Multiple measures rests question

[Jacques Menu]

Hello,

Compressing multiple measure rests can be handled with:
        \set Score.skipBars = ##t
and:
        \compressFullBarRests
as shown below by snippets taken from the LPNR.

When and where should these be used?

Thanks for your help!

For example, multimeasure rests will be combined into a single bar if the 
context property skipBars is set to #t:

R1*2
\set Score.skipBars = ##t
R1*2

% Rest measures contracted to single measure
     \compressFullBarRests
     R1*4
     R1*24

     R1*4
