Joe, let's talk about your GI-20. I have a GI-10, so I am familiar with its functions. It's pretty straightforward.

All you are concerned with is the MIDI Out, from which you will run a cable to either the MIDI In of a hardware sound module, or to the MIDI In of your PreSonus device, which should be selected as your MIDI input in order to drive your soft synths. If the PreSonus doesn't have a five-pin MIDI In port you will need another device in its place.

If you're on a budget, MIDI cables are cheap and easy to build. The connectors have five pins, but MIDI only uses three conductors which do not require shielding. Radio Shack parts are adequate, and you can make any length you need.
