Ok, so If you're going to the real drums picker and it says no real drums... that means your drums folder is NOT located in the default location, inside the band in a box folder.

You'll need to go back to the window menu, ReadRums settings, click the box that says "use a custom drum folder location" then click choose and tell it where your actual drum folder is.

Again, I'm working on the assumption that your drum folder is NOT in your regular Applications/BIAB folder.

Then... once you've done that... like you said.. you should just be able to make a note of your favored drum riff... type in your chords, then go into the drum picker and assign that drum riff to your tune. Then, go to realtracks picker to select your real tracks.

Also, you don't have to open every single song man! Just open whatever tune you want, (making sure that "pause until play in your prefs menu is diabled), then go to the windows menu, drum picker, then double click on a drum style. It will give you a preview of what it will sound like with that particular drum track. Again, you need to make sure you see all your real drums listed in that window. Also, just to be sure, in the upper left of the drums picker, right under filter, click on SHOW ALL.

Best of luck buddy!
