Korg NAUTILUS AT Music Workstation - 61-Key (B-Stock)

Powering new heights of musical expression

NAUTILUS is KORG’s flagship workstation. The successor to the wildly popular KRONOS, the range now includes two new AT models. Available in 61 and 88-key versions, NAUTILUS AT introduces Aftertouch to the lineup, putting new heights of musical expression at your fingertips.

NAUTILUS AT features an expertly-tuned sound library that brings exciting aftertouch-controlled effects to the existing programs, meaning you can fully embrace the expressive capabilities of Aftertouch right out of the box.

Aftertouch, in combination with initial touch and the DYNAMICS knob (giving instant control over the changes in sound) opens a wide range of musical expression in just one instrument. Combined, these features truly unlock the full potential of nine powerful sound engines, and a vast array of other features on NAUTILUS.

NAUTILUS AT comes in two versions: an 88-key model with a premium weighted RH3 keyboard for an incredible piano feel, and a 61-key model with a light, responsive and smooth synthesizer keyboard feel.

(*) NAUTILUS-73 does not have an AT version.

Flagship model, Premium quality

NAUTILUS is manufactured in Japan to the highest levels of quality. The 88-key model uses the critically acclaimed RH-3 piano keyboard, a four-stage weighted hammer action keybed that provides an extremely realistic piano feel for even the most discerning of players. RH-3 keyboards are gradually weighted, meaning that the lower notes are heavier, and the higher notes lighter for superb playability. The 61-key NAUTILUS AT features a synthesizer keyboard with a light touch able to reproduce the most complex of performances reliably and with the smoothest feel.

As part of the wider NAUTILUS range, it’s easy to identify aftertouch-equipped models thanks to the AT mark above the NAUTILUS logo on the front panel.
