Do you mean the defaults that are displayed by analyseplugin? If so, I wouldn't call that a preset, in that it is a single set of default parameters provided exclusively by the author. > LV2 presets are also part of the LV2 API/namespace, and are host-neutral. > > Load a plugin.

You may be correct in theory, but the top search hits suggest that practice is otherwise: In this third hit on Google, titled "LADSPA Vocal Effect Presets" the author is distributing his parameter settings as screen shots. http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=0ahUKEwjPn5zw_rjMAhVD32MKHXpmDpUQFggpMAI&url=http%3A%2F%2Flinuxaudioblog.com%2F%3Fp%3D262&usg=AFQjCNH_rrbcFwo7EdO-62gjvfpeIp7ttg&sig2=Ns7qj1KsjsZwkUgxclMO1Q&cad=rja Another hit is Guitarix documention, describing differences of Guitarix and LADSPA plugins. https://sourceforge.net/p/guitarix/wiki/How_to_use_the_new_ladspa_plugins/ Simple LADSPA plugins can just be added to a track, maybe some parameters adjusted, and you are done. In contrast, the Guitarix plugins need a preset file which is generated and modified by Guitarix, and the meaning of the 5 assignable LADSPA parameters depend on the settings in the preset. The audacity docs also rank high. This is important because Audacity is so widely used. http://manual.audacityteam.org/man/effect_menu.html LADSPA effects support real-time preview. They do not support import/export of presets but do support saving presets for use in Audacity only. Another part of the Audacity manual says: Many VST effects support import and export of named factory presets in a single FXB file, but LADSPA and LV2 effects do not support import and export of presets at all. So if there is a standard for exchanging plugin parameter sets, I haven't seen it, and it is invisible to Google (invisible == not appearing on the first page.) Almost everyone who uses a DAW for audio production has their own sets of preferred plugins and parameter settings. Where are these being shared? Can we do better? -- Joel Roth _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
