Only a few days in, So far so good there are a lot of controls and just enough sounds to make it interesting, easy to use and it seems to be ok quality wise. if your sitting in a quiet room and you can hear a very slight hissing, its coming from the speakers on the keyboard, word ok as a midi keyboard too, would you use it in a band, I'm not so sure, middle of the road and nice to use so far ask me in 6 months :-)
