I have used a lot of Korg products over the years, and this one is way below par. It's neat to have a small keyboard for travelling or for Kontakt key switches, but the NanoKEY is just way too... flacid. The keys wobble all over the place and feel worse than a cheap computer keyboard's buttons.
For key switches, sure, this'll work. But no way am I gonna play anything resembling music on these keys.
