is there any way to connect a electric drumset to a pc?
If your elcetric drumset has MIDI out, then you can certainly connect it to a PC. You have two options. If your sound card supports MIDI and also has a game/MIDI port, you can look for a cable that has MIDI connectors on one end, and a joystick (game) plug on the other. Otherwise, you can look for a MIDI/USB connector, like the Yamaha UX16. The www.gdamania.net website is a good resource for this.
Yeah that would work I think. It's been done with keyboardmania, so give the midi way a shot.
And if worse comes to worse, take a controller, a soldering gun, find someone with more know about it than I, and find if there is ummm... well they could figure it out
