I went to the web page, and I feel that you need to provide more information about Harmony. Right now, all I can do is download the trial version. That's a big step to take without knowing more. For example, I have found over the years that loading a new program can interfere with existing programs, especially music programs.

Some visitors to the site won't even know that Harmony is a music program.

Guys - enough about the flatulence and the bicycle clips. Pavane has worked hard on his program, and de-railing this thread isn't fair.
