I’ve not used Audacity for some years and now I’m back but I seem to remember you could download additional Nyquist plugins in one package. In particular I’m after a ring modular effect but I’d like all of them in one package. I have searched here and elsewhere but I’m a bit rubbish!
There isn’t a “package” of Nyquist plug-ins, and because many of the published plug-ins are very much “minority interest”, I really don’t think it’s worthwhile for us to provide a big bundle of them. There is a list of “officially published” Nyquist plug-ins here: https://wiki.audacityteam.org/wiki/Download_Nyquist_Plug-ins
