I don't need a new drum machine; I need to watch Robert Henke's tutorial on Operator a few times
Came across this superb short tutorial on making your own drum sounds by genius artist and Ableton co-creator, Robert Henke aka. Monolake. Not only does he quickly create some passable 808 style drum sounds, the journey to each sound is a lesson and offers some interesting sounds along the way. Having met him a few times I can also say that Mr Henke is a thoroughly decent chap.
