Hi Paul,
David already wrote about convert-ly...
Let me provide some test-code and the relevant output of it for
2.19.84, 2.20.0 and 2.21.0
#(use-modules (srfi srfi-39)
(scm display-lily))
#(define (make-display-pair expr)
(list
expr
(if (defined? expr)
(let ((evaled-expr (primitive-eval expr)))
(if (procedure? evaled-expr)
evaled-expr
(music->lily-string evaled-expr)
))
(format #f "undefined in ~a" (lilypond-version)))))
#(format #t "For ~a:\n~y"
(lilypond-version)
(list
(make-display-pair 'compressMMRests)
(make-display-pair 'compressFullBarRests)
(make-display-pair 'expandFullBarRests)
(make-display-pair 'compressEmptyMeasures)
(make-display-pair 'expandEmptyMeasures)))
###################
For 2.19.84:
((compressMMRests
#<Music function #<procedure #f (music)>>)
(compressFullBarRests
"\\set Score.skipBars = ##t
")
(expandFullBarRests
"\\set Score.skipBars = ##f
")
(compressEmptyMeasures "undefined in 2.19.84")
(expandEmptyMeasures "undefined in 2.19.84"))
#########################
For 2.20.0:
((compressMMRests
#<Music function #<procedure #f (music)>>)
(compressFullBarRests
"\\set Score.skipBars = ##t
")
(expandFullBarRests
"\\set Score.skipBars = ##f
")
(compressEmptyMeasures "undefined in 2.20.0")
(expandEmptyMeasures "undefined in 2.20.0"))
###################
For 2.21.1:
((compressMMRests
#<Music function #<procedure #f (music)>>)
(compressFullBarRests "undefined in 2.21.1")
(expandFullBarRests "undefined in 2.21.1")
(compressEmptyMeasures
"\\set Score.skipBars = ##t
")
(expandEmptyMeasures
"\\set Score.skipBars = ##f
"))

As you can see compressMMRests is always a music-fuction _requiring_ a
music-argument.
Thus there's no chance any of your initial examples ever worked!
The first example omits any music-argument, thus the error.
The second example gives s1*28 as a musical argument, thus the
function compressMMRests sees no MultiMeasureRest and ofcourse does
nothing with s1*28
Did you confuse compressMMRests with compressFullBarRests (up to
2.20.0) and/or compressEmptyMeasures (since 2.21.0)?
Cheers,
Harm
