At just 17lbs, the ProKeys 88sx digital stage piano delivers excellent sound in a package so light that you can carry it under one arm. Its must-have complement of instruments—grand piano, electric pianos, organ and clav—sound better than anything in its price range. The piano's semi-weighted action also delivers the best feel you can get without the added cost and weight of hammer action. Two stereo headphone jacks are perfect for private practice or teaching. USB MIDI interface and pitch/mod wheels combine with other features to make it a great MIDI controller as well. If you want a pristine-sounding digital stage piano that feels great to both your fingers and your back, the ProKeys 88sx is for you.
