MIDI control of LADSPA Plugins

I’m not sure if this is already possible in Linux.
Please tell me if it already is.

Take this screenshot:

Imagine if you could assign the LADSPA plugin parameters to endless encoders
on a BCR2000. You could have all those plugins open and control them
with a MIDI control surface(BCR2000, BCF2000, UC-33e,etc) in Ardour.

Knobs, faders, buttons, etc would all work via MIDI. Maybe you
could also save these settings to a template and load/unload them at will.

its already possible although mapping the N controllers to >N controls is not solved.

just enable generic MIDI control, and then ctrl-middle-click on the plugin GUI control. same as for faders etc.
