I received the Xylosynth yesterday and was perplexed as to whether I should play it or place it in an art gallery and charge admission. What a beautiful work of art and well crafted instrument combined. The best non-esthetic feature for me is the real-time length of note control using the analogue control knob. The second best feature for me is that because it looks more like high quality furniture than an instrument, my wife is more receptive to it being set up in our bedroom, where I practice. Thank you very much for producing such a fine instrument.- Aquah Beale
