[linux-audio-user] Hydrogen advice needed: how to achieve this sound?

Hello everyone, I'm new to drums and drum machines, trying to work with Hydrogen. Want to do some home recording with bass and guitar. Need a cool drum groove to play with and try to make that from scratch (love to learn :-). Take a listen to this and you will know what I am talking about: http://hit.tweakdsl.nl/hh-beat.mp3. It's a little less than 500kb in size. It's the hi hat that I want. The rhythm isn't so complicated, just a beat on every count. What I can't get is the same sound as the recording. It's lush (not quite a closed hi hat, I presume) and has a long decay. So far I've only achieved a mechanical sound. So the questions.... Q1: is what I want at all possible with Hydrogen? Q2: can this be done with the standard GM drum sounds? Q3: if not, what kind of samples/drumkits should I be looking at? Q4: apart from delay, are there any other effects I should use? Q5: or is my approach to simplistic and should I try more complicated patterns with more sounds at the same time (e.g. open and closed hi hats)? Hope you guys can give some advice or insight. BTW, the clip is from the song Amerimacka (feat Notch) by Thievery Corporation. Cheerio, Hans Debian GNU/Linux testing, Athlon 2500+, SB Audigy 1
