Re: Midiimport für Lilypond/Frescobaldi

[Bernhard Kleine]

Hi Carl,

this has been most helpful and I will organize a keyboard for input. How
to record the tunes and to save them will take some time to learn.

With respect to the other contributions, I have Frescobaldi/Lilypond on
win 7. I have seen that VLC mediaplayer has to be supplied with
softfonts e.g. fluid-softfonts. The installation proposal, however, does
not state how to supply this softfonts to the actual VLC. I have still
efforts before me to get MIDI output on my machine.

Kind regards Bernhard

Denemo will work out of the box to play simple MIDI for you, and it also
has a Playback View which will play LilyPond's MIDI output for you
(which is more sophisticated). Again, this will work out-of-the-box on
windows.

VLC 32bit 2.0.8 is the last windows version to have
- preferences>input>audiocodecs>fluidsynth

I have win7 64bit and installed the 64bit VLC for normal use.

Occasionally I produce singalong mp3 files from LilyPond midi.
I do this via the 32bit VLC which is installed 'in parallel'.
Maybe a bit dodgy - and so not for regular use?

Thanks a lot - sometimes it's so easy... :-)

As for Thomas Morley's suggestion (setting penalties), this "sort of"
works, but for me it created fewer line breaks, resulting in a
not-so-pretty sqeezed layout.

This is not a problem in my case - there are plenty of "allowed" line
breaks, and as long as every page break occurs only at an allowed line
break (this sounds quite tautological to me), everything is fine.

Which is the problem.  If only 30% of your allowed line breaks are also
permissable for a page break, the likelihood that any particular line
break is "wrong" for a page break is 70%.

You can actually _also_ work with penalties in order to give more
preference to making line breaks at page-break-friendly position.

But LilyPond will still first create one long strip of paper without
considering page boundaries, and will only then look at where it has
made page-break-friendly line breaks for cutting this strip into pages.

> and as long as every page break occurs only at an allowed line break

Allowed for a line break and allowed for a page break are two different
kinds of thing.

Well, in this case David N's solution is better since it uses the normal
(skyline-based) page positioning rather than treating everything as
markup lines.

Mine is easier to understand, and the \center-in-line or something more
general (align-in-line?) is really annoyingly absent in the LilyPond
markup toolbox.

So there is certainly _something_ from my proposed solution that should
really be readily available in LilyPond, and it's likely not too hard to
abstract something useful for any kind of markup here.

David N's solution is the better one but it is trickier to identify a
tangible component to abstract into a generally useful utility.

Now…   ;)

Perhaps there’s a way your new-found [?] knowledge/skill in this area can help 
with a long-time feature request I’ve had: an \offset-like way to nudge systems 
— especially the explicit Y-offset property, but also the alignment-distances 
if possible. Avoiding trial-and-error there would be a huge savings.

Bernhard,
midi2ly.py for converting .midi files to Lilypond is operational in the current 
version 2.19, but it has some limitations. You might want to have a look at it.
I've been working on updating it, but it's been slow going (for me).  If you do 
try it, let me know of any specific concerns.

1. I hadn’t seen his solution. I agree, it’s wonderful.

2. Perhaps I should have said “especially when David * is on the case”.  =)

3. Regardless, your solution was ingenious and helpful, as always.

If I understand it correctly,

  \center-in-line “foo” = \fill-line { “” “foo” “” }

If so, I agree this would be a wonderful addition to the toolbox.

> David N's solution is the better one but it is trickier to identify a

I’m hoping (see my other email) that there might be a way to turn his solution 
into an \offset-like function for explict system positioning. That would be 
useful (though perhaps not as *generally* useful as something like 
\align-in-line).

Thanks,
Kieren.

Yup.  More importantly,

\center-in-line { foo bar }
= { \fill-line { "" foo "" } \fill-line { "" bar "" } }

and that's something where straightforward \fill-line cannot be readily
employed, contorted or not: centering a whole markup list in a line
width box.

Even though I think that just \fill-line { foo } does centering,
splitting a markup list into separate markup lists with just a single
element each and processing each of those markup lists with a markup
command is not something available out of the box.

Well, the horizontal is a much different beast than the vertical.
Horizontal is easy in LilyPond, vertical not at all so.

Directly contradicting what I just wrote, there is an issue with
vertical positioning in my little experiment.  Try this:

\version "2.19.59"

\paper {
  ragged-right = ##t
  indent = 0
}

\layout {
  \context {
\Score
\override NonMusicalPaperColumn.after-line-breaking =
#(lambda (grob)
   (if (eqv? (ly:item-break-dir grob) 1) ; line beginning
   (let* ((sys (ly:grob-system grob))
  (sys-width (ly:grob-extent sys sys X))
  (layout (ly:grob-layout grob))
  (line-full-width (ly:output-def-lookup layout 'line-width)))
 (ly:grob-set-nested-property! grob
'(line-break-system-details X-offset)
   (/ (- line-full-width (interval-length sys-width)) 2)
  }
}

music = {
  \repeat unfold 500 { c,4 }
}

\score { \music }

%%

Notice that with the override, systems are placed lower on the page
and the bottom margin is lost.

The problem occurs with the call to ly:grob-extent.  In my experience,
calling this function for the X-axis doesn't result in (visible) side
effects, but here they are.

