A MIDI file player/game that displays the musical notes AND teaches you how to play the piano.

PianoBooster is a fun way of playing along with a musical accompaniment and at the same time learning the basics of reading musical notation.
The difference between playing along to a CD or a standard MIDI file is that PianoBooster listens and reacts to what you are playing on a MIDI keyboard.

To run Piano Booster you need a MIDI Piano Keyboard and a MIDI interface for the PC. If you don't have a MIDI keyboard you can still try out PianoBooster, using the PC keyboard ('x' is middle C), but a MIDI piano is really recommended.
