You guys rock!
In the Sonar documentation (which IS pretty amazing, they don't really go into the overall, big picture of how Sonar deals with things. They say how, but not why. So, I'm left with partial knowledge about alot of subjects.
So, to summarize...
 
-Region FX lets you access Melodyne.
-Once you use ANY Region FX, you need to "render" it. True?
-Once a clip has been "rendered" you need to Bounce it to Clips in order to relieve the PC of having to process the clip in real time. True?
-Once you've Bounced it to Clips, you need to either Delete or Freeze the original, non-Bounced Melodyne-ized clip.
True?
Thanks again people!
