[LAU] Playing lilypond midi drum files with synth/sampler

[Grammostola Rosea]

Hi,

I want to write drum score in lilypond, export it to midi and play that 
with a sequencer.
Which programs are the best for this? Muse, Rosegarden, Qtractor? 
Linuxsampler (gigedit) or specimen?

How does the mapping work? The sequencers do use standard midi 
percussion maps...(?)

Here is one: http://www.midistudio.com/Help/GMSpecs_PercMap.htm

Key 35 is that key 35 on a 88 keys piano from left to right?
so key 35 is G3?

Thanks in advance,
