1. Introduction
Module A-117 (DNG) is a combination module, inclu-
ding a digital noise generator and an 808 source.
The digital noise generator uses random sequences of
square waves, (18-band, with multiple slewed feed-
back loops), whose rate can go from random clicks to
pure noise. The colour of the noise is very different
from the analog noise produced by the A-118.
In addition to a manual setting, the rate can be control-
led by an external clock - eg. VCO, LFO or MIDI clock).
The 808 Source aims to re-create the sort of multi-
oscillator array that was used in Roland’s TR-808
and 606 drum machines as the basis of the sound of
the hi-hat, cymbals and cowbell. The cowbell mix
uses two oscillators, and the cymbals mix six.
