I actually can't get ANY sound out of my MPK, I've tried using it with the ableton live lite 6 that came with the mpk and with fl studio and can't get anything. I'm in the process of getting Reason 4.0 but I have a feeling even when I do get it, it still won't work. As far as I know it's connected fine to my computer, when I plugged it in it installed the driver and obviously it's powered by USB so I know it's reading it. HELP!
