Noise Generator

Version 0.2 from November 2020

Noise generator that I built for my modular synth drum machine project. It includes white and pink noise for the basis of hi-hats and a snare drum. The circuit needs at least +/-12V to run.

The design is based on “2tran_wn.gif” by richardc64 via (white noise) and “Noise source with passive filter” by SyntherJack (pink noise filter).


Improvement Potential

While plugging in the oscilloscope for the first time, I just realized the DC bias in the white noise – to be removed in future development.

Wait, there's more?
