I liked this effects unit so much I bought it twice. A few years ago I bought the Korg Kaoss KP2. I loved the effects and the control I had with the pad interface. I also used the sample loops all the time. I still use it in my live set up today.
Then the KP3 came out and it had a bunch of new effects patches that looked like I could use them as well, but I couldn't justify spending that much on another effect. Then they released the Mini kp.
The Mini Kp has the same patches as the KP3, but is much smaller and is battery powered. I love it. I use both live, but if I want a smaller set up I can use just the mini. It has some real cool granular patches and some delay patches I use all the time.
