A stereo noise/wind Eurorack module with selectable noise and filter modes

This Eurorack module provides a kind of wind or noise machine with four different selectable noise types, blue, white, pink, and a grainy noise (meaning that the there is signal peak only occasionally with the frequency of peaks being controllable by a potentiometer).

The module contains a state-variable filter with selectable modes, lowpass, bandpass, and highpass.

The output signal is send to two separate VCAs and two separate output channels.

There is CV control for the filter cutoff, which is following the 1volt/oct standard for the filter self-resonance, as well as CV control for the filter resonance.

Filter modes and noise types can be selected via two push buttons on the front panel. The selection does not only allow one mode, but also any combination of modes by pushing each button multiple times.
