Master keyboard from Z-Key series that was designed for discerning users who rate quality over price. It incorporates a completely redesigned, professional key-bed with 61 Zenith keys with velocity sensitivity and after-touch, resulting in better, more consistent semi-weighted action. The Zenith keys are the most comfortable piano-style keys and were developed after several years of research by CME. Each key is individual, not manufactured as part of a block, so that they can be mounted individually. The key-bed also provides a choice of use with velocity curve and after-touch curve. The keyboard features pitch bend and modulation wheels, an assignable data dial, a standby button, MIDI output, sustain pedal jack socket and Octave +/- buttons. It is USB bus-powered and class-compliant with Windows XP/Vista/7 and Mac OS X. Alternatively it can be powered by Mains/USB converter (not included) if not connected to PC. The casing f the keyboard is manufactured in high quality aluminium for extra strength and the end panels in piano-lacquered polished ebony.
