If a RealTrack has MIDI notation, you will see an underscore in the track name (and it will show in the RealTracks picker window). However, the quality of that MIDI differs. If it's a piano track, it's probably accurate because it was recorded along with the original audio. However if it's a sax, for example, or an electric guitar, the MIDI is only an approximation. I know, because I did some of the early ones. The notes may be close, but the feel, velocity, note bends and scoops, attack etc. are all missing.
