Multi-band analog noise source
The GMSN! Pure Noise outputs 4 different colours of noise: Pink, White, Red, Brown.
A straight forward SMT build.
Each colour colour occupies a different area of the frequency spectrum and can be used for different effects:
White noise is flat across the whole audio spectrum and is good for snares, the classic techno noise sweeps and for sculpting windy types of sounds
Blue is high pitched and is good for synthesising hi hats.
Pink noise has the same amount of energy in every octave and is often used as a reference signal
Brown is a low frequency brownian motion. When paired with a Sample and Hold module, this can give a good random walk bassline.
