[LAU] showing piano style double staves in Rosegarden / Lilypond

Hello, Does anyone know if there's a way to display recorded midi tracks in Rosegarden with a double staff, treble and bass clef, the way piano music is usually written? I'm trying to help out a friend of mine who wants to be able to play stuff on his midi keyboard and have it automatically written into music notation, both as a way of learning notation himself and for communicating with other musicians. We have managed to get rosegarden to record midi from the keyboard into a track, and display it or export it to lilypond, but the problem is it can only show a single stave at once, with either a bass or treble clef but not both. The rosegarden faq mentions a document which is supposed to explain how to get rosegarden to show a double piano style stave, but it's moved or been taken down and I can't find the link. Thanks for any help with this. andy
