Thanks jazzmandan! I tried freezing melody (and other instruments) without change. I restored to factory settings and that didn't seem to make any difference. I changed the realtracks options to favor a slower machine (I've got a relatively fast one) without change. I doublechecked my midi settings, and they seem to be right for my fasttrack and m-audio asio drivers. I'm left thinking it must be something with the file itself. I've played several songs that are demos of the various styles, changing from realtracks to midi styles, and couldn't replicate the problem. So, if someone has a minute to check out the file at jazzmandan's site, please let me know if you see something I've done wrong.

Thanks,

Bob
