Korg Zero4 4-Channel DJ Mixer FireWire Controller

Music is created in a dynamic process, where the artist works in a fluid fashion following their inspiration freely. The tools of the stage/studio have become more like instruments, to be played and manipulated in realtime as part of this creative process. Mixing, control, and effects all are part of the performance, and all are at the core of this revolutionary new instrument. Zero Live Control Mixer, you have just met the future.

Zero Live Control Mixer is an all-in-one "core station" designed for live performance artists, remix producers, and serious computer musicians providing a digital mixer, audio I/O, MIDI controller, and effect processor all in a single unit. Each channel can be switched between sources such as a turntable, CD player, microphone, computer, instrument, MIDI controller, or MIDI controller + audio to implement a sophisticated live mixing setup with the simplicity of a FireWire connection. This gives you an incredibly powerful and flexible tool designed specifically for live performance and remix production.

Two models are available: ZERO4 is a four-channel version designed for the needs of the modern DJ, and ZERO8 is an eight-channel version covering the needs of advanced laptop musicians, studio remixers and DJs requiring more channels.

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 ultra-low impedance. The mic preamps are designed 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.

ZERO4 BPM Sampler
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.

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.
