Korg Nautilus 88 AT Gray Specifications

Keyboard

• • 88 Keys:RH3 (Real Weighted Hammer Action 3), A – C (Velocity sensitive and aftertouch supported).

Synthesis Types

• • • SGX-2 Premium Piano (Acoustic Piano)
    • EP-1 MDS Electric Piano (Electric Piano)
    • HD-1 High Definition Synthesizer (PCM)
    • AL-1 Analog Synthesizer (Analog Modeling)
    • CX-3 Tonewheel Organ (Tonewheel Organ Modeling)
    • STR-1 Plucked String (Physical Modeling)

Maximum Polyphony*1*2

• • • SGX-2: 100 voices*3
    • EP-1: 104 voices
    • HD-1: 140 voices
    • AL-1: 80 voices
    • CX-3: 200 voices
    • STR-1: 40 voices
    • MOD-7: 52 voices
    • MS-20EX: 40 voices
    • PolysixEX: 180 voices

*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)
