Re: Custom drum noteHead in define expression
Dear Thomas,
Thank you a lot. It is exactly what i was looking for and apparently no need
for adjustment in your example. All fits well.
However will try to learn how to fix the notehead position in the case i will
use other glyphs.
Thank you a lot
Best
K

Well, some scheme-knowledge is needed.
There is a scheme-tutorial in the docs. Several guile tutorials out
there, as well as the guile manual.
Best general training is reading this list, though, trying to
understand the requests and trying to solve them.
If you read someones code, try to understand what happens and why, can
it be improved and ...
The Extending Manual is not bad as well.
I remember as a starter I did several exercises, defining several
custom-markup-command, markup-list-commands, substitution functions
etc etc
Homework, like a decade ago, but I'm still learning ;)
If you try to solve an own problem searching the archives is always a
good starting point.
On topic.
There's something annoying happening while using custom-styles. I just
wrote a bug-report about it:
http://lilypond.1069038.n5.nabble.com/custom-style-custom-stencil-combination-returns-warning-tt211374.html
So with the workaround, in the bug-report as well you could do:
\version "2.19.81"
#(define mydrums '(
(bassdrummyStyle #f -1)
(snare myStyleII #f 0)
(hihat cross #f 1)
(halfopenhihat cross "halfopen" 1)
(pedalhihat xcircle "stopped"2)
(lowtom diamond #f 3)))
#(define stencil-for-my-style
(lambda (grob)
(cond
((eq? 'myStyle (ly:grob-property grob 'style))
(begin
(ly:grob-set-property! grob 'style '())
(grob-interpret-markup grob
#{
\markup \vcenter \musicglyph #"pedal.*"
#})))
((eq? 'myStyleII (ly:grob-property grob 'style))
(begin
(ly:grob-set-property! grob 'style '())
(grob-interpret-markup grob
#{
%% from http://lsr.di.unimi.it/LSR/Item?id=515
%% slightly changed
\markup \vcenter \scale #'(0.4 . 0.4) {
\combine
\translate #(cons -1.25 0) \combine
\draw-circle #0.65 #0 ##t
\override #'(thickness . 2.5) \draw-line #'(3 . -3)
\translate #(cons 1.25 0) \combine
\draw-circle #0.65 #0 ##t
\override #'(thickness . 2.5) \draw-line #'(-3 . -3)
}
#})))
(else (ly:note-head::print grob)
\new DrumStaff
\with {
drumStyleTable = #(alist->hash-table mydrums)
\override NoteHead.stencil = #stencil-for-my-style
}
\drummode {
bd8
sn
hh
hhho
hhp
toml
}
You may want to adjust stem-attachment.
I leave it as an exercise ;)

Re: Custom drum noteHead in define expression
Thanx Thomas, And thanx also for your snippet. I have already tried it and works marvelously. But concerning customizing new note heads i think checking the code itself seems necessary. Do you know if define-grobs.scm is a good place to start with ?

Probably some general help... It should be clear then that the list-argument in question is a note-head-style. Ofcourse only estabished styles will work. Not sure if it might possible to define a custom style and let the stencil-procedure rely on it. (And not the time yet to try.)
