I have an old guitar with a gk2 (or gk2-a I'm not sure) pickup. I want to use a laptop for my midi sounds, but I know that the gk2 has it's own wierd outputs (not standard midi). I've been googling around trying to figure out how to go about using a computer for my midi sounds and got nowhere. I'm pretty much a noob when it comes to midi so could someone let me know what I would need to buy to interface this with a computer. And would there be noticible lag in the sound?
