Wow. Thats perfect. I'm not sure what you meant about the global
statement, this is my first time trying to program anything, but I'll
look through the docs and see if I find something out. Now, I just
have figure out how this codes works and have it correspond to a clock
function on a display, which gives the bpm.

Thanks, I was getting rather frustrated. I'll post back if I get
stumped.
