I recently installed Reaper on my desktop running Nixos 24.05 and whenever I install a VST (either manually or through the package manager) it ends up in Reaper’s “plugins that failed to scan” section without producing any error messages.
Curiously enough, Ardour too fails to scan VST3 plugins but has no problem with VST2.
Here’s what I’ve already tried:
-Installing musnix
-Reinstalling Reaper multiple times either as a system package or a user package
-Reinstalling the plugins in question multiple times either as system packages or user packages
-Changing permissions for my .vst and .vst3 folders through chmod
-Manually setting the VST_PATH and VST3_PATH environment variables
For Ardour, is VST3 support enabled in Edit > Preferences > Plugins > VST ?
You can see what paths it’s searching by clicking the Edit button for Additional VST3 Path.
yes it’s enabled and it seems to be searching the right paths
I see. What plugin are you trying to load, exactly?
The plugins i’m trying to load are Vital and LSP-Plugins.
Another thing worth noting is that right now i downloaded the Quetzalcoatl VST3 plugin from github and it seems to scan and load just fine both on Reaper and Ardour
I don’t think Reaper reads any environment variables for paths, so you might have to add them manually to Options > Preferences > VST > Edit path list. For me, adding /etc/profiles/per-user/username/lib/vst3/ made Vital and lsp-plugins detected.
You might also need to try other re-scanning methods if it still fails, like Clear cache and re-scan VST paths for all plug-ins.
In Ardour, everything is detected fine for me. You might need to go to Window > Plugin manager > Re-scan All and see if it detects them
The /etc/profiles/ directory does not show up for me. Should it be generated by default or do I just make one?
That was just an example. I have it installed system-wide with home-manager, so that’s the path for that. You should just add all the paths from $VST3_PATH
Setting $HOME/.nix-profile/lib/vst3 as a plugin path in Reaper seems to have fixed everything tysm
