I added the Korg MicroArranger to my growing collection. I don't know how Korg did it..,, but their design team nailed the "sweet spot" with these mini keys. It's unreal how playable and expressive those little keys are. With less than five minutes I had no problems playing it. I can fly on this little keybed. I assume I'm adjusted to them because my wife was watching me play and her response was "how in the hell is it that you can play those baby keys as well as your big keyboards".

It's just a PA50 SD shrunk down, so I'll skip the review. Very awesome little arranger though.
