Or you could just get a volt meter out and a little wire and test the voltage before plugging it in. I'd advise that regardless in any and all situations dealing with expensive musical equipment.
A very clear explanation. In answer to "why 4 grounds?": Ribbon cables are not ideal for power distributiion due to the resistance of the thin wires (and connector contacts). Too reduce volts drops across the resistive cable and contacts due to current flow there are 4 paths in parallel. Analogue Systems use 4 contacts for each power rail & ground. Doepfer use 2 for the power rails but 6 for grounds. A lower resistance ground path helps to reduce ground loop effects.

Doepfer is pronounced like derpfa.

why does the connector have so many wires? why is there GND for like 4 times? that sucks for DIY projects if you want to make them very compatible...

The ribbon carries ground, 5v, 12v, CV bus and gate bus signals.

Too many wires for me, I'd definitely blow it up.
