Ewwww... Soundblaster for Recording Songs?
I'd recommend just going for an upgrade. My Soundblaster sounds horrible, I have to record everything on my keyboard and move it over via USB. I've been saving up for a good audio interface, there's quite a few out there. Don't dip under 600 bucks.
If you'd like, I'll try pointing you out.
I'll see how I can help you, though. Gimme a little time, and it'd help if I could get specific model, etc.
