battery is so great... very easy and simple to customize kits and make your own... i bought because it is very fast to build and dev kits. I would like to see more FX besides a wierd IDMish loop/glitch effect... but this same effect allows you to use it more then a drum sampler! as a previous review stated, you can build synth instruments with it. I found it for $139 so price is way to good to be tru.Read Review
