If you want to get the RealDrumCharts from the Drums folder just drag the Melody track to MID from the RealDrums SGU.
You can add them to your EZDrummer user library and find the right beat with Tap2Find or a midi sample clip quicker than having to play them in the RealDrum picker, if you have EZDrummer VST loaded in Biab it will preview them in sync with the other Biab tracks.
