The ADDAC501 does random CV generation and outputs it through three independent channels. You can control the desired range of voltages and time frequency at which new values are generated.
It can also be triggered by an external CV source and the output voltages can be either free or quantized (if you prefer to have a standard C Major Pentatonic scale).
Finally you can choose between pure randomness or a brownian distribution, for both the voltage and time intervals.
Maximum and minimum voltage
Maximum and minimum time interval
Three independent outputs
Standard or Brownian distributions
External clock input
. Four variable settings: Voltage Maximum, Voltage Minimum, Frequency Maximum and Frequency Minimum, controlled either manually through the front panel knobs or externally from a CV input.
. Three independent CV outputs.
. Three SPDT switches located at the bottom of the panel.
. Standard / Brownian - selects the type of random algorithm used.
. Quantization On / Off - allows to quantize the zero to five volts range to a Major Pentatonic scale using Moog’s 1v per octave standard.
. Standard / Brownian Time - selects the type of random algorithm used for the clock timing.

Interactive Users Guide
This guide features all the functions of the real hardware module plus a graphical display that resembles an oscilloscope and a very simple sound engine as if the module output was plugged straight into the CV input of a VCO.
The audiovisual experience of using this application makes it a very effective demonstration of the module’s operation.
