Adding inputs to the Benjolin is easy. Each input that CAN receive a CV signal or audio already has a mixer built in. Adding more inputs is simply a matter of adding a jack and a resistor (and a capacitor in the case of audio inputs). It’s also a good idea to add input level potentiometers. Just follow the schematic and you'll be in good shape.
