I have a korg kaos pad. The effects are ok and there is nothing spectacular about them. Also it can be used as a X-Y midi controller.
I`d say look for something else.
There is the Kaos pad 2 aswell but ive not checked it out that much . All i know is it can sync effect to bpm but i think the bpm is derived from tap tempo function. Its got a few extra effects aswell but nothing majorly different except its appearance.
i`d say you`d be able to get the original pad for less than 100 euros
