<p>The DGX-660&nbsp;from&nbsp;Yamaha&nbsp;is an 88-key digital piano that features sounds based on samples from the company's CFIIIS 9' concert grand piano, a weighted keyboard with varying touch response across the key range, and Damper-Response DSP. To add to the genuine playing experience, the keyboard also provides 192-note polyphony that will easily accommodate two-handed sustained chords with heavy pedaling.</p>
