This Module is currently available.
Quad Attenuator/Inverter, Splitter, and Offset Generator
Scale your audio or CV sources and route them to various destinations with this versatile utility. It consists of four identical unity gain amplifiers. Each amplifier can multiply an incoming signal by values ranging from 0 to 1 (for attenuation) or from 0 to -1 (for inverting attenuation). The input of each channel is normalled to the input of the next channel, allowing for easy signal routing from one input to the subsequent ones.
The first channel is normalled to 10V, enabling the module to function as an offset generator when no input is connected.
These merchants probably sell this module. Huh?
