The CP33 is made for the serious musician on-the-go. Sit down with one, and the instrument becomes an extension of your hands and your musical imagination. The authentic piano voices and rich expressiveness come alive at your touch, and the sound is big enough to blast through a full band onstage - yet nuanced enough to work magic in an intimate club. Yamaha's extensive experience in crafting fine acoustic pianos helps us in creating the ultimate digital pianos. Our advanced Graded Hammer Effect (GHE) action gives all keys an authentic resistance that increases from the top register to the lower - just as on an actual acoustic piano. Which means that you can naturally pound out thunderous low notes with your left hand and let the fingers on your right dance and fly with the high notes. In crafting the authentic sound of the CP series, we used meticulously recorded stereo samples of top-quality instruments, taken at various playing strengths, and included subtle elements such as String Resonance, Stereo Sustain, and even Key-Off Samples that capture the felt dampers muting the piano strings - providing the most authentic sounding and finely nuanced acoustic piano voices possible. The CP stage pianos are also master keyboard controllers that give you full command of your gear. Play and control external tone generators. Assign different voices to different keyboard sections and create multi-textured layers of sound. Two instrument zones on the CP33 with panel sliders, let you easily tweak the level of each instrument as you play. You can also freely reassign the sliders and wheels to control other sonic characteristics of your gear, such as sound attack, decay, brightness and filter cutoff. At just under 40 lbs. the CP33 is a very compact and portable yet full size stage piano.
