i really recommend this software to anyone interested in synthesizing their own drum sounds. -> http://www.waldorfmusic.de/en/archive/attack.html
drum synthesis is a little different than other sounds. it's really fun once you get the hang of it. the software can also do really strong synth sounds too.
yeah this looks boss but haven't had a chance to play around with it yet though.
still a big fan of micro-tonic, too!
