Module A-117 (DNG) is a combination module, including a digital noise generator and an 808 source. The digital noise generator uses random sequences of square waves, (18-band, with multiple slewed feedback 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 controlled by an external clock – eg. VCO, LFO or MIDI clock). The 808 Source aims to re-create the sort of multioscillator 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.
