So...
-copied all existing files from /Library/Application Support/IK Multimedia to USB drive (except my T-Racks and Amplitube stuff
-set the disk path in ST3 to USB/IK Multimedia (put everything in there)
-downloaded and installed Syntronik, samples to USB drive
-hit the arrow for rebuilding database in SampleTank 3 stand alone
results:
-all of my Syntronik shows in ST3, but gives error: failed to load
-none of my previous ST3, SampleTron, etc shows up at all (it all previously worked)
When I reset the Disk Path back to the original folder on my Macbook HD, nothing shows up either. What have I done wrong?
I...even looked at the manual...I feel so dirty
edit: In Main Stage I can use Syntronik (shows up separately in from ST3) and it works. But ST3 in Main Stage still does not work--same as the stand alone.
