...controller somehow? The only ports this particular model has in the back is the port for your power cable and an "out" jack into which you could plug a standard (large) sound jack into. Is there a way to possibly set it up as a midi controller? Maybe a piece of software or even a piece of hardware that could convert the sound coming out of the "out" jack into data usable for midi compositions? I suspect the short answer is "get a new keyboard" but if there is a way to pull it off, I'd very much like to brush the dust off the old thing and start tooling around with it.
