Has anybody tried or bought the Post Musical Instruments Grandioso
Bosendorfer 290 Virtual Instrument (uses a Kontakt type interface)?  If so,
do you like it?  Is it a resourse or memory hog?  Does it sit well in an
orchestral piece, rock piece, etc?  Any problems.

Does anybody have another high end piano library that they prefer?

Thanks for any replies.

James
