The legacy of Korg's touchy-feely effects boxes is well known, with the first unit spicing up DJ sets and studio sessions way back in 1999.

But it's worth mentioning that this isn't a replacement to the flagship Kaoss Pad 3, but a new model that slots somewhere between the tiny KP Mini and the sampling and looping might that is the Kaoss Pad 3.

The main focus here is solely placed on effects, and the ability to achieve multiple combinations of effects and control their parameters fluidly with the touch pad in the usual Kaoss Pad style.

Twenty different effects are included, with the usual suspects such as high, band and low pass filters, distortions, delays, reverbs and modulation effects like flanging and phasing.

"The most fun to be had is to freeze parameters and swap between them like tapping a drum machine."

These sit among more modern, chaotic loop chopping, slicing and vinyl-style break effects. These are all grouped in their relevant four families on push buttons on the surface of the device.

In sync

Unboxing the unit reveals a thin and light unit that feels quite plastic and not exactly gig-ready. The soft rubber buttons for effects selection and control are more pleasant, brightly backlit and look like they'll suffer a bashing.

Each effect section is in four parts, with a freeze button below to keep each effect at the point you left it on the touch pad if required.

There's the usual FX Depth control allows to feed through a certain percentage of the original signal, and an input volume helps to keep things at the right level.

So really, technically everything is relatively simple. But, this simplicity when you consider the price might raise a few questions.

Although the KP Quad's automatic bpm calculator is fairly accurate and tap tempo can adjust when necessary, when dealing with time sensitive effects like delays, the loop slicer or beat repeat style effects, the lack of MIDI means you can't completely sync 'worry-free' in all situations.

Don't expect the automatic bpm counter to figure out anything mildly complicated, as it seems many times more inaccurate than those present on the standard issue DJ mixers and CDJs.

Quad quandaries

The quality of the effects is fine but classic sounds like the filter and flanging and phasing effects do sound a little thin.

There's a microphone input with quite an aggressive gain control on the rear, but this could work well in a live environment with a DJ or MC, or even more interestingly, to give on stage vocalists touch control over their mic effects.

But as the inputs are phono/ RCA-type connectors, it's not the greatest signal path for that kind of use. In fact the sound quality overall can be questionable if you get the input level to hot.

There is, however, a Peak LED, which will change from amber to red when you're inputting a hot signal. The touch pad has four coloured corners to indicate the weighting given to each effect, glowing brighter as you put your finger nearer.
