Re: midi2ly

(Remember to reply-all, or put the LilyPond user group in the CC:)

I think the easiest thing to do at this point is to rename midi2ly ->
midi2ly.py.  Windows may ask you how to execute py files, then choose
Python.  Now try:

misi2ly.py --version

Re: midi2ly

[Knute Snortum]

I'm wondering if this could be a PATH issue. Can you type

lilypond --version

and get a meaningful response? If not, you may have to put the LilyPond bin
directory on your PATH. Or use the full pathname midi2ly.

Re: midi2ly

Hi, thank you. I tried that, and no, that also comes up as 'not recognized.' 

I don't see a separate installer for midi2ly, so how can I install it?

You can try:

   midi2ly --version

to see if midi2ly has been installed correctly.  If it is, possibly
midi2ly cannot handle your midi file.

Hi again David,

I didn't understand what you wrote, but I did a bunch of things to make it
work. I think this will solve the convert-ly problem as well, though I
haven't checked. This is in mintty shell using Cygwin on Windows 10.

$ ls -l  /cygdrive/d/Program\ Files\ \(x86\)/LilyPond/usr/bin/midi2ly

[Please keep the discussion on-list where others might see it,
particularly Windows-users.]

Have you tried just invoking python3 itself, placing the name of the
script next, and then whatever arguments you were using, ie:

$ path-to-midi2ly arguments …

  ↓

$ python3 path-to-midi2ly arguments …

This is effectively all that a shebang does: you can execute a script
by name without having to care about which interpreter it needs.
(You may need path-to-python3 as well.)

David.

Two possibilities strike me, not being a Windows user:

1) The first line of midi2ly is a shebang, ie
   #!/usr/bin/python3
   which is the recommended way to run Python 3 scripts.

Even where "python" alone now invokes python3 rather than
python2, python3 should still be defined.

2) The third line of midi2ly gives the script's name as
   # midi2ly.py -- LilyPond midi import script

The .py suffix should allow OSes like Windows to invoke
the appropriate interpreter. For help with this, perhaps
look at this post and this thread (both for convert-ly):

https://lists.gnu.org/archive/html/lilypond-user/2021-01/msg00140.html
https://lists.gnu.org/archive/html/lilypond-user/2021-05/msg00301.html

Cheers,
David.

Re: Restrict midi2ly to one voice (partly off-topic)

[Stephan Schöll]

Thanks for your reply, Hans.

I can confirm that the source was a single (Cubase) part and all notes
were on the same MIDI channel.

I checked the source data of the MIDI file (in Cubase) again and in
fact: I found a few places where two or more simultaneous notes did not
have the same length which I had overseen in earlier. My fault, sorry ;-)

With several round-trips Cubase-midi2ly-Lilypond/Frescobaldi I was able
to locate all these unfavourable constellations.

What I have learned: As soon as midi2ly meets more than one (overlapping
note with divergent start/end midi2ly interprets it as polyphonic music,
 thus creates additional voices and fills the score up to this
"polyphonic" position with rests in the additional voice/s.

Stephan

Re: Restrict midi2ly to one voice

[Hans Aikema]

"midi2ly converts tracks into Staff and channels into Voice contexts"

so make your midi-file contain all music on a single channel should result in a 
single voice

apparently, given the results, your midi is currently 4 channels with music

Hans

Restrict midi2ly to one voice

[Stephan Schöll]

Hi

I have a self-recorded/-created midi file which I have quantized and
simplified to death (lengths and durations to 1/16, no overlaps). Let's
assume it's the the left hand part of a piano score. Now I want to
convert it to a lilypond file using

midi2ly.py -d 16 -s 16 -o "\MITM_Piano_LH.ly" "\MITM_Piano_LH.mid"

This works without errors on the command line. But lilypond generates 4
voices and distributes the notes all over these voices which is a mess.
I optimized the midi file in a way that midi2ly might simply produce one
voice.

How can I tell midi2ly to create only one voice? I couldn't find any
helping hint in the documentation
https://lilypond.org/doc/v2.18/Documentation/usage/invoking-midi2ly.en.html.

Best Regards
Stephan

What's odd to me is that all the midi2ly programs I have
are lacking the .py extension. They also object to being
fed a -n option. (Also, the program wouldn't normally be
found in the same directory as users' data files.)

