Passive mult

The passive mult is probably the easiest module to possibly build, all you need is some jacks, some wire, and a soldering iron. This module allows you to split a signal to be sent to multiple destinations. Passive mults are not suitable for V/octave CV control, because the voltage may drop when split, due to varying impedance in the destinations.

Circuit
Simply wire all jack tips together, and all barrels together. More complex designs can use switched jacks to split multiples into smaller sub-groups.
