Hi, 

I'm wondering whether anyone can shed some light on the attached image.

LH of the piano here is:

{

 bf,16 (ef g8) r8

  c,16 g' c, g' bf, g'

  \clef bass

}

I have a suspicion this may have something to do with the Timing / beat moment and beat structure, but it's inconclusive. This section of the music has:

  \set Timing.baseMoment = #(ly:make-moment 1/16)

  \set Timing.beatStructure = #'( 6 6 )

There are no barline errors, but I'm seeing this in the output quite a lot: 

programming error: mis-predicted force, 108.120472 ~= 101.465263

continuing, cross fingers

programming error: mis-predicted force, 108.120472 ~= 105.654382

continuing, cross fingers

programming error: mis-predicted force, 108.120472 ~= 101.465263

continuing, cross fingers

Previously I was getting a similar issue where I had bars of 6 quavers, which were grouped in 3's -- and the middle of the second group was getting a spurious semiquaver beam. I seem to fixed it, though I'm not sure what the cause was.

Thanks in advance,

Chris

 Hi Thomas, 

 

Without tiny example everyone can guess only.

 

Yes, I appreciate that -- I wasn't  able to get a minimal working example. I was hoping for any general suggestions to fix or known bugs that might cause this.

It's ~200 bars of music, over 5 files, so if necessary I'll put it up on a Gist. 

Btw, your images are inline _not_ attached.

 

Are inlined images not OK here? ...or were you just being pedantic? ;-)
