Hi! I created a package for https://github.com/DISTRHO/DISTRHO-Ports. I now wonder if I should submit a patch, because the licensing situation is a mess, with several of the plugins having no information attached at all, though most have at least a pointer to a repo that claims a license (gpl2, gpl3, gpl3+, agpl3, MIT).
The original versions of all plugins have been created with JUCE, which I though would require GPLing when using the free/personal license, but at least currently does so only when exceeding $50k revenue (https://juce.com/juce-6-licence). So parts of this is Free Software, other parts are ... just technically open-source. Would you accept this in Guix? -- Thorsten Wilms
