In [this article](http://www.soundonsound.com/sos/oct05/articles/brianeno.htm) on the making of Eno's album *Another Day On Earth*, Eno says, "When I was playing parts live into the computer I would do processing through external boxes. I'd also sometimes feed stuff out of my computer through the Kaoss Pads. There's a lot of plugin processing going on. I'd usually print the processed track inside of the computer, and then push it back in time, because when there's a lot of processing you get latency problems. I like working like that, because I can do different things with the already-processed track." Additionally, the article's sidebar lists both the Kaoss Pad Mk I and II among his equipment.more
Patton also uses a CB radio mic that is plugged into a Korg Kaoss pad for added distortion and delay effects, as well as a pair of full-size megaphones miked with a Shure Beta 98 taped inside and a radio transmitter strapped to the side of each unit. In Patton’s vocal chain, Brennan uses Avid plug-ins for reverbs, distortion, delays, tape flanging and Leslie speaker simulation. - See more at: http://www.mixonline.com/news/tours/faith-no-more/424720#sthash.lLEGuRQB.dpufmore
"The worksurface on the right seems more dedicated to rhythm creation, with a Korg Microkorg synth, Electrix Filter Factory and MOFX processors, an Akai MPC3000 sampling workstation and a Roland SH101 monosynth, a Korg Electribe RX rhythm box and two Kaoss Pad controllers (an original and a MkII model)."more
This is a brilliant bit of gear, I use it with an Electro-Harmonix RTG and it creates incredible bleepbloop sounds which can be endlessly modified and tweaked to make robotic and industrial noises which can be used over pretty much anything.
The KP1 was a great proof of concept, but it could not be sync'ed or remote-controlled by MIDI, as it only had a MIDI Out. The KP3 had tons of features, almost too many that it required sub-menus, operations that took several steps of button pressing, and a text display... all of which tended to slow down the "chaos".
Having owned ALL the Kaoss pads, the KP2 is my favorite, since 1) all the interfacing is direct, no submenus or SHIFT button shortcuts. 2) sampling is quick and dirty 3) several FX sync to clock on the MIDI Input 4) the FX programs tend to feel more "general purpose," and not specifically made for electronic dance music/dubstep/etc... 5) the "BPM Looper" program (#60) is so cool they re-created it for the KP3 "plus model"
At one point, I owned three, and I still own two...
