GMSN! Pure Noise Eurorack Module

Regular price £7.50

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

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.
