Hey... for anyone who's been interested in what all is in the X2 "Additional Content" loops, I have created a demo for your listening.  Look for it in the SONGS Forum under the title "The X2 Additional Content Song".
 
Maybe this will save you a little time, because it does take a rather long time to sift through the nearly 3000 loops that were included in X2.
 
I hope it was OK to post this here.
 
Thanks.

if you upgraded from 8-x1, all the loops are the beatscape factory content from those versions so they'll be duplicated on your system in *multiple* locations. I'm still consolidating them and removing dupes.  I have a batch file that renames them into the <song/project>-<instrument>-<bpm>.rx2 for easier sorting.  you can download it here https://skydrive.live.com...d=5DBE71A770FCC390!301
place in the directory with the loops in it and run. 

Hey thanks swamptooth.   I upgraded from X1.  I wish the loop names had the Key when appropriate.
 
I didn't know the loops came from Beatscape....just thought they were new in X2.  Sorry.

no problem. yknow what bugs me with all the rx2 loops that you load in sonar?? they ALL load with groove clip reference notes of g# and erroneous original temo! WTF??? ALL the wav loop files (even going back to home studio 7 files) load with the right reference notes and original tempo.  fleh.
