MODUI Update

Hi guys!

Is there a way to update zynthian’s MODUI to the latest version released?

The latest version already allows the loading of impulse responses in an LV2 plugin



Hi @rod_amaral!

@steveb has been maintaining our modified MOD-UI fork:

The latest sync is from 3 months ago. Perhaps he wants to sync it now … :wink:



Hey, I am very interested in loading impulse responses, so I will update this soon. I’ll aim to do it this weekend


I’ve updated our fork with the latest mod-ui, and I’ve proposed a pull request to add the new cabsim-IR-loader plugin.

I can’t get the plugin menu to show my IR files though, it only shows the default forward-audio_AliceInBones.wav. Its not clear if this requires some integration with some other component of mod-ui. All I’ve really tried is putting impulse files in /zynthian/zynthian-plugins/lv2/cabsim-IR-loader.lv2/ and restarting. Also reading all the source code to figure out how it loads the IR list.

If someone else wants to dig into this that would be most welcome.


With these 2 pull requests I now have a fully working cabsim plugin!

There is a File Manager icon on the bottom left which allows you to upload IR files to the ‘Speaker Cabinets IRs’ directory


Hi Steve!

How can i update to this version?


Run scripts/recipes/ in zynthian-sys. It will install whatever version of mod-ui is in branch zyn-mod-merge

Thanks! I will do the update tonight, I saw that the master repository has already been updated!

I will share some impulses reponses that I have:

Hi Steve!

I managed to update the zynthian, however the IR Loader has no sound.

Any trick?

Only the first 128 samples of the file are used, so if there is a moment of silence at the beginning of your impulse samples then you won’t hear anything. See this comment and thread.

Hi @steveb ,

I have the problem that the new file browser (I think it is the fourth icon on the bottom left) does not work in Firefox (on Linux). Can you confirm this or is there something wrong on my system?
