I have a question.. So, I have a Doepfer a-100 powered case and a small collection of 15 or so different modules. With all these pins on the back of each module precisely connected to the rails are there any timing or sync or control voltage signals being shared or tied in to the rack.. It's cool if there isn't, though it seems as if there's more pin connections then just power .. -Thanks - Jupitor


THere are dedicated lines for one CV and one gate/trigger signal in a Doepfer compatible modular system. However, these are used rarely. See:
