This Module is currently available.
This module replicates the Oscillator CV mixer from the Moog CP3 control panel as an 8HP wide separate module.
There are four CV inputs and internal patching for driving Behringer 921A or AMSynths AM901 oscillator controller modules. The module is designed to reduce the need for patch cables and to replicate the CV internal bus structure of the original Moog Modulars.
The module AM996 is supplied with PCB Daughter Boards that attach to the rear of the 921A and 921B and a cable that interlinks them with the AM996. The AM901A and AM 901B do not require daughter boards and are "plug and play".

These merchants probably sell this module. Huh?
