I was given an M Audio X Session pro a few weeks ago. It looks and feels like a toy, but it works. I've not assigned all the available buttons to functions, just trad hi-mids-lows and volume on the slider, which gives me 10 other buttons and a crossfader to find a use for if I can be bothered; beat repeat and delay, I guess. I'm going to have a look at mixing w/ filters soon, just hi's and lows on each channel, which would free up 4 more knobs, though I'm in no hurry to use them.
