Notes is right on it. You are way "under-hardwared". Look at eBay and Craigslist for a USB MIDI interface. I highly recommend the M-Audio Fast Track Pro. They all do the same thing, that thing being sending a MIDI data stream back and forth. Where you get the differences is how seamlessly the interface integrates and interacts with your software. That M-Audio that I have went in like buddah! Load the driver, restart, plug in the interface, let it detect, make a chance in the hardware control panel to make it your default hardware, launch Real Band, make the innies and outies match up in Prefs, and boom. Make music.
