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.

BBDs are used to delay audio signals before digital delays are able to deactivate the BBD-generated effects. BBDs have some very unique advantages (or disadvantages - depending on the point of view) over their digital counterparts, a result of some of the special properties inherent in BBDs. BBD circuits can be treated as a chain of Sample & Hold units (S H), which pass on their voltages to the next S&H in the chain at each clock pulse.

The sound produced by the A-188-1 module is very special indeed. Typical applications include: Flanger, Chorus, Analog Delay or Karplus / Strong Synthesis. As the A-188-1 has a lot of unique features (voltage controlled clock rate / delay time with extreme range, polarity switches for CV inputs, feedback and BBD Out/Mix, clock and CV high speed VCO output, BBD clock input, feedback insert, feedback to self-oscillation), it's not at all unfeasible to discover many unusual applications, e.g., delay controlled by ADSR, envelope, random or sequencer with positive or negative effect.
