Re: Png cropping

HI Renato,

As an aside, why would you use backend = eps if you are generating a PNG
file? I think you can omit that.

Png cropping

[Renato Fiorenza]

I read in the documentation that it is possible to create a cropped png by 
using "-dbackend=eps -dresolution=600 —png" and inserting this \paper block:

\paper{
indent=0\mm
line-width=120\mm
oddHeaderMarkup = ##f
evenHeaderMarkup = ##f
oddFooterMarkup = ##f
evenFooterMarkup = ##f
}

However, I think the cropping is too heavy. How can I produce a png with some 
nonzero margins? I've tried to add top-margin, bottom-margin, 
top-system-spacing, last-bottom-spacing, left-margin, right-margin, 
paper-width, but none of them seem to work.

Thanks a lot in advance,
  Renato

Maybe your keyboard is interpreting F8 as something else rather than
the function key proper. On my system and keyboard, F2 is interpreted
as monitor brightness up whether I'm pressing the fn key or not (see
LilyQuick.c line 360). Try uncommenting line 341 of LilyQuick.c. When
you run it, keystrokes will print three numbers in the terminal. If
you press F8 and the third number isn't 66 (see
http://lxr.free-electrons.com/source/include/linux/input.h?v=2.6.38 ),
it's not coming through as F8. A hack would be to modify line 317 to:

myExitCode = xx;

with xx being whatever number F8 produces.

I can't try this out because currently I don't have my MIDI keyboard and
interface available at home. But it looks like a pretty cool thing if I
understand it right that it is essentially independent of the actual
editing environment you're using because it behaves like regular
keyboard input from the editor's perspective.

I hope that installation is actually straightforward enough for people
to actually use the tool and build some base for future development.

Yes, it's independent of the editing environment. It sends keystrokes to
wherever the keyboard focus is.

I've tried to make installation as straightforward as I know how to at this
stage. We'll see how user-friendly it turns out to be in the real world.
But if there is demand, I could try to learn how to make a package.

Re: Markup with dimensions

[Simon Albrecht]

Hi Andrew,
I can’t comment on whether there is a clear point to be made in favour 
of either LilyPond syntax or using the scheme markup macro. Anyway, 
surely you can call with-dimensions from Scheme as well, either from the 
markup macro (which is covered in the Extending Manual, 
) 
 
as #:with-dimensions or directly as make-with-dimensions-markup.

HTH, Simon

Sounds very interesting...

It compiles and build flawlessly on Fedora 25, both with system lua and the
supplied lua.

After adjusting the LQconfig.lua it runs, starts qsynth and I can play and
hear notes from the MIDI keyboard. However, lq doesn't seem to handle
keypresses. Key F8 echoes as ^[[19~ instead of terminating (in combination
with a press of a key on the MIDI keyboard).

So I seem to be missing a setting or parameter.

FWIW: The MIDI keyboard is /dev/midi2, and doesn't have an entry
in /dev/input.

Well, if you require it to work just state it.
But as you should expect for anyone using openLilyLib to have set it up
correctly nothing speaks against simply adding

\include "notation-snippets/shaping-bezier-curves/shapeII.ily"

to your MWE.

\shapeII (just as \shape or any \once \override Slur.control-points) has
to be placed immediately before the start of the slur.

The start of the first slur is the e32, and you've put the \shapeII
immediately before.
The start of the second slur is the , and so you have to put the
\shapeII immediately before that.

I've taken the liberty to make the shape much more obvious but the
following code works:

bass = {
  \clef bass
  \time 1/4
  \tuplet 5/4 {
c'16
\shapeII #'((0 10) (p 20 0.4) (p 20 0.4) (-1 0)) Slur
e32^( g 
\shapeII #'((0 . -10) (p 20 0.4) (p 20 0.4) (-1 0)) Slur
 ) _( g cis'8 )
  } |
}

The overlap of \shapeII and the end of the first slur doesn't matter at
all, as \shape doesn't do more than a \once \override here.

