vcNOIZ is a unique exponentially controlled noise oscillator for analogue synthesis. It creates absolutely crunchy sounding Commodore 64-esque noise.
It is useful both as a pure noise oscillator as well as a random gate, voltage-controlled clock and even for use as hihats!
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)
