The Cadillac of DAW/Synth MIDI controllers. I've had it for a few years and had intended to experiment with DAW based music, it's rated top of the line for that. However, I never did get into DAW stuff, and it's just been sitting around, so time to go to someone who will use it. I can tell you that I'm a legit keyboard player, and this has the best "feel" (keybed) of any controller that I've ever played. It's a joy to play, I'm just not using it.