I agree about the height when viewed in a wide window.  There are a couple
of ways you can control it.

   1. The text area is resizable. You should be able to drag it from the
   lower right corner to whatever feels comfortable.
   2. The font sizes are all specified in viewport width units so mobile
   users will have at least a fighting chance to read it.  On a desktop, if
   you shrink the width of your browser window the fonts and the rest of the
   layout will shrink to expose more of the vertical page.

The reason for the tall text area is to support users who want to enter
extended music samples.

That's worth considering.  Thanks!

I've just added a couple of new examples you can paste and try. One is a
few bars of a two part duet voiced for flute and guitar. The other is a
little percussion pattern for bass drum,  snare and ride cymbal.

Cheers,
Mike

Seriously, I decided to focus on midi output because it's the only thing
that almost all the other music software will import, more or less.

Thanks for the interest and feedback and sorry to take a couple of days to
respond.  I'll plead New Years celebrations (and also adding GM instrument
support to tbon.)

Hmmm, I don't see a 2.21 binary for OS X.  I downloaded 2.19.80.  Got
bogged down trying to run mid2ly as a standalone under python 3.5.

Thanks for testing it, David.  What options did you use for midi2ly and
lilypond?  My command lines were:

./midi2ly.py -o meter.ly -n -V 1 meter.midi
lilypond meter.ly

I only got one bar check complaint when LP processed meter.ly which
contains:

TrackA = {
  \numericTimeSignature\time 4/4  c'4 d'4 e'4 f'4  |  % orig
  \numericTimeSignature\time 2/4  g'8 a'8 g'8 g'8 a'8 g'8 c''4  |  % orig
  \numericTimeSignature\time 6/8  c''4 g'8 a'8 g'8 g'8 a'8 g'8  |  % orig
  \numericTimeSignature\time 2/4  c''4 c''4 r2  |  % orig
}

It was on the 6/8 line in the above which contains 8 eighth-notes.

I'll try upgrading to 2.21 and see if that makes any difference.

The midi file matches your msc2-meter-example.png, I can show you

Nice idea to have c--c mean c8. c16 which is much more error prone to 
type.

You could probably change your python program to output lilypond code
directly.

And here with 2.19.16.

The bar checks fails because midi2ly puts in barchecks in the wrong 
places, don't know why.

Is anyone maintaining midi2ly?

[Michael Ellis]

Hi, It's been a few years since my last post here.  I'm wondering about the
status of midi2ly.  I just tried the version that came with 2.18.2 and it
seems to handle meter changes incorrectly.  Here's a short example produced
from a midi file imported into MuseScore 2.1

[image: msc2-meter-example.png]

and here's the result of processing what midi2ly produced from the same file

[image: ly-meter-example.png]

The MuseScore output is correct and matches the tempo and meter items
embedded in the original midi file (attached).  I've also verified with 2
different DAW's (Reaper and Logic X) that the midi file is imported
correctly.

The application that produced the midi file is called *tbon*. It's a
shorthand notation language I wrote for projects where fast notation entry
is more important than having the full capabilities of LilyPond.  If you're
curious about tbon, go to https://github.com/Michael-F-Ellis/tbon . The
README has a link to a live online demo.

I'd really rather use LP than MuseScore for the times when I want to
engrave the output from tbon since LP still produces better looking scores,
imo, but not being able to handle meter changes is a showstopper.

Thanks,
Mike

Hi Ming

I never use midi2ly, but I've just tested it in Frescobaldi using a 
MIDI generated by lilypond.

Everything works fine.
You should see a new file starting with something like this:

% Lily was here -- automatically converted by /usr/bin/midi2ly from 
/tmp/23-10-63.midi


You use Windows, right?
I don't think that it's a path problem. If lilypond runs in 
frescobaldi, also midi2ly should be able to run.
If midi2ly fails for some reason and Frescobaldi doesn't warn about 
this, then I'd say this is also a bug of Frescobaldi.


But I guess that the source of your problem is in midi2ly.
Please try debugging it using a command line:

midi2ly file.ly

and paste the output here

Keep me in Cc, as I'm going in holidays soon and I've disabled all the

After wasting some time writing a new package for python-ly (just to
realize that the package already existed), translation of pitches
works wonderfully out of the box:

ly-3.5 "translate deutsch" -o new.ly old.ly

So even if Frescobaldi is broken for me at the moment, at least the
command-line tool does the job.

