well, he didn't say he got an mpc for a controller. he said he has an mpc and wants to use it as a controller. nothing wrong with that. I'd like an mpc as the center piece of my workstation, but I just use the mpd 24 as a controller, and with half the knobs turned off since they send ghost data all the time. the pads still work great though.
but I wouldnt buy an mpd if I had an mpc, unless maybe u wanted to preserve the pads.
but yeah if he bought it for the soul purpose of a controller, of course thats not that smart, excpet it will probly last longer than most p.o.s consumer level controllers.
