The drums were created by using only one noise source and then sending it to Agave’s Low Pass Filter Bank. Each of the bank’s outputs go into its own ADSR. Changing the release on the ADSR will have the most effect on the different drums.
The top row has a couple of VCOs for some semi-melodic noodling. They can be muted on channels 7 and 8.

If this is your kind of thing, I’ve got a whole album on soundcloud that uses only filtered polyrhythmic noise (Yeah, that’s right…a whole album). https://soundcloud.com/worker13/tracks
