That's exactly what brought me to this program! I was searching on the internet for USB footswitches, to control the shooter game Return to Castle Wolfenstein. Most of the products were either too expensive or not available over here (the Netherlands).
Then I thought, hey I have this Roland SPD-11 pad controller with a footswitch, maybe I can somehow use that and then i found this program through this topic:

Too bad I don't have the right cables over here to connect my SPD to my soundcard, otherwise I could have tried it right away. If it works well I think I'll add another footswitch!
