88 fully weighted keys with aftertouch, paired with Korgs AI sound engine to deliver rich acoustic piano, organ, pad, and synth tones. With 64-note polyphony, dual multi-effect processors, four audio outs and a well-speeded arpeggiator, it was built for professional live and studio use rather than light gigging. Its classically big hammer action makes it feel like a stage piano too.Specs:88 keys with velocity and aftertouch64-note polyphonyAI synthesis engine with approx. 18 MB ROM waveforms1,169 preset patches and 402 combination memories2 internal multi-effect processors (48 effect types)144 40 pixel back-lit LCD displayFour main line-outputs plus stereo headphone outputArpeggiator with 20 patternsIncludes great custom Nova Forge Flightcase.
