It does say Pro...
I'm a bit torn. It is marketed to professional artists, but the price was right for a fun bit of sound-maker to play around with. Alas, the 7-8 pieces of software you need to download, each with licence key, to register and lock to you computer, it took nearly 2 hours before I had it making its first sound. The set up with needlessly complicated and complex. The idea the kids could borrow it to play around with does not work, since all licences are tied to the machine I registered it with. The whole experience creates a hostile environment, where you the user is the enemy. But, once I had it producing sounds, they sound great and performs well. Had a good time playing around with it. Hardware great, software terrible.
So a professional artist will be fine, they are probably used to the suckage. But if you think of picking it up for a bit of fun for you and the kids, go buy some other thing instead.
Update: This MPK mini + GarageBand is a very fast way to get up and making sounds fast!
