Korg Zero 4 Firewire Mixer

Designed for high-quality digital and analog audio ZERO LIVE CONTROL MIXER delivers truly professional-spec audio. It supports 24-bit 48 kHz high-resolution audio as standard, and can support up to 24-bit 192 kHz audio that’s equivalent to DVD audio fidelity. Along with the digital domain, analog components such as the input/output circuitry and power supply have been designed with painstaking attention to high-quality sound. The internal ±18 volt power supply design delivers plenty of headroom and excellent audio quality. The mic preamps are an ultra-low impedance design by Peter Watts, a veteran designer of numerous professional mixers throughout his tenure at the Trident Corporation in the UK and as chief designer and vice president for product development at Mackie Designs in the USA. Finally, the power supply is a universal design that does not require an AC adapter, ensuring that the world-traveling professional can get to work immediately, assured of the highest level of performance.
EQ Variety
The EQ Selector is a completely new idea, providing an EQ section with eleven different simulation types. They cover needs ranging from corrective equalization to boldly creative sound-shaping, giving you a variety of EQ responses and curves, filter characteristics, and even isolator modeling that can be switched independently for each channel as needed. The stereo four-channel ZERO4 provides one unit that is shared by all channels.
FireWire control over audio and MIDI
ZERO LIVE CONTROL MIXER contains a FireWire interface that lets you process and mix audio sources digitally, at the same time as performing MIDI control. Since ZERO LIVE CONTROL MIXER contains everything else you need (audio interface, mixer, effect processor, MIDI controller), setup is simple, making it an extremely convenient choice for the mobile computer-based professional.
A full complement of effects
One particular advantage of the ZERO series is its powerful effect system. On the stereo four-channel ZERO4, there are Insert effects for independent use on each channel, plus a Master effect connected to sampler/effect buss.

The ZERO4 also contains a loop sampler that can synchronize to the BPM. This makes it easy to sample or play back loops (or one-shot samples) in perfect time with the current tempo, giving you the flexibility for complex mixes or dub mixing.
ZERO4 BPM Sampler

A complete MIDI control surface By using the dedicated "ZERO Edit" software you can freely assign MIDI messages to the faders, knobs, buttons, and toggle switches. This allows you to use the abundant hardware on the ZERO Mixers to control soft synths, DAWs, effects processors and much more. Since each channel of the mixer can be assigned to different functions you can be mixing the audio from your computer with one channel while adjusting MIDI parameters with another.
Professional-level hardware design
The crossfader of the stereo four-channel ZERO4 uses a two-rail design for excellent durability. The compact chassis is made of aluminum alloy and steel for portability and durability. The periphery of the control knobs is illuminated in two colors depicting audio mode and MIDI mode, ensuring accurate control on stage or in dim lighting.
TraktoScratchCertified
The ZERO4 and ZERO8 are amongst a small group of mixers/control surfaces with digital audio interfaces that are Certified Traktor® Scratch ready. By adding Native Instrument's Traktor® Scratch software to your Zero rig, you’re instantly able to scratch and mix any digital media on your desktop computer or laptop using your existing turntable or CD deck setup with the specially coded CD’s and records!

Ableton Live® Inside
Also included is Ableton Live 6 Korg Edition. Live 6 Korg Edition allows you to construct music intuitively and in real-time with the ZERO mixer. Additionally, the Live Lite 6 Korg Edition offers audio/MIDI recording and many editing functions. Just a few of the possibilities and advantages of this integration of products include: easily assigning software tracks to hardware I/O and channel strips and tweaking plug-in parameters as well as accessing Live control mappings with the press of a button.
13 plug-in effect processors and two virtual instruments are offered for the audio/MIDI tracks, and you can use additional VST/AudioUnits plug-in effects/virtual instruments as well. Of course you can freely operate the mixer and transport controls from the ZERO, and you can also tweak all of the virtual devices parameters. The software even includes some lessons in the Help Mode to get you started using the controllers and built-in synth!
Live Lite 6 Korg Edition offers many of the new features found in Live 6, including Multicore/Multiprocessor Support, Instrument and Effect Racks presets, Macro Controls, Project Management tools and a variety of new devices including EQ Eight, MIDI Note Length, Dynamic Tube and an improved Saturator device.
