As far as I know there is not a commonly accepted MIDI file event for 
Clefs, like there is for Time Signature (FF 58 04) and Key Signature (FF 
59 02). But I guess it is possible for a Sequencer like Rosegarden to put 
a special message in a "Sequencer Specific Meta-Event" (FF 7F). Or in a 
text event (FF 01) which, according to the Standard MIDI-File Format Spec 
1.1 that I'm looking into now, can contain "Any type of text containing 
anything".

Personally I would not choose to let Lilypond/midi2ly be able to export or 
import such a non-standard Clef event.
