I posted this in your other post:
Further.. with the new Utility tracks you simply highlight a section you like in the Audio Edit of the selected RealTrack/Drum/Midi and paste it in a Utility track, just have Snap checked !
These are just extra audio/midi tracks that are selected in the Audio Edit and Piano Roll.
You will be able to generate directly in the Utility track in a future release, this will be audio or midi.
