You just drag the loops into RealBand, use an existing RealDrums Template or create a UserTrack Drums.

There are templates here http://realband.org/tutorial-drums1.html for RealBand or a DAW, they have Markers in the midi file guide track, you simply drag the loops in to match the markers.

UserTrack Drums the easy way here http://realband.org/tutorial-utd.html

If you have Loops it will be so easy smile
