Arturia Keystep Pro

I've had all keysteps, and this one is the most impressive. Keys feel great, the tracks, arp, sequencer and split function are superb, especially with the led lights it looks like a sci-fi spaceship control. I've had this Keystep pro, then sold it as I've acquired a device with similar functions. I soon regretted it. So I've bought another one and not plan on selling it ever again. There is one little con of this new unit. It seems that the metal chassis of the early units was of better manufacturing quality with better painting. The new one is great also, but it seems it is slightly cheaper cast and paint.
