Bug-busting!

I killed a bug today.

When converting from tick count since the beginning of the file to time since the beginning of the file, I was converting times without accounting for the change in tempo, thus resulting in a considerable portion of the piece being scrambled without my being able to tell what was wrong, since I can't play the output yet, not having the sound-creation actually in place.

Oops.

Well, at least I fixed it.
