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.

Module A-118 is a noise and random voltage generator. It produces the following signals: white noise, coloured noise, and random voltage. White and coloured noise can be used as audio signals, and also (in conjunction with an S&H module) as a control voltage. The resulting random voltage is mainly used as a control voltage, especially because of its low frequency content.

There are knobs to control the rate of change and amplitude of the random voltage, and two LEDs indicate the state of the voltage.

Module A-118 is a noise and random voltage generator. The A-118 generates the signals white noise, coloured noise, and random voltage. Whilst white and coloured noise can be used both as an audio signal and as a control voltage (in conjunction with an S / H module), the generated random voltage is predominantly used as a control voltage because of the emphasis on the low frequency. The A-118 offers you the possibility to individually adjust the sound colours of the coloured noise by setting the red portion (low frequencies) and the blue portion (high frequencies) separately.

The course of the random voltage, which the rate of change and amplitude you can adjust, is indicated by two LEDs.
