And slowly add folders for Cubase to scan it must be! I probably have about 20,000 wave, midi, rx2 files. Found that if I added less than 2000 at a time for MediaBay to scan everything went ok. And then after having scanned those, I found that Cubase had to be shut down and restarted in order to properly write the MediaBay3.db and associated preference files. To just keep adding files without shutting down, even if the others were scanned, caused Cubase to become non-responsive.
It took quite a while, but once I found Cubase had to be shut down after the scan cycle, everything went smoothly. I could even add ‘my Favorites’ tabs for quick access in MediaBay. Still waiting to hear back from Steinberg help as their first generic response didn’t help.
One thing I do like about Sonar is dragging a clip into the Browser created a file automatically. I have not tried this in Cubase. I will back up all the preference files before I do.
