Following its KAOSS PAD entrancer audio/video effect processor that has earned a major following with VJs and video artists for its intuitive touchpad interface, Korg now unleashes another bombshell --- the krossfour, a video mixer/switcher with up to four inputs. Packed into a compact body, its simple layout is optimised for realtime operation, giving you intuitive and free control over any type of video source. Video mixing and switching effects that are not possible with the KAOSS PAD entrancer alone now become possible when used together with the krossfour.

Video mixer/switcher with four-input video selector
The krossfour is a four-input video mixer/switcher that lets you input and freely mix video from sources such as DVD, video deck, video camera, or computer. Its simple layout ensures superb operability in any situation, from VJ work to video performance or video editing.

Use the crossfader to create musically appropriate video expressions
In VJ work or video performance, you can use the crossfader to easily control video sources in musically appropriate ways. You can mix using one of four different fader curves. "Normal" curve gradually mixes between channels, "No Mix" transitions by shrinking (without mixing) the channel as you move toward the center, "Center Mix" mixes the channels only in the center, and "Switcher" switches the channels in the center.

You can change between these patterns to produce a wide range of video performances. The crossfader features a blue LED indicator for excellent visibility even in dimly lit clubs.

Frame synchronizer with built-in TBC
The frame synchronizer with built-in TBC (Time Base Corrector) converts signals played back from an analog VTR etc. into stable, digitally-synchronized images, ensuring smooth and high-quality mixing.

Chroma Key and Luminance Key compositing effects
The krossfour also lets you create black or white backgrounds and provides chroma key functionality for removing the blue background portion of an image and replacing it with a different background image. The same process can be performed for luminance levels as well, removing portions of a specified brightness (luminance) and replacing them with a background image. There's also a HOLD switch that lets you freeze the input image. This is great for special effects such superimposing an object or person on a different background.

Monitor output for easy monitoring of input images
As a convenience for realtime video performance, the krossfour provides a monitor out connector in addition to the main output normally used to send the mixed video signal to a projector etc. The monitor output can be used to audition a video input source before mixing, or as a sub-output for the mixed video signal.

Use together with the KAOSS PAD entrancer for a revolutionary leap in video performance
You can experience a revolutionary leap in performance power by setting up the krossfour together with the KAOSS PAD entrancer audio/video effect processor, acclaimed for its intuitive touchpad interface. Its design, illumination, and size also match the KAOSS PAD entrancer, making the two units a great-looking combination when placed side by side.
