The GMSN! Pure Noise outputs 4 different colours of noise: Pink, White, Red, Brown.
Each 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.
