An interconnection cord that is intended to make a connection between an input and an output of a patch bay or on the panel of a modular synthesizer or semi-modular. Typically these cords are shorter (1 to 3 feet in length) and somewhat less sturdily constructed than cords used to, for instance, connect instruments to a mixer. Because some patches may involved the use of many patch cords, some manufacturers offer sets of patch cords with different colors of insulation, to make visual distinction easier.
