Greetings List,
I'm trying to understand why one syntax results in MIDI output, while
another syntax does not. I'm new to lilypond and clearly missing
something.
Below is the working case:
tagCymbals = \drummode { \voiceOne cymc4 cymc4 cymc4 cymc4 }
tagDrums = \drummode { \voiceTwo s4

Dear list,
I'm trying to control measure width using proportional spacing. And
it's not working as expected.
I created a kind of "into/out of" proportional notation wrapper:
ePUT =
#(define-music-function
(parser location num music)
(number? ly:music?)
#{
\set

Dear List,
I've been fighting a problem with horizontal spacing for some time now.

Is that possible in lilypond?
At present I have to tweak each line, and even then I can't make the
bar width the same every time.
Thanks,

Hello list,
I'm presently trying to transcribe a piece of music that has both
accented and ghost notes on the snare drum. And I've run into a few
issues:
1. Ghost notes are not particularly user friendly requiring the use
of \parenthesize. Does anyone know of a more concise way?
2. Is there

Hello list,
This might be a tall ask, but is there any way to take a complicated
music expression and after it's fully evaluated replace a note?
It's very typical to have a drum groove that lasts for many bars, but
the very first bar starts with a crash cymbal. What I would like to do

Many apologies. I didn't think an MWE was required to address the
Hello list,
I'd like to encode bar lines and line breaks into the midi output.
There are some general purpose midi control change messages that could
be abused for this purpose. These general purpose control change
messages have id's of 80-84. I don't see a way to use them in the
lilypond
e playback
based on the speed of the music and the distance (difference in x
positions) between the last note, the bar line, and the next note.
I need a different approach.

Indeed it does!
Hello List,
I'm producing muliple pngs with a single staff each. When I 'flip'
through these pngs, the staff appears to move up and down on the page.
I can set
top-system-spacing.basic-distance = #7
in my \paper block and that seems to work for the one piece I'm playing
with, but it depends

Technically, it modifies a copy of the input file. The scraping is
clunky and I don't like it though it seems necessary. The idea, I

it can add unfold repeats, layout, and midi. ly2video actually

A good place to start is a minimum working example. I can't help debug
