The Erica Synths Black Code Source is a true stereo digital noise or dual random CV generator, using a complicated calculation of polynomials of various configurations.

The developers say that the module will fit ideally in percussion synthesis or random, self generation patches. The Code Source also can be used as an extreme effects unit to bitcrush and destroy sounds in radical ways.

The Black Code Source Expander takes the Code Source to next level by adding autobend feature and more noise/CV modes.
