Summer NAMM - RealTracks Artist Appearances!
If Producer Mike Harrison is recording a lot of these RealTracks in Nashville you would think by now we would have the higher quality 24bit/48khz audio rather than the 16bit/44khz from the Biab 2008 days.
Not to mention multi stem drum tracks to allow proper level mixing !

I remember upsampling some RealTracks to 24/48 and BBWin would not load them but MacBB did, though I think that should be easily fixed.

If you buy any Tracks/Loops/Samples/Virtual Instruments they all come in 24 bit.
Superior Drummer 3 has released their drum library on a 24bit 250gig hard drive.

With the low cost of hard drive storage these days you could have a 3-4T 24bit Audiophile drive.
