One technical problem of such a general feature, is that some MIDI commands that are intended to apply to all MIDI tracks should be inserted in track 0, whereas other MIDI commands (that contain a channel number) should be inserted in the same track as the corresponding music. Another complication (at least conceptually) is the different concepts used in LilyPond and MIDI and how they are mapped to each other. By default, MIDI channels correspond to Staff contexts in LilyPond, but this can be changed by redefining the context definitions in LilyPond. A final complication is the lack of standardization of MIDI.

See http://lists.gnu.org/archive/html/bug-lilypond/2003-10/msg00069.html for some related information.

Aren't you using a synth with a vibrato channel then?

Of course. Not sure what you are thinking of with all these questions.
Point is that if I could generate MIDI messages in the score I could do what I want.

Yes, I see that now. I was thinking of entering it in a musical way. But it is good if one can have all sort of MIDI output tweaks - time bends, too, for example, otherwise people may try to handle by writing strange meters.
