Re: Double time signatures

[Mats Bengtsson]

Actually, if you had specified the time signature only in the second
stave, you would have seen the same bug. Another variation of the same
bug is:

\version "2.9.11"
\score {
 <<
   \new Staff \relative c' {
     \time 8/8
     c1
     \acciaccatura c16
     c4 d4 r4 r4
   }
  
   \new Staff \relative c' {
     s1 \bar "||"
     s4 s4 r4 r4
   }
 >>
}

The logic behind the bug is that the grace note happens "before" the
bar line and that any \time or \bar or similar command happens just
at the beginning of the note that follows it, i.e. in your example the
\time command of the second stave happens "after" the grace note of
the first stave. Of course, this logic doesn't make sense musically,
it's just an indication of how the programmers have tried to teach
the computer to handle grace notes.