Parsing and doing my own acrobatics by adding buttons will take a bit
longer until I'm able to go into the depths of the documentation.

Thank you,

It's actually the same advice, as Frescobaldi uses python-ly to perform

originally an internal module of Frescobaldi then it was moved out, as 
it can be useful as an independent tool).

Asking midi2ly to output pitch names in another language

[Mojca Miklavec]

Hi,

Is it possible to convince midi2ly to output pitch names in, say
\language "deutsch"
?

I prefer using "b" to "bes".


Also, is it possible to get the output in something like
\fixed c'
?

Those problems are not something that I couldn't solve by either
manually editing the scores or writing a simple script to do it for me
or by transposing the melody one octave lower and run the scores
through another cycle of lilypond->midi->lilypond cycle. It's just a
convenience.

Thank you,

Re: midi2ly dll error

[Gianmaria Lari]

Ciao Martin,

- Which Lilypond version did you installed?
- If you installed Frescobaldi could you test if the "import midi" feature
works? To test it:  File/Import/Import midi and then specify a simple midi
file. In my tests it should not work IF you have Lilypond version 2.19.39
and 2.19.36 (didn't test with other version) AND you have Python 2.7 in the
path.


if you can, could you please check the folder

Maybe it's a bug of the Lilypond installer? In my case (I carefully tested
it twice) Lilypond installer installed bundled python compiler even if I
unchecked it.

That's strange indeed: it's there, but (as far as I know) it isn't used. 
On the commandline "python --version" gives me 2.7


To be sure I could delete or rename the file and reinstall LilyPond, to be

check the bundled-python option.

It looks like a python problem.
Thus, I'm not sure I can help here, I've neither windows nor do I know python.

Some observations, though:
On my Linux-machine I've Python 2.7.9, but "2.19.36" ships Python 2.4.5

If I try to invoke midi2ly with system-python I get
Traceback (most recent call last):
  File "midi2ly", line 54, in 
import midi
ImportError: /home/hermann/lilydevel/usr/lib/lilypond/current/python/midi.so:
undefined symbol: Py_InitModule4

Using lilypond's python all works.

HTH a bit,
  Harm

Ciao Thomas,

I tried to run directly from the shell but I got same error:

C:\Program Files (x86)\LilyPond\usr\bin>midi2ly.py

Traceback (most recent call last):

import midi
ImportError: No module named midi

I'm using lilypond 2.19.35.

Hello David,

Thanks for pointing this out.

I don’t use bash often in fact, since my default shell is tcsh.

And it turns out I have a lot of bash left-overs from the machines I was in 
charge professionally some time ago…

Starting at step 5 (called 1 in your quote above), when your bash
shell starts up as a login shell, it reads your ~/.profile file for
your personal initialisation.

(But only a login shell, so that these commands are not repeated every
time a subsequent shell starts.)

Users who write scripts and/or programs that they want to invoke just
by typing their name will typically place these scripts (or links to
them) in one directory conventionallly called ~/bin and step 1 of the
instructions shows you how to make that if it isn't already there.

(You can run scripts/programs from anywhere by giving a pathname,
ie something containing a /, but they must be in your $PATH if you
just want to be able to type a bare name without a slash.)

Steps 2 and 3 show how you can write scripts that you will execute
by typing their (short) name, which will in turn execute a program
that has a very long name. "$@" will pass on to that program any
options and arguments you give.

For you to be able to invoke a program in this way, your script must
be executable, and that's step 4. (You need to do it to each script.)
You will then be able to type, eg, midi2ly -h   or midi2ly --version
and bash will run that script, see that it starts with #!/bin/bash
and start a bash subshell which will execute the exec command on the
appropriate program.

So the final link in the chain is to put your ~/bin into your $PATH.
~/.profile does this with   export PATH=$PATH:~/bin

When this is executed in your ~/.profile, the righthandside is
expanded by the shell into

the-whole:of-the:preexisting:value-of-$PATH-in:a-list:~/bin

where you'll see lots of directories separated by : (colons) with
yours tacked onto the end. This string then becomes the new value of
$PATH. "export" is necessary to make bash pass it to all subsequent
commands and subshells.

