Thanks Philippe!

I was wondering, is there information available to learn putting those 
beats into notation? What 'symbol' belongs to the bass, hi-hat etc.
Is there information on the internet about it? Or does someone knows a 
other method (good book) for it?

And how easy is it to match the notes with a drumkit in for example 
hydrogen? I think it should possible to play the drum score in 
Rosegarden with Hydrogen as a synth..
