This module exposes our internal CV-8 bus to the outside world. Handy for use with the 1515 AD/AR Expander so you can get the envelopes directly from the 1515.
It has two CV-8 plugs, thus allowing cascading of the 1510 Octal VCA, and comes with the necessary additional CV-8 cable.
These merchants probably sell this module. Huh?
