Can't Upload Soundfonts[SOLVED]

Hi Zynthians,

i try to uplod some Soundfonts, but i get only Errors.
If i use the green upload button, it came the Message:

“500: Internal Server Error”

When i try to install some soundfonts from the “Search Musical Artifacts” Option, i get these Error:

"Can’t install URL: type object ‘zynthian_engine_fluidsynth’ has no attribute ‘zynapi_install’

Drag& Drop don’t work, the System saves the File on the PC.
I use Windows 10 with Firefox.

Have anyone an Idea?

Thanks for Help.
Regards Mario

Yes. Sorry! We commited some changes by error and now the development version of the new Preset Manager is merged with Master. I don’t want to go back because it’s a bit of a mess and the new Preset Manager is almost ready, but “install from search results” and “upload” features are not ready yet. Please, be patient. I will to improve it along the next week …

Until then, you could try to upload the soundfonts directly to the zynthian using SFTP. You have to place your fonts in “zynthian/zynthian-my-data/soundfonts”, but please, look at “/zynthian/zynthian-sta/soundfonts” and mimic the directory structure. Note that “sfz” and “gig” have subdirectories (banks), while “sf2” no (each sf2 is a bank).


Hi jofemodo, thanks for the tip.
With sftp it works great.
But, i have tons of wav files, and don’t like to convert it in soundfonts.
If there an option (Sampler) for use wave files in zynthian?
Exampler and samplv1 i have installed, but can’t find the directory where the wav files must uploded.

Currently it’s not easy to do. We need to improve the samplerv1 integration. In the current state is almost unusable. Sorry …

Hi @marber68!

I just updated the preset manager and soundfont uploading it’s working again! (and improved!!)



Hi @jofemodo!
Thanks for the news.
Thats great, good job.


Slightly different behaviour but same high-level issue - I can’t see my SFZ after uploading.

  • Navigate to http://zynthian.local/lib-presets
  • Select “LinuxSampler - SFZ/GIG Player”
  • Click Upload button
  • Drag zip to browser and click Upload
  • Can’t find the zip on Zynthian and does not appear in list of SFZ instruments

What am I doing wrong?

You are not providing logs… maybe browser JS log as well