>Also, can anyone give me an example of what to type in the terminal to
>convert a midi file to lilypond format? 

midi2ly name-of-midi-file.midi

On my system, it creates (or will overwrite without warning) a file in
the current directory called   name-of-midi-file-midi.ly   unless I
specify -o newfilename.

David.

Re: OT help with midi2ly on command line mac os blind user

[Jacques Menu Muzhic]

Hello Daniel,

The contents of variable PATH (i.e. $PATH) is a sequence of directories names 
separated by colons :

bash-3.2$ echo $PATH
/Library/Frameworks/Python.framework/Versions/3.2/bin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/texbin:/usr/local/llvm-3.0/clang+llvm-3.0-x86_64-apple-darwin11/bin:/usr/local/llvm-2.9/bin:/opt/local/bin:/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands:/usr/local/bin:/usr/local/LocalLaTeX:/usr/local/erlang/bin:/usr/local/nagios/bin:/usr/local/nagios/libexec:/usr/local/rsync/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/TeX/texbin:/Users/menu/bin:/usr/X11R6/bin:/opt/gnome/bin:/usr/X11R6/bin:/usr/local/scripts:/condor/release/bin:/condor/release/sbin:1.4.4/bin:/usr/local/latex2html-2008/bin:/usr/bin:/usr/sbin:/Developer/Tools:/usr/libexec:/usr/local/openssl/bin:/usr/X11R6/bin:/usr/local/cvs/bin:/usr/texbin:/opt/local/bin:/usr/local/mysql/bin:/Users/menu/yagarto/yagarto-4.6.0/bin:/Applications/LilyPond.app/Contents/Resources/bin:/Developer/usr/libexec:/Developer/usr/llvm-gcc-4.2/bin:/Users/menu/bin

When you submit a command to bash, it looks first among its built-in commands 
and then in $PATH, in the order  of the directories, to find how to 
execute it.

You can ask bash which command will be executed if you type a command:

bash-3.2$ type pwd
pwd is a shell builtin

bash-3.2$ type bash
bash is /bin/bash

bash-3.2$ type foo
bash: type: foo: not found

This command add directory bin in your home directory (~) at the end of the 
PATH:

export PATH=$PATH:~/bin

bash-3.2$ type midi2ly
midi2ly is /Applications/LilyPond.app/Contents/Resources/bin/midi2ly

ash-3.2$ midi2ly -h
Traceback (most recent call last):
  File "/Applications/LilyPond.app/Contents/Resources/bin/midi2ly", line 54, in 

import midi
ImportError: 
dlopen(/Applications/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so,
 2): no suitable image found.  Did find:

/Applications/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so:
 mach-o, but wrong architecture

This shows that Python module midi.so is not usable on my machine. I run OS X 
10.11.3:

bash-3.2$ uname -a
Darwin macbookprojm 15.3.0 Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58

Can’t help you more there unfortunately, I’ve got no experience in handling 
MIDI files beyond playing them for scores control.

OT help with midi2ly on command line mac os blind user

[Daniel Contreras]

Hello all, 
I am trying to wrap my head around this whole command line terminal. I am 
attempting to follow the steps that are listed on the “Mac OS” section on the 
lilypond website. I ,think, I have followed each step correctly through step 4, 
which is to make the file executable. I am confused as to what step 5 is 
talking about. It is the following: 
Now, add this directory to your path. Modify (or create) a file called .profile 
in your home directory such that it contains
export PATH=$PATH:~/bin
This file should end with a blank line. 

I guess my questions are the following: 
How will these steps help me in using midi2ly?
Also, can anyone give me an example of what to type in the terminal to convert 
a midi file to lilypond format? 

Thanks for any answers and/or suggestions. I apologize for the long off-topic 
email. Daniel, 
Also, ha I don’t know why my computer is putting 1’s at the beginning of each 
line.

Please:

1. Where is the manual? The man page says it is a texinfo document, but

2. Trying to convert a  Midi  file, nearly all notes have weird durations.
I
assume that I should add a  -d  or  -s  but the manpage gives no hint of
the units of  duratioon .

3. Lyrics get mangled. To see this, go to

Right. There are several problems: midi2ly compiled 32-bit for an old Python 
API. I reported how to fix that, so perhaps it has beed done in latest LilyPond.

When I exclude /usr/bin/python, thus using LilyPonds’s own Python, I get
  Fatal Python error: PyThreadState_Get: no current thread
which is a new problem.

