Changing iTunes default Library

Willie - on output changing back to internal speakers....YES. Every once in a while, I'll have to reset the output setting either in MIDI or in BitPerfect preferences. Sometimes BitPerfect does not seem to "see" the V-Link 192 or when listening to headphones, the DragonFly. Occasionally the device is not even listed in the Output selection popup and I have to restart BitPerfect and iTunes. Doesn't happen all that often so not that big a deal. Not having much other experience, I just sort of accept this as more or less normal. Let us know if you learn anything. Maybe if you post to Apple support you will learn something.

Willie - Not ALWAYS, but things seems to work pretty consistently for me with
library file stored on external hard drive (along with a copy of the iTunes folder).
I do occasionally have to respond to a popup about BitPerfect or iTunes not being
able to find the library and have to click NEXT on a popup to give permission to
search for the library. Most of the time (8 out of 10?), Bitperfect launches iTunes
and the library comes up without any popups. I do "Quit" out of
iTunes and BitPerfect when shutting down for the evening. Power outages and
especially when the power comes back on are the worst. Sorry I can't be more
helpful.

Willie - Sounds like progress. If problems persist (I don't have my library sorted or tagged) the Mac support forums can be very helpful on matters like this. ALSO - if by chance your NAS is something offered on Amazon, the reviews and comments section under the product listing will allow you to post a question. Never, know, might get some informed advice from that quarter. Good luck.

Glad you got it fixed. Not sure I had much to do with it, however
