Hi,
I’m working on a score that has a lot of arpeggios where the first note of the
6-note group of 16th notes is doubled as a dotted 4th note. Having a
macro/function to turn e.g. the pattern "f16 c a f c f,” into “<< { f4. } \\ {
f16 c a f c f, } >>”, or even more preferably “<< { f4. } \\ { f16([ c a f c
f,)] } >>” would save me a lot of typing and trouble.
What I’ve been tinkering around with is something like:
GR = #(define-music-function (parser location p1 p2 p3 p4 p5 p6)
(ly:music? ly:music? ly:music? ly:music? ly:music? ly:music?)
#{
<<
{$p1}
\\
{$p1 $p2 $p3 $p4 $p5 $p6}
>>
#})
\GR f16 c a f c f,
which results in a ton of errors (at least on LilyPond 2.18.2).
Another one I’ve tried is this:
GR = #(define-music-function (parser location p1 DUMMY DURATION p2 p3 p4 p5 p6)
(ly:pitch? string? ly:duration? ly:music? ly:music? ly:music? ly:music?
ly:music?)
#{
<<
{$p1 $DURATION}
\\
{$p1 16 $p2 $p3 $p4 $p5 $p6}
>>
#})
\GR f ”” 16 c a f c f,
And another set of errors are generated. The DUMMY is (apparently) necessary on
LilyPond 2.18.2.
Any help is appreciated!
Thanks!