Consecutive slurs and shapeII function

[Andrew Bernard]

Last year I started a thread about how to change the dash pattern in the
case of two adjacent consecutive slurs, successfully solved very simply.
Now the situation arises that I would like to be able to precisely adjust
the slur shape with the \shapeII function in the case of two consecutive
slurs.

The following MWE will only compile if you set it up with openlilylib, and
is meant to be illustrative rather than compilable (sorry - I don't know a
generalised way of including openlilylib in an MWE).

So, how would you get another call to shapeII in here to modify the second
slur shape?

bass = {
  \clef bass
  \time 1/4
  \t 5/4 {
c'16
\shapeII #'((0 0) (p 20 0.4) (p 20 0.4) (-1 0)) Slur

_( g cis'8)

[ANN] LilyQuick 0.9beta - fast accurate Lilypond MIDI note entry for Linux

[Vaughan McAlley]

Greetings,

I’m pleased to announce LilyQuick, a greatly improved descendant of
Finale’s Speedy Note Entry. The basic idea is to play notes on the
MIDI keyboard with your left hand, and use the numeric keypad to enter
the rhythms with your right hand. LilyQuick types the notes for you.
Being able to hear the notes as you enter them is great for accuracy,
and with a little practice you can enter music very quickly, even with
keyboard skills as mediocre as mine.

Installation *should* be as straightforward as installing a couple of
packages with apt-get or equivalent and typing make (see the INSTALL
file), and probably some configuration for your own needs.

https://github.com/palestrina/lily-q

If you like it, let me know if there’s anything you’d like it to be able to do.

Vaughan

README file follows:

%%

LILYQUICK

Welcome to LilyQuick, originally written as a replacement for Speedy
Note Entry when I moved from Finale to Lilypond, and then much
improved. The basic idea is to play notes on a MIDI keyboard with your
left hand, then while they are sounding, press a note on the numeric
keypad with your right hand corresponding to the duration. For
example, to get "f2", play an F on the keyboard, and press number 5 on
the numeric keypad. The advantage to this approach is excellent speed
and accuracy, and you get to hear the notes as they are being entered.

The default key layout is as follows: numeric keypad keys 0-6 produce
notes in conjunction with the MIDI keyboard.
6 - semibreve/whole
5 - minim/half
4 - crochet/quarter
1 - quaver/eighth
2 - semiquaver/sixteenth
3 - demisemiquaver/thirty-second
0 - last note value (useful with repeated dotted notes)

If useLongValues is set to true in LQconfig.lua, the 3 key changes to
\breve. This can be useful when entering early music.

7 adds whole bar rests such as R1* , then changes to data entry mode,
where the numeric keypad behaves as normal. Pressing enter leaves data
entry mode. The type of rest is from the variable fullRest in
LQconfig.lua. So to enter 15 bars of rest, you would type 7, 1, 5,
enter on the numeric keypad.

8 is for entering tuplets. The 8 key enters \tuplet, then enters data
entry mode for the numbers. The enter key leaves data entry mode and
adds the curly bracket " { ", ready for note entry. So for quintuplets
you would press 8, 5, /, 4, enter; which would type " \tuplet 5/4 {"

If you only ever use triplets, you may want to make tuplets into a
simple string such as:
  ["8"] = " \\tuplet 3/2 {",
(in LQkeyboardEvents.lua)

9 just adds a right curly bracket " }"

+ alternates between entering left and right slurs: " (" and " )"

= or / adds a tie "~"

. adds a dot to the rhythm

* changes the previous note enharmonically, for example cis to des.
Press again to cycle between possibilities.

The Enter key either exits data entry mode, or adds a bar check and
newline: " |\n"

F8/F15 exits LilyQuick. Because I don’t know anything about signals,
you need to press a key on your MIDI keyboard to exit properly.

F9/F16 changes the key sharpwards. LilyQuick will play a G to signify
one sharp, up to a C# to signify seven sharps. If you want sharps and
you’re getting flats, try changing the key.

F10/F17 changes the key flatwards

In C major, LilyQuick will type a chromatic scale as follows: c cis d
es e f fis g gis a bes b.

F11/F18 and F12/F19 (and any other numeric key) can be customized at
your pleasure.

