I did not have the "lv2ls" command, so I installed it like this: sudo apt-get install --yes lilv-utils
Unfortunately when I execute "lv2ls", it shows that I have no plugins installed (i.e. it does not return anything). But this is where I can see the plugin files on my system: root@22f908a93c0b:/data# *ll /usr/local/lib/lv2/sdenoise.lv2* total 160 drwxr-xr-x 2 root root 4096 May 9 21:55 ./ drwxr-xr-x 3 root root 4096 May 9 21:55 ../ -rwxr-xr-x 1 root root 229 May 9 21:55 manifest.ttl* -rwxr-xr-x 1 root root 147216 May 9 21:55 sdenoise.so* -rwxr-xr-x 1 root root 1991 May 9 21:55 sdenoise.ttl* And you already know what's in that *manifest.ttl* file (from my prior email). I must be doing something wrong but I don't know what it is.
