Let's make some noise ....

A CD40106-based drone generator - no real changes from the original design: four channels of the 40106 set up as tunable(ish) oscillators, mashed together using a CMOS logic chip and then output through a Sallen-Key filter. Throw in the current-starve option and sonic wackiness can often ensue.

Use it as a standalone drone generator, as it's capable of producing some fairly dense textures in the right hands, or use it with an envelope generator and a VCA and you've got a source of nice, clashy percussion sounds.