IMPLEMENTATION

LilyQuick intercepts keystrokes from the computer keyboard. If they’re
not from the numeric keypad, they are sent straight on to the system.
If they are, they are sent to the Lua program, which can create vitual
keystrokes. At the moment it can send any character that can be typed
on the regular part of the keyboard using the shift key. This includes
all characters I regularly use for inputting Lilypond code. I don’t
know enough about non-English keyboard layouts, and whether people
would want to enter non-ASCII characters when entering notes in
Lilypond. It shouldn’t be too hard to add this feature if the need
arises.

What LilyQuick does with incoming keystrokes is defined in LQkeyboardEvents.lua

Intercepting keystrokes requires superuser privileges (sudo).

CUSTOMIZATION
LQconfig.lua contains a number of options you may wish to change, such
as absolute/relative note entry, MIDI output channel etc. See the
INSTALL file for more information on deviceName and MIDIKeyboardName.
The file LQkeyboardEvents.lua determines how incoming keystrokes are
handled, and is completely customizable. To type a simple string, just
include it (like the entry for "9"). Otherwise the entry should be a
table containing a function, and the parameter to send to it. To send
multiple parameters, put them in a table (like the function
Alternate).

TODO
- Allow make install to put the executable into some /bin directory.
Not sure how to tell it where the Lua scripts are yet.
- Easier time signature changing, either through the 

Problems with parallel voices when using David's accordion push spanner

[Mojca Miklavec]

Hi,

A while ago David Nalesnik wrote some wonderful macros to help me
write a thick line that denote accordion pushing [1]. The macros work
wonderfully in 99% of cases, but there are some strange examples where
this fails.

The example below produces output you can see in the attached PNG. If
I remove "AccordionPushPull", then the scores typeset fine, but I do
need those events.

I tried several other strategies. All I need is a small chunk of code
with different properties (tails pointing in different direction,
perhaps the size or colour of the scores slightly changed to denote
optional part for the player, ...). But whatever I try that works in
normal conditions, fails here.

I'm attaching a "minimal" working example that includes David's code
(which I left untouched).

melody = \fixed c' {
  \time 3/4
  \partial 2
  \startPush d' e' | \stopPush
  << { f'4 e' d' | f'4 d'2 | } \\ { 2.~ | 2. | } >>
}

basses = \fixed c {
  \clef bass
  \partial 2
  f,4  | d,4   | a,4   |
}

\score {
  \new PianoStaff <<
\new Voice = "melody" { \melody }
\new AccordionPushPull \with {
  \override VerticalAxisGroup.nonstaff-nonstaff-spacing.padding = 1
} {
  \melody
}
\new Staff = "staff" <<
  \new Voice = "bass" { \basses }
>>
  >>
}

I would be grateful for a bit of help to fix this.

PS: Other examples of the push/pull macros not really obeying me (but
those are all cases with much lower priority and there's no need to do
anything about those now unless it's related to the problem at hand):

- When push/pull spanner starts at "\repeat volta 2 {}", it's not
properly aligned

- Sometimes I need:
melodyA = {\startPush ... \stopPush}
melodyB = {\startPush ... \stopPush}
melody = {\melodyA \melodyB}
but I need to delete the last \stopPush in A and the first \startPush
in B, else the line is disconnected (placed at different heights).
This is also a problem with \repeat volta 2 {} \alternative { {} {} }
where push events need to cross alternatives even if they are not

accepting.

warning: I think there's a dangling accordion push spanner :-(
but it doesn't tell me the line to help me debug the problem.

 [...] Text events may also
 occur at other times in a track, to be used as lyrics, or descriptions
 of cue points. The text in this event should be printable ASCII
 characters for maximum interchange. However, other characters codes
 using the high-order bit may be used for interchange of files between
 different programs on the same computer which supports an extended
 character set. Programs on a computerwhich   does not support
 non-ASCII characters should ignore those characters.

There must be some convention, but I haven't found an official RP for it.


Personally, I have no idea. Does Lily not do it right?
Best, Simon

P.S. If you can, please don’t top-post, but reply below the quotation 
(as I now did). That makes it far easier to catch up with to what you 
were replying.
