The Yamaha PSR-SX900 Chord Looper enables you to record a chord sequence and play it back, freeing your left hand from playing chords and providing new opportunities to further enhance your performance.
But the Software License Agreement for the Chord Tracker app says the data received by means of the software "may not be *duplicated, transferred,* or distributed, or played back for listeners in public without permission from the copyright owner." So, assuming we're indeed seeing the data being transferred and duplicated to the Chord Looper in this video, is that why the chosen song is 'Danny Boy', which is safely in the public domain?
