongst all the tracks and small clips.
Lastly, I guess this should be directed to Melodyne people but always wondered why they dont have a fade tool to apply to a selected "blob" rather than just only the full volume tool.
Cheers
