Um, most keyboards (the musical kind) can... You just need the right cable, I think.
Gotta have *a* keyboard first. My sister ran off with our old one. And she probably pawned it for drugs or something-_- That or I'm hallucinating and we never had one at all, although I thought we did.

DJZen, I know of a 'ffmedley.mid' that's about 20 minutes long with songs from 1-6. . . It's not bad, but probably not what you're thinking of
