Hi,
A little request for feedback from Scheme power users:
Consider the following snippet from David K.
\version "2.23.11"
#(define-macro (pattern args result)
`(define-music-function (parser location ,@args) ,(make-list (length
args) 'ly:music?)
#{ $@(list ,@result) #}))

Apologies: I got confused in my own thinking and thought this change
would simplify more than it can do. Consider this request moot.
Sorry for the noise.

Ah! It read like you did propose that. Hence my screed. Phew!

Where is the code that actually draws a circle stencil? I am interested
to see if it is done with Bezier curve techniques and to study that. I
could not seem to find it in the scm area.

Well I suppose it is actually postscript. So I had better look at the
full source?

HI;
first repeat at low dynamic; next repeat at higher dynamic; how to do
this for midi output?
I thought I saw an email previously in this mailing list regarding
this subject; but I could not find it.
I think I know how to properly display a "p then f" or "p - f"

HI David;
Thank you!
Now what happens when I have multiple repeats with this situation?

Hi David;
I must have misunderstood your suggestion :-(
\midi {
\tempo 4=116
\volta 1 \p
\volta 2 \f
}
I'm using Lilypond 2.22.2, \volta inside \midi {} is not accepted by Lilypond:

Ah yes it is in the postscript area of the source code.

Hi all,
I know this is not difficult but I just can't get it to work.
I want the tempo to look like:
Allegro moderato
die *[image of crotchet] *etwa 108 M.M.
I have this so far:
\tempo \markup \left-column { "Allegro moderato"
\smaller "die etwa 108 M.M." }

If it had been a proposal for LilyPond itself, I would have posted it on
the lilypond-devel list, not lilypond-user.

Have a look at LSR 1138.

I thought you were canvassing user opinions.

Well, Metafont uses a third-order Bézier approximat
Both Postscript and SVG have a built-in arc function capable of drawing an arc (or an
entire circle).
Bézier 2-D curves can approximate a circle, but cannot create a mathematical exact circle
