Doepfer A-189-1 Eurorack VC Bit Modifier Module

Module A-189-1 is a voltage controlled bit modifier. It offers several voltage controlled algorithmic functions like voltage controlled bit crunching, bit shifting (with/without carry over), bit exchange, rectifying, absolute value and calculating operations like addition, subtraction, multiplication or division.

The module has two control units both with manual control and CV input with attenuator:

one for the algorithmic function according to the selected mode (e.g. number of shifted bits): BC and BC CV

and one for the sampling rate (SR and SR CV).

The signal input is equipped with an attenuator. As the module is DC coupled even control voltages can be processed.
