This makes my head hurt, and my reasoning may need straightening out...
Taking a shorter example:
meter = #'((3 4) (2 4))
used with
music = {
\compoundMeter #meter
\relative c' {c1 c4}
}
suggests to me that the problem happens when the engraver doesn't
successfully reset the meter.
The log for the above values is:
bnum = 1 measurelength #<Mom 5/4>
bnum = 2 measurelength #<Mom 3/4>
bnum = 2 measurelength #<mom 1/2>
bnum = 3 measurelength #<Mom 1/2>
So measureLength of the first bar is 5/4--that is, the sum of the terms of
the compound meter, which is what was assigned by \compoundMeter #meter.
The meter has not been reset.
There needs to be a second note within the proposed first division of 3/4
for the new meter to take effect.
meter = #'((3 4) (2 4))
\relative c' {c2 c2}
The log shows that the measureLength of the first measure is reset:
bnum = 1 measurelength #<Mom 5/4>
bnum = 1 measurelength #<Mom 3/4>
bnum = 2 measurelength #<Mom 3/4>
bnum = 2 measurelength #<mom 1/2>
At the moment, my head is too tangled up to do something positive with this
information. I hope it will help, in any case.
--David.
