vcNOIZ -- A DIY Voltage Controlled Noise Source for your modular


Published on Sep 21, 2012 by hexinverterDOTnet

"This is a very early preview of a voltage controlled noise module I am working on. It is of course designed for use in an analog modular synthesizer.

That is, the pitch is controllable via control voltage signals, which makes for a very interesting sonic palette.

If there is enough interest, I will make a circuit board and have it for sale in the hexinverter.net online shop.

All of the parts are pretty commonly available and should make for a pretty fun project to put together.

This design differs from a lowpass filtered white noise source, because a lowpass filter would likely alter the edges (and thus the sonic characteristic) of the noise. Because the noise source itself is generated by a digital shift register, harsh digital noise reminiscent of the C64 and NES will be possible at all frequencies."
