FWIW, my 9 YO kid uses Ableton Live for that genre, it works for him, and he says it is intuitive. Kinda funny to watch the G.C. guys eyes get as big as sewer lids when they see him in action. He makes my head spin sometimes too and I have my own studio and program aircraft flight software for my day gig. Of course, I am biased, but he's awesome! I dreamed of someday having a kid I could jam with, and I have one, he'll play the drums with me, the harmonica, the keys, it's crazy! His twin sister can sing like there's no tomorrow, when she sings at our shows the kids come out of the wood work and surround her like a celebrity - totally repeatable and nuts!
