They are a lot of fun, but after about an hour of jamming/dancing around they start to show thier limitations. I play with them about once every two months for an hour or two. Playing preprogrammed patterns or writing simple patterns then jamming along with other keyboards. They help develop new motivation/excitement, although I've never recording anything with them.
