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 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.

The frequency of the VCO is determined by the position of the range switch and tune controller and the control voltages at the CV inputs. Thus, the VCO provides the possibility of frequency modulation. You can set the footage (octave of the fundamental) with the selector switch. The Tune control is used to fine tune the VCO frequency.

In the pulse wave the pulse width can be adjusted manually or by voltage control or modulated (PWM).
