With Pro Tools 10.3, Superior Drummer 2,3, I have SHUFFLE mode set, and I can drag Groove elements (Intro,Verse,Chorus, etc) into an instrument track and they snap together just great. But when I drag a Fill into Pro Tools, it snaps it to the END of the last groove I pulled over. How do you snap the Fill into the right place inside the groove clip? Also the Fills drag over with 1/2 of the empty(silent) space – why does bring over that empty space with it?
