Re: Unconventional score and unwanted stray staff lines

[Karim Haddad]

Dear David,

Lately I had a similar issue with a multi-tempi and multi-metered ensemble 
score.
However the strayed clefs and staves where not on all instruments. I suspect it 
does have to do with internal timing lilypond calculations.
My workaround was to put at each end of a part where this occurs, this :

%here is the closing bar :
\once \set Staff.whichBar = "|."
% these are to stop the running staff and "phantom" clef and instrument name 
going on .... :

\override Staff.Clef.stencil=##f
\set Staff.shortInstrumentName = #""
\stopStaff

Hope this helps.

Best
Karim