To be more precise, it seems to be a problem with the file 
/Applications/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so,
which, as python reports, is mach-o but wrong architecture.

Patricks-MacBook-Pro:~ pat$ file 
/Applications/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so
/Applications/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so:
 Mach-O bundle i386
Patricks-MacBook-Pro:~ pat$ machine
i486

So perhaps i need a midi.so which is for i486 architecture, not i386 
architecture?  (I’ve left my safety zone now.)

Thanks, but unfortunately I still have the problem with that:

It seems like a python problem.

It works with a script, named say “midi2ly” and put in the PATH, with the 
single line:
exec /usr/bin/python /Applications/LilyPond.app/Contents/Resources/bin/midi2ly

architecture problem with midi2ly on a mac

[Cynthia Karl]

When I do:  midi2ly —help

I get:
Patricks-MacBook-Pro:mi2ly.0.12 pat$ midi2ly --help
Traceback (most recent call last):
  File "/Applications/LilyPond.app/Contents/Resources/bin/midi2ly", line 54, in

This is on a MacBook Pro running OS X 10.10.2.

uname -a gives:

Darwin Patricks-MacBook-Pro 14.1.0 Darwin Kernel Version 14.1.0: Mon Dec 22

I’m pretty sure that means 64-bit mode.

Is there any way I can get midi2ly running on this computer?___

One can recompile the file python_midi.c that is in the LilyPond GIT repository:
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=blob;f=python/midi.c;h=890798c66a4f022139013c81e641b743756aef15;hb=HEAD


For i386:
clang -dynamiclib -I/usr/include/python2.7/ python_midi.c -arch i386 
-lpython2.7 -o midi.so

For x86_64:
clang -dynamiclib -I/usr/include/python2.7/ python_midi.c -lpython2.7 -o midi.so


The script then seems to work if one writes:

For i386:
exec /usr/bin/arch -i386 /usr/bin/python2.7 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@“

or 

exec /usr/bin/arch -i386 /usr/bin/python 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@“


For x86_64:
exec /usr/bin/python2.7 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@“

or

exec /usr/bin/python /Applications/LilyPond.app/Contents/Resources/bin/midi2ly 
"$@"


If the part ‘/usr/bin/python’ is excluded, it fails on my system, because it 
then tries MacPorts '/opt/local/bin/python’.

If you don’t like that pesky warning, you can always try. But the MIDI file I 
used it on seemed to work with Python 2.7.

So- as I understand it right- I can install python 2.4 into /opt/local/bin via 
macports

and then change the line to

exec /usr/bin/arch -i386 /opt/local/bin/python2.4 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"

Would that work?

The LilyPond midi2ly file has been compiled for the API in Python 2.4, so the 
line should really be: 
exec /usr/bin/arch -i386 /usr/bin/python2.4 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@“

But this version does not come with the system installation in /usr/bin/ of 
later OS X.

Strictly speaking, it is a warning as it passes the compile, not an error which 
would abort. So it is a relevant issue, though it seems to work.

I make a script - an executable, which should be in the PATH (see below).

There are several ways to make a script:

One way is first making the text file in Terminal by
    touch midi2ly
If you want use a text editor like Xcode, go to Terminal and write
  open -a Xcode midi2ly
and paste in the line
  exec /usr/bin/arch -i386 /usr/bin/python2.7 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"
 and save.

Alternatively, make the file directly by writing
  cat > mid2ly
Paste in the same line as above followed by D to end ‘cat’.

The set the executable permissions by
  chmod a+x midi2ly
Check that it is right with
  ls -l midi2ly

Then put in somewhere in the PATH. In later OS X, /usr/local/bin/ is in the 
searchpath, but putting it there requires ‘sudo’ permissions (unless changed as 
some running homebrew do). But to do that write
  sudo cp midi2ly /usr/local/bin/
By using ‘cp’ rather than ‘mv’, the other file metadata becomes right.

Otherwise, you might make a directory ~/bin/, make sure it is in the PATH by 
changing .profile. Then ‘sudo’ isn’t needed.

I wrote a script ‘midi2ly', which should be put in the $PATH, containing the 
single line:
exec /usr/bin/arch -i386 /usr/bin/python2.7 
/Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"

The suggested workaround indeed does not work on any system I tried.
I updated the issue with details and a functioning workaround.
Of course the solution would be to build the library midi.so as a
universal binary containing both 32 bit and 64 bit code.

