A MIDI file player that 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.

• Piano Booster follows your playing when playing along to a musical accompaniment. (If you stop then so does the music).
• Play a single hand and Piano Booster will play the other hand in time with you (and will also play the violins, the bass, the drums etc. in time with you).
• Change the speed of playback to match your playing ability.
• Transpose +/- 12 semitones without stopping the play back.
• Change the Key Signature of the piece.
• Plays any standard midi or kar file.
• Play along to any instrument in the midi file.
• Adjust the volume of the current part or the volume your piano part.
• See the accuracy of you playing.
• Change the start bar to start playing from any bar in the music. The repeat bars allows you to practice just a few difficult bars continuously.
• Timing markers are white crosses that are drawn over each note and show if you are playing ahead or behind the beat.
• A different instrument sound is used for the right and wrong notes that you play.
