Thanks Noel,

I'll give that a try. I ended up retyping the whole thing and ir seemed to work ok, one issue I find is that you can play it through but when you save/render as a wav file sometimes bugs appear there as well.

It's a great program, until it isn't. The worst thing I find is not knowing why things muck up, there's no way to try and fix things if you don't know where to start.
