Noise sweeps, up down, toneless, or with a tone....
The stuff you hear in 3 our 5 pop songs nowadays. I know, everyone says "they're easy, you can make 'em yourself..." but if you don't know how, you don't know how.
If there's anyone out there that give me a solid starting point for this, I'd be willing to pay them millions of dollars. Well, OK, maybe not...but...would really appreciate any help here.
