Good points, Mario. This could work for MIDI.
However, if the RealDrums were recorded into a mix and not as individual tracks (each instrument mic'd separately) then separation is not really possible, except for EQ'ing.
Looking at some of the videos of the drums it appears that multiple mic's were used.
