One thing that we need to figure is how to handle them. Presets shipped with the
plugins (regardless of ladspa or lv2) should go to $prefix/share/... (e.g.
/usr/share/ladspa/presets). Idealy it would use the same basename as the so uses.
Application need to be prepared to read presets from there, but store (and read)
them in the users home directory. For merging I would suggest to read the system
wide presets and then read the user-presets - in case of a double entry the
Ardour stores them under $HOME/.ladspa/ardour.n3, that could be a bit
problematic if other apps want to use them too. Using separate n3 files for each
plugin and ev. even require to use flock on them would help to avoid conflicts
(yes I know the limits of flock, but is there anything better?).
I would prefer if the location is in sync with the freedesktop user-dir spec also.
