Ultra-low-aliasing oscillators, using a new design.
OSC1, OSC2, Sub OSC, Noise Generator, Ring Mod, modulatable oscillator mix.
Audio input Run real-time audio through the synthesis engine, including ring mod, filters, drive circuit, amp,
and EQ.
Filters Dual multi-mode filters per voice.
Single, Serial, Parallel (with split stereo output), and 24dB(4-Pole) configurations.
Low Pass, High Pass, Band Pass, and Band Reject modes.
Multi Filter mode (Filter A only) Modulatable mix of Low Pass, High Pass, Band Pass, and dry
Driver Per-voice nonlinear driver and low boost.
Modulation 5 Envelopes, 4 per-voice LFOs, 2 Key Tracking generators, 2 AMS Mixers
Per-voice Step Sequencer: 32-step sequencer with smoothing, adjustable step duration, and
tempo synchronization.
A further evolution of Korg's acclaimed CX-3.
Phase-synchronous tonewheels (clean and vintage modes), percussion, key click, wheel brake
EX Mode Four additional, user-specified drawbars, and expanded percussion.
Built-in effects Rotary Speaker, Vibrato/Chorus, Amp with overdrive, 3 Band EQ (Treble, Mid, Bass)
Drawbar Control 9 front-panel sliders (using Tone Adjust).
Split Full control of upper and lower drawbars, even in EX mode.
Modulation 2 AMS Mixers
Includes physically modeled damping, decay, dispersion, nonlinearity, harmonics, dual pickups,
and more.
Almost all string parameters may be modulated in real-time, for unsurpassed creative and
expressive control.
String excitation Three independent excitation sources can be used simultaneously: Pluck, Noise, and PCM.
16 preset "pluck" types, with modulatable width and randomization.
Noise generator with saturation and dedicated lowpass filter.
PCM Oscillator
Excitation filter
Audio input and feedback Run real-time audio through the string, including feedback through effects.
Modeled feedback includes modulatable instrument-to-amp distance and orientation.
Filters Dual multi-mode filters per voice.
Single, Serial, Parallel (with split stereo output), and 24dB(4-Pole) configurations.
Low Pass, High Pass, Band Pass, and Band Reject modes.
Multi Filter mode (Filter A only) Modulatable mix of Low Pass, High Pass, Band Pass, and dry
Modulation 5 Envelopes, 4 per-voice LFOs, 2 Key Tracking generators, String Tracking generator, 4 AMS
Mixers.
CMT Modeling Uses Korg's CMT modeling, reproducing not only the sound but also the character and response
curve of each parameter in a way that is completely faithful to the original model.
Oscillators Ultra-low-aliasing oscillators.
VCO1, VCO2, Ring Mod, Pink and White Noise Generator.
Audio input Run real-time audio through the synthesis engine and External Signal Processor.
Filters 12dB/octave High Pass and Low Pass self-resonant filters.
ESP section: 24dB/octave Low Cut and High Cut filters, available per voice.
Patch Panel Patchable audio and modulation, at audio rates.

input, for creating a wide variety of unique filter types and
effects.
Korg's ultra-low-aliasing technology, as introduced in the HD-1.
4 velocity zones per oscillator.
Uses any mono ROM, EXs, or RAM multisamples.
PCM can either be used as an excitation signal, or layered with
the output of the string.
Dedicated 2-pole multimode filter for shaping the string
excitation.
Filter can be enabled/disabled separately for each excitation
source.
Low Pass, High Pass, Band Pass, and Band Reject modes.

New patch points: VCO 1 & 2 outputs, HPF input, LPF input and
output, VCA input, EXi Audio Input, BPF input, Mixers 1 & 2
inputs and outputs.
Dual 2-in, 1-out mixers for scaling and merging audio and/or
modulation signals, including phase inversion.
Patch "mults:" connect one output to many inputs.
