Many thanks. I didn't have the plugin so had to get hold of that, then work out how to import an XML file into BiaB - you don't seem to be able to do it directly into the melody track, so I had to do it as a new song, export it as midi and then import it back and it worked!
My new problem is that for some reason while I did all this, BiaB has completely changed the desktop appearance of the thing and cluttered it up with the menus for views, transport, track and toold, which i really don't need over half the screen and I can't work out how to hide them...
Edited to add, found it... Control T...

I know it's now a wonderful prog, but it was an awful lot simpler to use when it came out first with about 20 styles and nothing else! I understood it, then.

Thank you all very much for your help.
