The ASM-1 NOISE Module


The Noise module provides the basic material to produce a whole spectrum of sounds that do not have a defined pitch. White noise can be used to produce sounds such as wind, rain and surf. `Coloured' noise, which is white noise with the low frequency components boosted, is used for sounds having a strong bass content, such as the rumbling of thunder.

In addition to modulating the VCO signals, noise can be added to these signals to simulate wind noise in organ pipes and woodwind instruments.


        • White Noise (~5V peak-to-peak)
        • Pink Noise (~5V peak-to-peak)
        • Random Voltage (~5V peak-to-peak)
