This is one of Eurorack's most underrated random modules!
The ADDAC501 does random CV generation and outputs it through four 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 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.
. Four independent CV outputs.
. Four 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.
. External Clock On / Off - allows to sync to an external clock.
. Standard / Brownian Time - selects the type of random algorithm used for the clock timing.
