I think you mean the FluidPlugs? They are LV2 wrapper around a soundfont (I think based on fluigsynth). Currently they use hard-coded soundfonts. The current lack of MOD-UI seems to be that you have no file browser for selecting soundfonts/samples/sysex/IRs/…
I own a MOD-Duo - for this device the MOD-UI is primarily written. MOD may want to create a file browser, but this may be far away on their to-do-list-of-death. So the only solution is to create a wrapper or to extend MOD-UI (it is freely available on github).
Maybe the following idea s a way?
- write a generic LV2 plugin (based on the FluidPlug?) which loads its soundfont from a file that is named like itself.
- use a seperate web-server on Zynthian for uploading soundfonts
- after uploading the soundfont an automatic creation of the generic FluidPlug-LV2 in combination with the installation of the soundfont is done in the plugin folder.
So you have not to build a new hard-coded plugin for every soundfont… when I have time I will ask the MODs what they think about this and start to code…
