OK, looks like build 462 fixed it!

I had a slight lag from using the Creative Asio drivers but I switched to ASIO 4 All and that seems to be good. I think any apparent lag at this point is probably just from me not being used to the action on the keyboard.

Thanks, guys! I guess I just had to wait for the right build. =P

But y'all taught me a lot so: thanks again!