Hello Ole,

I get that too on Mac OS X 10.9.4:

 > file midi.so 
midi.so: Mach-O bundle i386


So LP 18.2 provides only a 32bit (i386) version of midi.so, and our recent 
versions of OS X are 64 bits:

It's easy to say "good luck with that", but there is an underlying
lesson in there: it's probably not easily doable to cast the rules of
good engraving into actual code with either Finale, Sibelius, _or_
LilyPond.  With Sibelius, their corporate parent apparently decided to
stop investing any more manpower in the improvement of typesetting and
gave the core developers the boot.  With Finale, one has the impression
that they have not made quality of typesetting a high priority anyway.

With LilyPond, we are working with volunteers and enthusiasts, and they
will often put in more work than one could justify to management for a
given result.  We are reaching the point of diminuishing and
self-defeating returns often already: improvements are hard to do, and
get in the way of doing further improvements.

So what is called for is an architecture that makes it rather
straightforward to specify good rules of typesetting rather than
spelling out code that conflicts with other code in ways that are an
artifact of the coding rather than based on a specification.

Starting from scratch, of course, provides a chance to design an
architecture suitable for the full requirements one is familiar with
rather than evolve an architecture while the requirements become more
and more apparent.

Or putting it more concisely: stealing good ideas requires good code.
You don't use rickshaws for a copper heist.

Re: midi2ly doesn't follow time signatures (beat divisions)

[Shane Brandes]

O.k.

 I ran it the 2.18 to midi through midi2ly does in fact fail miserably
in appearance of typeset result however if you inspect the durations
they are correct. However the odd thing is midi2ly makes a 2.14 type
file. So it for whatever reason seems to be producing durations in the
form of x8*y where x is the note a-h and y is the multiplier. so a
half note would be x8*4. So it looks as though this could be improved
by someone competent in the whole programming realm.

If I do

something strange happens. The first note of the tune should be e'''16 but 
"16" is missing:


An excerpt from the resulting testmidi-midi.ly:

trackBchannelA = \relative c {

I am quite sure the midi file is OK. It is read and converted perfectly by 
other programs like musescore and mtm (=mup to midi). If I change e''' to 
e'''16 manually, everything is fine.

Sadly, we don't have any midi2ly guru anymore, and the midi2ly script
is barely maintained at all.


If you have a precise feature request in mind, you may send it to our

RE: How do I Invoke midi2ly in windows?

[philippe sicabaig]

Probably there was some problem with my midi file. I created a 
  very simple midi file especially to test and it worked.
Still the ly file 
  created is quite unusuable, (old ly version, I had to convert it...). As a 
  result I wasnt able to export a pdf so easily.
Is there an update of 
  the  midi2ly.py file I have? I am doing piano sheet music on windows 7, 
  so do you know if there is a good program or way to create a midifile 
  compatible with midi2ly.
I would like for example to play the song, 
  quantize it, then separate on to channels the right and the left hand so that 
  lylipond is able to distinguish them.
If you have some tips and advices, I 
  would be glad to hear them, otherwise, have a good day 
  anyway!

Hello everybody,

I 've tried to use the midi2ly function in windows to convert a midi 1 
file into

a ly file.

I typed in the command line something like:

midi2ly.py --allow-tuplet=8*2/3 C:\Documents\test.mid

Actually I tried many ways to invoke this command. But in the end, the 
command

line always answers something like that:

Traceback (most recent call last):

SystemError:

I am not getting any ly file anywhere.

I searched on the internet how to do, but I can't figure it out and I am
stucked. I noticed that many people had problems to understand how to use 
this

Using the syntax you have provided works perfectly for me on a Windows Vista

How do I Invoke midi2ly in windows?

[Philippe]

Hello everybody,

I 've tried to use the midi2ly function in windows to convert a midi 1 file into
a ly file.

