Kurzweil AMS-SP6 88-Key Weighted Stage Piano

The Kurzweil SP6 is an 88-key stage piano built for performing musicians who need professional-quality sound and responsive touch in a portable format. Its fully-weighted hammer action keybed provides the graduated resistance and key travel that pianists expect from an acoustic instrument, making it suitable for classical repertoire as well as contemporary performance. The onboard 2GB sound library draws from Kurzweil's acclaimed flagship instruments, covering acoustic and electric pianos, organs, strings, brass, and a variety of other orchestral and contemporary timbres, all optimized for expressive live playing.

Where the SP6 particularly stands out is in its performance control layout. Twenty programmable controllers — including knobs, buttons, and sliders — give players real-time access to sound parameters, effects, and layer adjustments without navigating through menus mid-performance. Four built-in arpeggiators open up rhythmic and melodic possibilities for electronic and contemporary styles. Onboard effects processing means sounds can be shaped and polished without external gear. At 40 pounds and measuring 52 x 15 x 6 inches, the SP6 strikes a practical balance between full-size weighted action and stage portability, though musicians will need to supply their own stand, pedals, and amplification.
