The Smart Pianist app's Audio to Score feature scans the songs in the music library on your smart device. It analyzes the audio, and then produces a piano score that can be customized to your liking. Change the score to be more rhythmically complex to challenge yourself, or to match the feel of the song. The Stream Lights on the CSP will intuitively light up above the correct keys to play, and will also show you when to play them. A chord chart is also produced to that you can follow along with your own voicings, if that is your preferred method of reading. If a chord or the tempo is analyzed incorrectly, quick and easy adjustments can be made. The chord information can even be converted to MIDI, allowing your CSP Clavinova to play back the chords to the song using the accompaniment Style of your choosing. Never before has technology made it so easy to learn how to play your favorite songs!
