Mats: there's got to be a simpler way, but I can't get the barline to
prin otherwise. Would you mind correcting my snippet, so I can add it
to the LSR?

Hi Vit,
Mats was actually right; however you have to mix the second and the
third examples in Polymetric Notation. Besides, you have to treat each
system as a separate entity, i.e. each system has its own
\compressMusic block.

You have to know, for each system, the amount of durations? Say you have
==> four 3/4 measures on a staff = 12 quarter notes
==> on the other: one 5/8 measure, one 2/2, one 6/8 and one 4/4 => 27
eight notes.
So you have to multiply the second staff by 24/27 (which is equivalent
to 8/9) to get the same duration than on the first staff.

The measurePosition takes two arguments, which here basically
correspond to your time signature.
Maybe a Scheme function could set both the TimeSignatureFraction *and*
the measurePosition *and* the correct automatic barlines ; but every
time I try, I still have to enter each \bar manually. Can't understand
why.
Anyway, I just tried to make it simple.
