AFAICT the choices are:

1) Ardour, has extensive MIDI bindings, but didn't bind "pop-up menu" parameters to MIDI last I used it
2) AMS
3) Ingen (experimental and you have to chase SVN to use it)
4) ecasound, though you have to add lots of weird command line switches to define MIDI bindings
5) JACK RACK has MIDI support, though I've never gotten it working

Out of all the above, the easiest I found to set up for controlling LADSPA parameters was Ardour, though it had some limitations as described above.
