melodyne essential sync problem
New user of Melodyne Essential, Sonar X3 Studio. Hp 6200 quad core processor, 8GB ram, Win 7 Pro 64.
I used Melodyne Essential to process the Bass track for timing errors. When I play the whole song back, everything plays fine, all 12 or so tracks, but when I try to record a new guitar track, the Melodyne'd bass track plays back out of sync while doing the recording. If I play a different bass track that doesn't have Melodyne processing, it all plays fine during recording. I also had something similar happen with the lead vocal track, which was also processed with Melodyne.
What is the problem here ?
I got an error message every time I used to open Melodyne, saying my buffers need to be 1024 . In my Sonar Studio X3 under Audio, Preferences, Sync and Caching, File System, I can see the Playback I/O buffer size is 1024kb, and the Record I/O Buffer Size is 1024kb. Is this the correct buffer size parameter I need to be looking at ? If so, what is the problem ? Do I have to enable read and write caching ?
Thanks much,
