ardour doesn't use the sequencer.

and i don't consider the nrpn messages any different from any other
controller. from libmidi++'s persepective, there are 127 controller
ID's, each with a value. whatever standard mapping they may have to
gain, pan, or nrpn is completely ignored.

14 bit value support is almost impossible to provide: the midi spec is
just ridiculous for that.
