Nin is easily connected to the Zadar via the expansion header on the back of the modules.
Per channel A-D you get one additional CV-input, called ASGN2. Same as with ASGN on the Zadar, you can freely assign one (of ten available) parameters to these inputs. This is done via the ASGN menu on the Zadar, where you can also precisely edit the parameter range.
On the top of the Nin module you find four buttons that allow you to manually trigger the Zadar envelopes.
