Just to clarify, I’m not related to MOD at all, I’m just a user who recently bought a MOD Dwarf and wanted to create a new sound. As for DuoX I can’t help with that as I don’t have one to test.
If anyone else wants to try though, I’ve kept a plugin template here which allows them to write new plugins faster. GitHub - stefdoerr/mod-plugin-template: A template repo for developing MOD/Dwarf audio plugins · GitHub
But the fastest way to write new plugins is probably the official new AI plugin builder The mod-plugin-cookbook: using AI to create new plugins - #31 by oeSmash
