Dr Dan's comment, "if we just move on and try to replace the C_Elpas.sty with a true Real Track Style - all works as expected" fixes this here. Thank you! I had been trying to change individual tracks (i.e. swap whatever instrument track was there with something else, like an RT) while in the song's default band style, which I've always been able to do. The solution here is to change the style, then swapping can occur. Live and learn.

I removed the file from dropbox last week.

Mr Norton, regarding the email: all I know is that I did email about you this on 26 Feb

and did not get a reply or sending failure message. Perhaps there was some error further down the chain.

Anyway, got there in the end. Thanks all for comments.
