Opening PDF with Audiveris in MuseScore


By using Audiveris and MuseSCore you can import PDFs in MuseScore, as shown here

I'm trying to install Audiveris as a plugin in MuseScore as described here

Starting MuseScore I get the following message "C:/Program Files (x86)/MuseScore/plugins/audiveris.js in line 1: Syntax Error: Parse Error"

Line 1 define the location of Audiveris this way: var audiverisHome = "C:/Audiveris4.1beta";

Does anyone have any idea what might be the problem?

All help would be appreciated!

Works just fine for me. I had to rename the Audivers dir though to match the entry in the plugin (could have done it in there instead)

Hey, lasconic: why isn't this plugin available on the plugins page?

Because Audiveris 4.1 is still in beta. The plugin was a quick hack during Music Hack Day Boston. Moreover it works only on Windows for the moment. So I don't want to expose it on the plugins page just yet.

I believe to have found an issue with the plugin: it is lacking the init function. This seems only to lead to errors if it is the 1st plugin in the list, could that be? It usually would be the 2nd, after ABC-Import, but becomes the first when instelld in the user's plugin dir rather than the system one.

However, the fix is simple: just add an empty init function, like the plugin documentation says:
function init () {};

BTW: I've translated it into German, attached

locale_de.ts 1.92 KB

init has been added. Good catch.

It complains

 omr.ui.symbol.MusicFont.checkMusicFont( -- SEVERE: *** MusicalSymbols font not found. Please install MusicalSymbols.ttf ***

It works though, sort of (the result is not as usefull as I hoped for).

Where to get that font and where to to it?
Well, actually this, again, is more an Audiveris problem, than one of the plugin... but maybe you know anyway?

Can this be the font you ar e looking for

My fault! Used Notepad in Windows to edit the .js file, and your answer reminded me that Notpad aint’ the right tool. Edited the .js with Notepad++ and now the plugin is available in MuseScore. Thanks!

But: Seems like I can’t get Audiveris to perform the OMR process. Have tried with several PDFs and a .png fila but the analyzing process stops with: “Conversion failed: No MusicXML file generated” and last lines below reads:

omr.Main.doMain( -- INFO: Checking 1 task(s)
omr.Main.doMain( -- INFO: SHUTTING DOWN ...

That seems to be more an Audiveris issues than a MuseScore one, isn't it?

To get better error reports when importing an image, modify the file "audiveris.js" located in folder "plugins/audiveris" of MuseScore installation folder.
Around line #51 of file audiveris.js, before or after the "-batch" parameter line, insert the following line:
"-option log.Logger.printStackOnWarning=TRUE",

This option tells Audiveris to print out the call stack whenever an exception is encountered (this option will be on by default in next Audiveris release).

You can then publish the log in this MuseScore forum, or directly in Audiveris issues at


Thanks for the tip. I added this option in the plugin.

My mistake! The correct constant name is omr.log.Logger.printStackOnWarning (and not log.Logger.printStackOnWarning as written too quickly in my previous post)

Corrected message:

Actually it is in line 64.

It's now fixed at github. Also added a link to Audiveris home.
You can download the plugin at :

you don't like my translation? Save for later?

I don't see the need to make the plugin more accessible in term of languages now. It's a small plugin, tied to Audiveris and Audiveris is still in heavy development. If one doesn't speak english or french, one will not report bugs to Audiveris.

In general, I don't support translations in my plugin. The current workflow for translation is too time consuming. When we will have an actual plugin manager and plugin translation integrated with e.g. that might change.

fair enough ;-)

Perhaps we should provide it with Audiveris zip archive.
For the time being, you can find MusicalSymbols.ttf on various sites, such as
Simply install the font in standard windows/font folder.

Nota: The font is mandatory for Audiveris to work, even when run in batch mode, because some symbols characteristics are derived from the font itself.


i have a similar problem and i really hope someone can make a suggestion since i'm no programmer, just following instructions works for me.
When trying to open the PDF with the audiveris plugin I get the following error:
"Error loading plug-in "C:/users/herairness/application data/local/muse/musescore/plugins line 90:
TypeError: Result of expression 'form' [null] is not an object."
Unfortunatelly I have no idea what it means, so any help would be appreciated!

You probably didn't unzip all the plugin files at the right place. The program complains about a missing UI file. Try to install the plugin again and restart MuseScore. See Plugins to learn how to install a plugin.

