Hexinverter VCNO

MUSICAL FEATURES

VCNO is a noise oscillator that can generate full spectrum white noise and a wide variety of random signals. VCNO isPitch can be modulated with CV, allowing outputs with different acoustic characteristics to be used simultaneously. It can be patched into a VCA and used as a sound source, or as a trigger or modulation source for other elements of a modular system.

The main difference between a typical Eurorack fixed noise generator and a VCNO is how the noise is generated.Instead of using a fixed white noise generator as a noise source, the VCNO uses a variable frequency linear feedback shift register (LFSR) to create a pseudo-random sequence of bits (square waves).When these occur at frequencies significantly higher than the audio spectrum, the resulting sound that reaches us becomes full-spectrum white noise.Although this method of generating noise is technically digital (like the C64's SID sound source chip), VCNO uses discrete analog hardware instead of a digital microcontroller. Implemented.

Demo videoNow you can use an oscilloscope to see how a random pattern of square waves is interpreted by the human ear as pure white noise.

• Generate everything from pure white noise to crunchy noise reminiscent of vintage game soundsNOISEoutput
• DC-coupled, also perfect for random triggersGATEoutput
• SCREECH, SIZZLE, and TEAR outputs each have different acoustic characteristics
• SIZEThe output is equipped with a tone control using the output from white noise.
• Generate sounds like a broken noise generatorLOOMoutput
• All outputs are available at the same time and are also affected by the Pitch knob and CV at the same time
• Pitch frequency can be modulated with any CV signal.Can be finely adjusted with a dedicated attenuator
• CV signal response can be selected between logarithmic and linear via a switch on the back of the module
• Bypass internal frequency generatorCLOCKinput.By inputting the clock from the trigger sequencer, you can create pseudo-random triggers that are synchronized to the pattern.
