This module provides basic functions for transforming and translating voltages and synthesizer signals. It's able to attenuate/amplify and add positive or negative offsets to voltages.
The module has two identical channels and works with both +/-12V or +/-15V systems without modification. It can be used to turn a bipolar signals into a unipolar signals or vice-versa and I've found it especially useful in patches where a VCA's output is fed back into it's voltage control input.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.

Unfinished eurorack
panels are available for this project, they are 6HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
