Hexinverter.net - vcNOIZ
The Hexinverter.net - vcNOIZ is a truly beautiful recreation of the generators that were used in Atari machines. Its digital noise and square waves will satifsfy a lot of audio duties, let it be pixelated synth lines or percussion with the right amount of controls on the front panel.
Hexinverter.net - 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!
- 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 the manufacturers figured this could be useful
Module Width: 6HP
Module Depth: 38mm
Current consumption: +35/-30mA @ 12V
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.
