Thanks for explaining Bob. That is a problem that to the best of my knowledge hasn't been solved. There was some mention of some software that could at least help - I think it was posted to uk.music.folk by Anahata (also known treewind here I think). A "google groups" search should find it. I could try a search myself but I realy need to get on and sort out a site problem I have. I may try to post back later if no one else comes up with a link.
