Kurzweil KA-90 – portable digital piano that combines realistic hammer-action feel, inspiring sound quality, and accessible performance features. Designed for players of all levels, it offers an authentic piano touch, intuitive controls, and a full set of accompaniment styles for both practice and live performance.
The KA-90 features an 88-key graded hammer-action keyboard with adjustable velocity sensitivity, providing a natural playing response close to an acoustic grand piano. With 128-note polyphony and 20 carefully selected sounds, including grand pianos, electric pianos, strings, and organs, this instrument delivers expressive tone for every genre. The built-in 60 demo songs make learning and demonstration easy, while the LED display ensures simple navigation of functions.
For arrangement and improvisation, the KA-90 offers 50 rhythm accompaniment styles and layering/split keyboard modes to play bass and melody simultaneously. The built-in 60-watt four-speaker system produces a rich, room-filling sound. With features like transposition, metronome, and a 1-track recorder (up to 5 songs), it’s a versatile piano for both students and performers.
Connectivity includes dual headphone outputs, line in/out, MIDI Out, and USB for connecting to a computer or external sequencer. The KA-90 can also be paired with the optional Kurzweil KAS-5 stand and triple-pedal unit for a more traditional piano setup. Compact, elegant, and powerful, the KA-90 is an ideal companion for stage, studio, or home use.
