Noise oscillator with multiple types of noise, color modifications, bit reduction, and modulation capabilities. The Noise Oscillator module generates three types of 'noise'. An additional sine wave can be mixed into the noise using the color knob.


Oscillator features coarse control knob, fine control knob, and color control knob. Coarse control knob takes a range of 65.41 through 2093.00, which correspond to the notes c2 through c7 under a440 tuning. Fine control knob allows pitch to be adjusted up or down one half of an octave. Color knob adjusts sine wave mix. Bit reduction knob adjusts bit reduction amount.


Color knob and CV input jack adjust sine wave mix. CV input jack signal can be attenuated using the amount control knob.

CV Control

CV signals can be used to control pitch, hard sync, and color of the output waves. Pitch is controlled at a conversion rate of one volt per octave and is summed to the values taken by the coarse and fine control knobs. Color CV signal can be attenuated using the amount control knob; color CV signal is summed to color control knob values.


Noise Oscillator outputs three noise types via line level output. All three noise types can be output simultaneously.