Great, thanks, I had missed the ui. But now there's another error, which i don't get because I've set the path to the file and it's not read only or anything. Help?
"Conversion failed. No MusicXML file generated:
Unable to access jarfile D:/Audiveris4.1beta/dist/audiveris-4.1beta.jar"

And is that file at that spot? Probably not, so you need to edit the .js to point to the right location

I have the same error with Audiveris in MuseScore when I tried open the PDF file with Audiveris (plugin):

Conversion failed: No MusicXML file generated
Error: Unable to access jarfile D:/Audiveris4.1beta/dist/audiveris-4.1beta.jar

In audiveris.js file find this line with /*comments*/

/*********** MODIFY THIS VALUE *****************/
var audiverisHome = "D:/Audiveris4.1beta";
/*********** MODIFY THIS VALUE *****************/

and modify the directory where you have installed (unpacked) your Audiveris file (from Kenai website), for example: C:/Program Files/audiveris-4.1beta-full-20120201 and save the audiveris.js file.

With Best regards anta

I tried modifying the value, but the same error occurs:

Conversion failed: no MusicXML file generated
Unable to access jarfile C:Program Files (x86)AudiverisLtdaudiveris-4.1beta/dist/audiveris-4.1beta.jar

I edited the js file using notepad on my windows 7, do I need to use notepad++?

Here is how I edited it:

/*********** MODIFY THIS VALUE *****************/
var audiverisHome = "C:\Program Files (x86)\AudiverisLtd\audiveris-4.1beta";
/*********** MODIFY THIS VALUE *****************/

Thanks in advance!

Try using
var audiverisHome = "C:/Program Files (x86)/AudiverisLtd\audiveris-4.1beta";
instead, i.e. / rather than \

I tried your suggestion and it gave me the same error. I'm going to reinstall and see if that changes anything. Thanks anyway!

Just in case it matters, Jojo's example had a mixture of "/" and "\" characters. I've not tried this but according to the previous post from Anta they all must be "/" forward slashes.

Oh, sorry...

YAY! It turns out the problem was that I used musescore 1.1 before and I just needed to download 1.2. Also the forward slash (/) was needed instead of the backslash.

After import and converted to MuseScore are the finished work editable? I see the last mail on this subject was last year.


If you can get Audiveris to create a reasonable MusicXML file for you, then yes, importing that into MuseScore will create a normal editabke score just like any other. But do realize that optical score recognition software like Audiveris is still highly experimental technology, so don't expect miracles.

I didn't understand nothing to convert a pdf file in the program musescore.
Can you help me? Thanks :-)

MuseScore can't convert PDF into any of its own formats (the upcoming version 2.0 might, not sure).
Audiveris can convert PDF to MusicXML and MuseScore can read that.
The plugin that is the topic of this thread is connecting the dot, i.e. calls audiveris with the PDF, lets it convert into MusicXML and opens that in MuseScore.
But don't expect too much, the result is not likely to be too usefull in most cases.

Ok, but I can't convert PDF to Music XML, can you explain me please?

Using Audivers and this MuseScore Plugin?
How does it fail, did you adjust the settings in the plugin, like decribed in this thread?

I put the plugin in MuseScore, but the plugin say Error: Unable to access jarfile D:/Audiveris4.1beta/dist/audiveris-4.1beta.jar; Why???

Is it there? Under this name?
If not you need to either put it there or modify the plugin code.

Did you install audiveris? Can you run it directly from your desktop? You don't really need the plugin for MuseScore - you can simply run Audiveris yourself, load the PDf, save as MusicXML, then load the MusicXML into MuseScore. The plugin just automates this.

But don't get your hopes up. The technology employed by Audiveris to try to "understand" a PDF and convert it to MusicXML is still very much experimental. It's still entirely likely that youd get better results faster entering a score by hand.

Have you tried latest Audiveris version (4.2) released just one month ago?
If not, please give it a try.

1/ Make sure you download and install latest Audiveris version (4.2) from
2/ Adjust the plugin content so that it points to the precise location where you installed Audiveris.
I don't have the plugin source available right now, but I think I remember there is a line similar to the following:
var audiverisHome = <path-to-audiveris-jar-file>
You have to manually modify this <path-to-audiveris-jar-file> so that it points to Audiveris jar file

hbitteur, I am no programmer, can you give me the correct line and where to find it in Musescroe, and which version of it. please.


If you have that plugin already, you should know where you have put it.
If you don't have if, get it from, place it as per, open the audiveris.js file with a text editor of your choice (e.g. WordPad, NotePad won't work) and modify is as per

@hbitteur: I' just downloaded and installed Audiversi 4.2, modified the plugin code in 2 places (the path to the jar file and the name of the jar file) and tried to convete a PDF. I got an alert:
Runtime Error!

