In lilypond, simply use the \tempo command:
http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Metronome-marks#Metronome-marks

That puts the quarter=120 above the staff. Is that where you need it? 
Otherwise you'll have to fiddle around with the #'direction and #'side-axis 
properties of MetronomeMark to move it left/right or below/above the staff.

If you need more advanced metronome marks (e.g. "Fast (quarter = 220-220)"), 
you'll have to use a markup (which unfortunately has no effect on MIDI). See 
the LSR snippet for a scheme function definition to simplify their 
generation:

musicxml2ly does not yet convert any metronome marks.

It should should not be too hard to implement, though, if anyone is 
interested: <metronome> is simply a direction subelement, see 
http://musicxml.org/dtds/direction.html for the syntax, which can be 
converted similar to <rehearsal> or <segno> or <coda> (see the code for 
these)

Hmm, musicxml2ly has limited support for  percussion staves, but at least it 
should produce some output... Which version of lilypond are you using? If 
it's 2.10, then musicxml2ly has only really basic functionality, in 2.11 it 
gained a lot of new features.

Is there any error message on the command line?
You can also send me the .xml file via private mail, so I can check the 
problem myself.

Well, yes (if I count myself as part of the lilypond developer team...). I've 
done most of the work on musicxml2ly recently (as said above, all that is 
only in 2.11, but not in 2.10, because i started development long after 2.10 
has been released).

Cheers,
Reinhold
