This guy has just joined my other studio equipment and I couldn't be happier. The tremendous amount of sounds packed into it will keep you busy for hours on end just exploring them. I've only had it for around a month and still have only scratched the surface. The 61 semi-weighted keys are smooth and easy to play. I've gotten used to the micro sized keys with my other keyboards but I have no problem at all switching back and forth. There's really not a lot to add since a lot of other reviewers have summed it up accurately. I recommend this little beast. It will blow you away! By the way,, Sweetwater is the way to go when purchasing your musical equipment. They're truly honest,,,,truly awesome!!
