This might be a silly question,but how do
you make your own drumkits? Ive looked through the docs and info at the Sourceforge site,but cant see any reference to it. Or am I going blind?!!
Any help would be great. Many thanks for
the great drum-machine,and keep up the
the good work.

 Hydrogen Rocks!

Thanks to comix, I had got a hold of the cvs before he posted it. And with his help got it running on my systems. 0.9.2's new UI is great. Much clearer, faster. Using Hydrogen to create fill in drum tracks for DJ friends has never been easier. I Use ReZound (It's not a KDE but wow, it's a good Audio Editor http://rezound.sourceforge.net/) to add the drum tracks into the dumb blank spots some artist add to their dance music.

Comix, home run my little drone! Hydrogen is a must if you work with music, especially if you're a DJ (a dying art).

Now if only I can convice Markey to build a DJ version of amaroK!

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