Hi David,

It’s not *quite* that simple, I think…

Using

\paper {
 ragged-right = ##t
 indent = 0
 system-system-spacing.padding = 2
 bottom-margin = 1\in
}

we see that most of the margin is kept, but there are still system-system 
collisions (cf. m 120). So systems are placed lower, yes, but with some 
awareness.

Maybe if you save the original Y-position, and then explicitly “reset” it 
afterwards, it will eliminate this problem? Still doesn’t explain what’s 
actually going on — which would be nice to know — but might fix this function.

Kieren.

relative offset of systems [WAS: Center-align a score]

A little experiment leaves me hopeful.

(So far) it looks like it's a relatively simple matter to add another
line-break-system-detail: "extra-Y-offset" which will move a system
from its calculated position (whether left to the default, or
positioned with 'Y-offset).

Just like an explicit setting of Y-offset, it will act without regard
to vertical collisions.

To try this out, you will (unfortunately) either need to (1) apply the
attached patch or (2) make changes to your scm/page.scm by hand.  (I'd
suggest commenting out the original make-page-stencil with #!  [...]
!# and adding a copy with the changes, so it's easy to revert if need
be.)

I'll just quote the relevant changes with some context.

Within the function make-page-stencil:

[...]

 (add-to-page (lambda (stencil x y extra-y)
(set! page-stencil
  (ly:stencil-add page-stencil
(ly:stencil-translate stencil
  (cons
   (+
system-xoffset x)
   (-
0 y extra-y (prop 'top-margin))) ; NB

  )
 (add-system
  (lambda (system)
(let* ((stencil (paper-system-stencil system))
   (y (ly:prob-property system 'Y-offset 0))
   (extra-y (ly:prob-property system 'extra-Y-offset 0)) ; NB
   (is-title (paper-system-title?
  system)))
  (add-to-page stencil
(ly:prob-property system 'X-offset 0.0)
y
extra-y) ; NB

[...]

%%

Try it out with this:

%%
top = \repeat unfold 5 { c''4 d'' e'' f'' }

bottom = {
  \clef bass
  \repeat unfold 5 { c,1 }
  \break
}

\new PianoStaff <<
  \new Staff {
\top
\top
\top
  }
  \new Staff {
\bottom
\overrideProperty
Score.NonMusicalPaperColumn.line-break-system-details
#'((extra-Y-offset . -2))
\bottom
\overrideProperty
Score.NonMusicalPaperColumn.line-break-system-details
#'((extra-Y-offset . 12))
\bottom
  }
>>
%%%

Sorry for the awkwardness, but I hope this is useful to you!

It will fail if system-separator-markup is used.

Here my attempt (for comparison I added greyed stencils)

 (add-system
  (lambda (system)
(let* ((stencil (paper-system-stencil system))
   (y (ly:prob-property system 'Y-offset 0))
   (extra-y (ly:prob-property system 'extra-Y-offset 0)) ;; NB
   (is-title (paper-system-title?
  system)))

 For comparison: print the greyed system-stencil without extra-y
  (add-to-page (stencil-with-color stencil '(0.8 0.8 0.8))
(ly:prob-property system 'X-offset 0.0)
y)
 The moved system-stencil
  (add-to-page stencil
(ly:prob-property system 'X-offset 0.0)

(if (and (ly:stencil? system-separator-stencil)
 last-system
 (not (paper-system-title? system))
 (not (paper-system-title? last-system)))
(begin
 For comparison: print the greyed system-separator-stencil without 'extra-y

   (average (- last-y
   (car (paper-system-staff-extents last-system)))
(- y
   (cdr (paper-system-staff-extents system)

 The moved system-separator-stencil
  (add-to-page
   system-separator-stencil
   0

   (+
 (average (- last-y
 (car (paper-system-staff-extents last-system)))
  (- y

 (/ extra-y 2)  ;; NB
(set! last-system system)

Good point.  Actually, I already incorporated this suggestion in a
patch I'm currently testing.  (Middle of make doc.)  I decided to use
an "extra-offset" property which allows for displacements along both
axes.

Thanks so much for pointing this out.  I didn't notice that the
variable "y" was used elsewhere.  As soon as the patch testing has run
its course, I'll add this in.

Wish I could use the greyed background in the regtest, but that's not possible.

Best,
David

Fixed.  Added system-separators to the regtest.

\magnifyMusic omits unison notes from \partcombine?

[Karlin High]

A songwriter looked at my LilyPond job and asked, "Can you make the note
heads bigger in proportion to everything else?" Yes, thanks to
\magnifyMusic, I thought. It's a SATB hymn, I'm using \partcombine, and
apparently \magnifyMusic doesn't pick up the unison notes the way I'm
writing it. Minimal example below, PNG result attached. Magnify is at 1.2
for effect; I'm using 1.1 in practice.

% BEGIN LILYPOND CODE
\version "2.19.59"
one = { a'2 f' }
two = { f'2 f' }
\partcombine #'(2 . 9) \magnifyMusic 1.2 { \one } \magnifyMusic 1.2 { \two }
% END LILYPOND CODE

I've found I need to put \magnifyMusic inside \partcombine, because it seems
to have no effect the other way around. Any ideas for how I could get
\magnifyMusic to catch the unison notes? Or a different way of achieving the
same thing?

\score {
  \partcombine \one \two
  \layout {
\context {
  \Score
  \override NoteHead.font-size = #3
}
  }
}

Hope that helps!
