vcNOIZ is a unique sounding voltage controlled digital noise source. The frequency of the noise is both linearly and exponentially controllable by analogue control voltage signals. It creates positively raunchy C64-esque digital noise and sounds great for hihats and other sounds as well!
There are no microcontrollers used in this design. It is comprised entirely of CMOS logic and analog opamps, so does not suffer from aliasing or any other issues present in a microcontroller-based design.
- Expo. response CV input (-V to +V)
- Linear response CV input (-V to +V) -- great for audio rate FM, as the audio demo shows. It sounds positively gruesome!
- Clock input (square wave, positive logic)
- Pitch control (to tune base frequency, just like a VCO)
- Base frequency noise output (a little smoother sounding than the divisions) [audio coupled]
- Sub octave /4 output (gritty sounding) [audio coupled]
- Sub octave /8 output (gritty sounding) [audio coupled]
- Base frequency DC coupled gate output (for when wanting a random gate when using a slower clock/pitch rate)
- Internal clock output (there was an extra opamp, so I figured this could be useful)

DIY PROJECT DATA
The vcNOIZ DIY project is available as a full kit which includes the PCBs with the SMD components pre-soldered and the 6HP eurorack panel. THIS IS A DIY PROJECT AND WILL REQUIRE ASSEMBLY! (The module photo above is of the completed product: not what you will receive!)
