The Doepfer A-117 Digital Noise / 808 Sound Source is the sound engine behind the legendary drum machines hihat cymbal and cowbell sounds. Adjust the tone of the module with your system's envelopes and VCAs. You can even clock the randomness to get away from the standard 808 (or 606) sounds.


Doepfer A-117 Digital Noise / 808 Sound Source is a combination module, including a digital noise generator and an 808 source. The digital noise generator uses random sequences of square waves (18 step shift register with multiple feedback), whose rate can go from random clicks to noise.

The colour of the noise is very different from the analog noise produced by the A-118. The frequency range of the internal clock oscillator is about 100Hz - 100kHz. In addition to a manual setting, the rate can be controlled by an external clock - eg. VCO, high speed VCO of A-188-1/2, 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. For more detailed information please look at the English user's manual
