Re: Allowing a collision

[Paul Hodges]

Because although I've used it a lot, I set it up initially a year ago and had forgotten that I'd had to add the Span_stem_engraver to the PianoStaff context.  Once reminded of that, I can of course see that it can equally be added to the StaffGroup context that I'm using.

Thanks,

Paul

The real question is: why is \crossStaff inapplicable for you?
