It retains the same feature set as the standard NAUTILUS AT but adds an enhanced stage presence: this 88-key RH3-action version features black wooden side panels for a refined look. Beneath the panel are KORG’s nine synthesis engines (SGX-2, EP-1, CX-3, AL-1, MOD-7, STR-1, HD-1, MS-20EX, and PolysixEX), a 7” TouchView display, Set List mode with SST (Smooth Sound Transition) , an open sampling system, and a professional MIDI/audio sequencer.