Program: C:\Womdows\system32\java.exe

An application has made an attempt to load the C runtime libtrary incorrectly,
Please contact the application's support team for more information.

I'm getting this twice. I get it too, when opening and transscribing the PDF in Audiveris directly, so it is not connected to anything the plugin does.

It did finish though and the result looks quite OK, much better that I had expected from past experience.

What Java version do you have running Jojo?


I think you need to switch back to 1.5 or 1.6.

1.6 (actually 1.6.0_30-12) doesn't work at all:

Exception in thread "main" mentions that Java 1.7 is needed.
The latest and greates 1.7.0_10 doesn't solve the problem.

I found the installing and use of audiveris very easy. the only thing I needed to do was to get a Java update to 7. 10. No need for updates. my platform is Windows XP and the MuseScore 1.2. As far as I can see there is no errors in the peace.

The document was a PDF I already had on my computer.

It may just be the good air hear in Wales!!!!


Google hinted at my problem being related to VisualStudio and some Microsoft DLL.

Ok, I'm not able to do this, but if I give you the file, can you convert in format XML and send it to me to this email please?? the file is not a virus

Just download audiveris and do it yourself, it's not that difficult.
You don't need the MuseScore plugin, but even getting that to work is not really difficult, it needs to get adjusted in 2 places for Audiveris 4.2

So what dos the plugin do?

I seem to have by passed it!


It calls Audiveris in batchmode (i.e. without its GUI), feeds it a PDF and opens the resulting XML in MuseScore.

ok, I open audiveris, I load the PDF file, I click on store and press export but nothing works

I don't see 'Store'. Just 'Score'. I think you need to use 'Transscribe' first, then 'Export'?
The Audiveris manual might be of help here, ofline or online at

Hmm, apparently Score->Export is enough and creates an XML file

Se hai già digitato Audiveris nella casella ricerca della pagina italiana ignora questa righe.
In caso contrario vai a dare un'occhiata, qualche spunto lo troverai.

But audiveris have block the button transcrive...

For Shoichi= mi potresti aiutare tu almeno?? :-)

Under Plugins in audiveris there is one that produces an xml for musecore.
I find that the ap don't seem to be able to see repeats. It often gets the time signature incorrect. I wonder if there is a system for reporting bugs?

It dose not seem to like one of my favorite peaces "Blaenwern" HAVE A GO ANY ONE!!!

CIao Shoichi, ho eseguito tutta la procedura ma, non mi esce niente. Se me lo puoi convertire ecco il file e per inviarmela ecco l'e-mail ! Grazie

Is there someone who would be willing to help me and take the time to either convert 5 PDF's to xml for me, or show me how? My email is I have tried using audiveris but i am too technically stupid. What I am trying to do is take 5 lead sheets to songs that just have the melody line and chord symbols and I want to actually write out the notes for the chords as I dont do well with chord symbols. Can someone be generous with their time and help me?

Realistically, you'll get those lead sheets into MuseScore much faster and more accurately just entering the notes by hand. It isn't hard. Starting with the video tutorials on the main page, then also check out my tutorial on lead sheets specifically at

Hi Marc
Thanks for writing, but maybe I am not explaining my problem well enough, I wanted to import them so I would have a starting point to write out the actual notes to the chords on staffs below the lead. Does that make sense???

It does make sense. I'm not talking about that second part - turning the chord symbols into notes. I'm just talking anout the first part - getting the notes from the lead sheet into MuseScore. And what I'm saying is, you'll almost certainly get better results faster simoly entering the motes by hand, as opposed to trying to get some sort of automatic reading of the PDF. It takes all of a few minutes to enter the notes for a lead sheet by hand, but you could easily spend hours or days fighting with scanners and PDF reading software to attempt to get anything at all onto MuseScore. and then you'd still need to spend time fixing up the results.

As an analogy, say you had a YouTube video of a two-minute speech, and you wanted to get a transcript of that speech into Microsoft Word. Well, you could either spend hours or days fighting with software that might be able to transcribe the speech from the video, and then still spend time correcting the mistakes the software would probably make - or you could simply type it in yourself. Typing it in yourslef would almost certainly get you better results faster. And it's the same with teyng to get music into MuseScore via PDF versus simply entering it yourself.

,for instance.

Each to his own, of course, but once I got used to MuseScore I found that trying to scan files, importing MP3s etc. was a waste of time. My best strategy to date is to use a wide monitor and have MS taking up the left and central 1/3s and an image of the original score on the right of the screen.

Audiveris is a tool, as such one needs the skel to use it, I have had some good results with it and at the same time learnt a great deal on how to use MuseScore when having to edit the Audiveris tool.

Like MuseScore it is a development,
