NAUTILUS-61 AT Gray Limited color Gray 61 keys

Synthesizer with aftertouch

Flagship model with aftertouch and perfection.

KORG's flagship workstation, NAUTILUS, is adding two new models to the lineup, the NAUTILUS AT (AfterTouch), available in 61-key and 88-key versions.

NAUTILUS's outstanding expressiveness is now at its peak with the new aftertouch function.

NAUTILUS AT is equipped with a sound library that has been newly tuned for this model, and by adding stimulating aftertouch effects to existing programs, you can fully utilize the expressive power of aftertouch right out of the box.

The dynamics knob, which allows you to instantly control the volume and tone changes depending on the strength (velocity) of the keystrokes, is now combined with aftertouch to fully bring out the potential of NAUTILUS' nine sound engines.

The NAUTILUS AT comes in two types*: an 88-key model with a premium RH3 keyboard that pursues a piano feeling, and a 61-key model with a synth keyboard that features a light response.

*There is no AT version of the NAUTILUS-73.

Premium quality of the flagship model

NAUTILUS is manufactured at the highest level of quality in factories in Japan.

The 88-key model uses the highly acclaimed RH-3 piano keyboard. The hammer action keyboard, divided into four weight levels, provides a very realistic piano feeling even for discerning players.

This RH-3 keyboard is gradually weighted to feel heavier in the bass range and lighter in the treble range, achieving excellent playability.

On the other hand, the 61-key model is equipped with a light-touch synth keyboard, reproducing even complex phrases reliably and smoothly.

The NAUTILUS AT has the letters "AT" added to the logo on the panel, making it immediately obvious that it is a special model.
