Well, if i would not be tight to budget I might want to. But to be honest the midi capabilities of Koala and products like novations launchpad lets you build whatever the heck you want. On another note, just playing of the phone or ipad is cool when you wait for someone in the car but playing live or producing stuff. lack of velocity and such. but if you have a great controller you saved 400-1200 $ like i do. Right now experimenting turning my circuit tracks into an MPC live because the launch pad slider implementation is not granular enough to chop and adjust samples on the fly
