The Yamaha YTP 210 is a portable grand, that with the push of a button converts to a stereo-sampled piano for a realistic piano sound. This keyboard comes equipped with the Yamaha Education Suite V5, with 102 built-in songs for users to learn to play, while teaching timing, waiting and grading, with a chord dictionary. It comes with Real Stereo sound quality, with stereo-sampling technology, not just 2 speakers like previous models. This is a higher end model becuase it features a 32 note polyphony instead of the custom 12-note polyphony, and it will play back 16 different parts or sounds at once (the 16-part multi-timbrel).
Feature upgrades as seen in the model YPT 220 include a reverb effect with 9 reverb types to add a richer sound to the performance. If upgrading to the YPT 310 model, one would have added features like 482 voices (instead of 375), and a 2-track sequencer and Flash ROM for storage.
