Welcome to the world of MIDI, now you too can spend an insane sum for professional level synth modules, mixers, amps, and speakers. I think I've spent more on my custom MIDI setup then I have on the computer, almost double lol.
I brought my shiny new Roland SC-55 to Octurbofest, then immediately realized that I had forgotten speakers and a splitter cable. Beemer and I had to run to a computer store to pick up some Logitech speakers to test out the card with.
I actually want to keep my setup nostalgic - just stereo speakers like in the old PC days. I've run retro systems through my 7.1 home theater setup and I'm actually not a huge fan of doing it that way.
I do, however, really want to buy an old 486 and run the old Roland MT-32 games like Wing Commander.
