For example one thing I noticed in Ardour is when you open a LADSPA plugin window Ardour still 'grabs' keyboard shortcuts (e.g. SPACE to play, HOME to rewind); open an LV2 window and I'm most often hitting HOME to rewind just to discover I've set the parameter under focus (usually a shiny knob) to its minimum value :) You can disable this by clicking on the keyboard icon in the upper right corner of the plugin window. That will give the plugin window the opportunity to grab+use all keyboard events. Take 2: What I think you're differentiating between are not actually the same situation. I think (but am not sure) that when you refer to "an LV2 window" you are talking about plugins which provide their own GUI entirely, rather than the ones that provide a object that the host can embed in its own window. This design is now deprecated by many who work on and around LV2.
Yes that's the use case I was referring to, and just after scolding myself with a RTFM, I actually saw that the keyboard icon is there only on LADSPA plugins (at least on my system). An example of the use case LV2-wise would be one of the Calf ones...
There's really no way for the "external GUI" approach
to ever provide the same keyboard handling as the embedded approach. By comparison, on OS X with AudioUnits, there is no "external GUI" option: the plugin's only choice is to provide an embeddable object, thus allowing the host to control and provide for a consistent keyboard experience.
Up to now I must say that probably the only real use case for having a (graphical) gui for plugins is maybe compression / limiting etc. where you can see graphically when and how the effect is actually 'kicking in..', although this could probably generalized. Otherwise just parameters for me lets me really concentrate on the (sometimes subtle) *audio* differences in tweaking parameters... But again I'm probably a bit of a corner case user.. :)
Anyway, thanks Paul as usual for providing detailed insight. Lorenzo _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
