The Korena take
KORG’s 88-key NAUTILUS is a music workstation that combines nine onboard sound engines with more than 2,200 preset sounds. It covers piano, electric piano, organ, analog-modeling, physical-modeling, and digital-synthesis work while also supporting sampling, sequencing, and audio recording. The 7-inch TouchView display, six real-time knobs, and four programmable knob templates keep key controls accessible during a performance or production session. For arranging complete songs, it provides a 16-track MIDI sequencer, 16-track audio recorder, Set List mode, seamless sound transitions, and USB/MIDI connectivity.

- *1
- In rare cases, when a large number of processor-intensive effects are active simultaneously (for instance, more than 14 O-Verbs), polyphony may be slightly reduced. *2: A portion of the multicore processor in KRONOS is devoted to generating voices, and a separate portion is devoted to generating effects. KRONOS dynamically allocates the voice processing power between the engines as necessary. The quoted maximum numbers of voices apply when 100% of the voice processing power is devoted to a single engine. *3: 100 dual-stereo notes (equivalent to 400 mono voices)
