> http://waldorf.electro-music.com/attack/docs/attackdrumsounds.pdf Thanks Malte, this is some great info! It's very reassuring that the 'classic' drum machines don't create their drum machines through a secret ritual ceremony involving straw figures and pin pricks. >From what the text says, my 'hard snare' sound is very similar to the Roland 808 hand clap. It's beautiful how all these different musicians use different techniques to make people feel good. We code our asses off and introduce two exponential envelopes to a white noise source, and African Americans build cathedrals and clap their hands in them. ;) Much appreciated, Malte. Carlo
