Are the sounds crap? Well, yes and no. For that class of keyboard and at that time, they are fine, but they are also unique for almost any class of keyboard (the consumer Casio signature: unique sounds, whether you think they are crappy or not). I composed over a hundred songs with this keyboard's sounds and now find I'm nostalgic for it, and hope to have the room to have one again someday. While the sounds are hardly "pro", I pine for their very "crappiness"--I loved the synth strings, "symphony", the odd brass and trumpet sounds, and the still fairly decent pipe organ, jazz organ, and chorus sounds. The drums, though again very unique sounding, were never my favorite.

In addition to the groovy glissando button, there's a chord button that makes single key play generate chords that are connected to whatever the auto-accompaniment is doing, which could be used for a pretty fat sound, with very little effort. The auto-accompanient bass could be replaced with one you recorded on your own, and as I recall the one you recorded on your own could easily last the length of a longish song.

Most odd, to me, was the button/setting (I forget the name, someone who has one of these things please remind me)that causes the drum pattern and auto-accompaniment to vary in relation to the rhythm, speed you were playing, and there are fills and beats you can only coax out of the keyboard by playing at a certain rhythm, with that option enabled. Freaky!

And, of course, touch-sensitive keyboard. How cool is that?

This instrument has some nice features, especially the keyboard is worth of notice. But as for a stand-alone musical device I think it's utterly obsolete. You won't get much of it unless you have another sound engine. If you like to work out, take it as your controller for gigging. You'll get some heavy load on your muscles.
