I have the same issue. Installed Musescore local and portable... I even switched between different Versions. Nothing works.

Try using the command line conversion on the terminal to see if it is successful:

MuseScore4 -o output.mp3 input.xml

I don't know much about all this stuff, but I'll give it a try

I interpreted your solution as meaning that I should manually convert the generated xml file in the output folder of Notagen via the command line. However, both the notagen_original and the notagen_interleaved are empty. This means that Notagen does not generate any outputs. I made sure to have all requirements installed and added MuseScore as a system variable again.

Here is the complete command line output:

It seems like the samplings package is to blame or am I wrong?

Hi,

I tried the MuseScore CommandLine with this two commands with success:
MuseScore4 zzz.xml -o zzz.mp3
MuseScore4 zzz.xml -o zzz.png

I downloaded a sample XML-File from here: https://www.musicxml.com/music-in-musicxml/example-set/
Renamed it to zzz.xml and put it in: MuseScore\App\MuseScore\bin

MuseScore successful created both files, a zzz.mp3 and a zzz.png.

When I run the node in ComfyUi the notagen_original and the notagen_interleaved are empty, so there are no files to convert.

same problem

[jannismelle]

Thanks to the developer's advice, I found out that only the notagen_x model is able to use the period-composer-instrumentation principle. Everything works smoothly with the notagen_x model. As soon as you switch to the small medium or large model, the process stops. It's even on the official Github page of Notagen, but I must have missed it.

[jannismelle]

Now that it was working, I didn't pay as much attention to the console. However, every run is terminated by the following:

2025-03-23 17:47:41.923200 [r:45/5][V:1](3(!>!_G!>!F!>!G) (!>!_d2 _c2)|[V:2]z (.[_D,A,_C].[A,C_D].[D,A,C]. [A,CDD:\User\KI\StabilityMatrix\Data\Packages\ComfyUI\venv\lib\site-packages\samplings\__init__.py:351: RuntimeWarning: divide by zero encountered in log

Prompt executed in 389.92 seconds

I'm not sure if it's some kind of error or something, since it generates usable results. I just wanted to bring it up. Seems to be similar to the log of this issue. Only in this case does it occur at the end of a generation process.
