Just had a look on the Mac at the script not sure but I had RDUserMemos.txt as being in the Preferences folder not Data folder but the file was in the Data folder, it just gives user info in the drum picker window I think it was User Comments that you can add in the picker window.The main one you need to add to is PGALLDrumFolderNames.txt
Hmmmm...this is what I pasted into the PGAllDrumFolderNames.text file:
C:\bb\Drums\MotownShuffleGroove
Still no joy. Used the rebuild command....no joy.
