Cant figure out where this should go

Well, according to Wikipedia it's a musical instrument, but it has buttons like an electronic keyboard. So I put it there.

But you're right, it's a bit interesting. We should probably have a MIDI Instrument category at some point, or maybe we'll have enough of these things we can have a Music Production Center category someday. I think it's important not to categorize devices too far up in the hierarchy—it would really confuse newcomers to see an MPC2000XL next to a 'Microphone' or 'Electronic Keyboard' category. That's why I went with Electronic Keyboard.
