Like you can know, Timidity has a basic mapping of 47 notes
- 46 if we count the two kicks: Acoustic Bass Drum (bda) and
BassDrum1 (bd) for one - which follows (I think) the General Midi
For Hydrogen there are only 32 notes available in a drumkit
which begin from c1 to a4 (I'm not sure if I recall right)
Well. Now you have started Hydrogen.
And then Rosegarden for instance.
You have checked out your connections in qjackctl (Alsa and audio)
for me  in Alsa
  3:out1-General MIDI Device -> Hydrogen Midi-in
	in Audio
  Hydrogen Out_L and Out_R -> system

and don't forget in the Hydrogen's pattern editor to press the
little icon - a red 0 in the middle of panel RECORDING - it becomes
completely red.
Start your Lilypond file. You listen to your file.
But depending of your midi file and your drumkit you are surprised with 
the result.
Yeah! Sometimes it's funny.
Because there isn't a whole correspondence beetween the General Midi of
your Lilypond midi file and the Hydrogen drumkit.

If you're interested I've made a drumkit in two parts (in fact 2
drumkits ) for Timidity
Timidity-part1 = 32 notes
Timidity-part2 = 14 remaining notes
and a conversion of the timidity's samples in wav.
It's a good start before you improve the quality of the samples.
I assume you know how to install a drumkit.
I'll can put them on my site for some days. (~7 Mo)