I typed in the command line something like:

midi2ly.py --allow-tuplet=8*2/3 C:\Documents\test.mid

Actually I tried many ways to invoke this command. But in the end, the command
line always answers something like that:

Traceback (most recent call last):
  File "C:\Program Files (x86)\LilyPond\usr\bin\midi2ly.py", line 991, in ?
main()
  File "C:\Program Files (x86)\LilyPond\usr\bin\midi2ly.py", line 989, in main
convert_midi (f, o)
  File "C:\Program Files (x86)\LilyPond\usr\bin\midi2ly.py", line 810, in conver
t_midi
for (dur, num, den) in global_options.allowed_tuplets:
SystemError: /main/src/gub/target/mingw/src/python-2.4.5/Objects/listobject.c:25
5: bad argument to internal function

I am not getting any ly file anywhere.

I searched on the internet how to do, but I can't figure it out and I am
stucked. I noticed that many people had problems to understand how to use this
function.

It would be great if some people who know how to invoke midi2ly and reach to use
it could tell what they exactly type into the command line to have a positive
result.
Could you please do that?

Philippe

are you sure you're using the correct version?

problems with midi2ly often occur when

 - the filename contains blanks
 - the directory contains blanks

best is to make sure you run midi2ly from the directory where the file is.
(use CD … to go there) 
if the filename contains blanks, include it in quadruple double-quotes
("""")

Re: Midi2ly Error

[Graham Percival]

Yes, and that's why I asked you to create tiny midi files with the
different programs, and to upload them to that particular bug
report.

If the files only contain one note, it'll be easier to examine
them for differences (if necessary, byte-by-byte).

The info about different midi programs is interesting, though, and

I'm encountering problems with midi2ly. I receive the error below when

That should definitely not be necessary! Just typing
midi2ly whateverfilename.midi
should do the same thing.

If you want to investigate, open a command prompt, type
set path
and copy the resulting output into an email to the mailing list.

In the email from Eluze, it's explained what you should look for in this 
output if you want to investigate it yourself.

And if you have a midi editing program then you should be able to 
quantize everything to 100% note duration before converting it thus 
making a much better looking ly file without fraction lengths.

RE: Midi2ly work for Windows?

[Austin W]

So I got it to work after realizing that midi2ly.py is just a big text file. 
You have to type python before midi2ly to load midi2ly in python. Is this in a 
help file somewhere? So it's:

c:\Program Files\Lilypond\usr\bin\python midi2ly.py type1midi.mid

And if you have a midi editing program then you should be able to quantize 
everything to 100% note duration before converting it thus making a much better 
looking ly file without fraction lengths.

there are 2 things to specify:

- the path in which the system has to look for midi2ly.py, typically
c:\Program Files\LilyPond\usr\bin\
you can check this with "set path" in the command shell.

- a program that is supposed to run programs with a specific extension -
here it is ".py"; check this with "set pathext" as above
if .py is not included in this variable, you can add it in the "standard
program definitions" (or similar)

[note that the command "set path" will display both these variables]
  


As has already been said, this should work out of the box if you use the 
LilyPond installation package.

One additional remark:
Even if these problems are solved, and you are finally able to run 
midi2ly, don't expect too much of the results. At this moment midi2ly does 
a pretty bad job in converting MIDI to Lilypond code. I have been working 
on improvements and will continue to do so, but I first have to improve my 
python skills a little bit.


The midi2ly from the current lilypond distributions fails most of the 
time when the time signature is not 4/4, it does not properly read key 
signatures, it does not like tied notes that pass barlines, to name just 
some of the problems.


Due to it's nature MIDI will never be the ideal fileformat to produce 
music notation, but even then midi2ly should do a better job in the future 
than it currently does. I hope to continue my efforts soon, but if anyone 
else wants to pick up the challenge before I do ... please do.

First of all, the PATH setting that was mentioned in a previous email 
should automatically be done by the LilyPond installation program, but 
you may  have to log out and then log in again after the installation 
for it to work.


Secondly, you should just specify the command name, not any full path. 
For example, if you just type the command

midi2ly
you should get a printout like:
Usage: midi2ly [OPTION]... FILE

Convert MIDI to LilyPond input.





Last time I tried, it did not work.  See

http://code.google.com/p/lilypond/issues/detail?id=834


I just tried it right now with LilyPond version 2.13.8 and midi2ly 
certainly works on a small MIDI file that previously was generated by 
LilyPond, so the above mentioned problem does not happen for all MIDI 
files, so if you are lucky it will work with your MIDI file. However, 
don't expect too much from midi2ly since it has several limitations. 
Especially, if often results in weird note durations, since it 
interprets the MIDI file too literally.
