PowerTracks 8 midi editing power can't come even close the power of MOTU's Digital Performer, but then again, PowerTracks is a hell of a LOT cheaper ($49 vs $499 for Digital Performer). Also, Performer is a Mac ONLY program while PowerTracks is PC only. PowerTrack's strength is in it's audio recording section, it's midi editing capability is quite limited. Still, I think you will be very happy with PowerTracks 8, especially considering the price. Btw, not only will PowerTracks 8 allow you to print chord charts, but it also figures out the chords of imported midi files.
