CV Merger provides eight channels of merging in a 1U device. Each merger has four inputs. In order to do this kind of merging with a Spider merger, it would take eight devices and 4U of rack space. CV Merger is perfect for the Polymodular System, which supports eight voices. And it has a cool Polymodular System logo. Own Reason? CV Merger is available for free in the Propellerhead Shop
There are level controls on the front for mixing the four inputs. It also has two voltage-controlled amplifiers for controlling the level of CV signals. The front panel Amp controls act as additional level controls for the VCAs.
