Wiring all of your devices accessible in the signal line can be daunting if you don’t use patch bays. Whenever a larger number of devices are present patch bays help simplify. Wire every device and connection to your patch bay, IN’s and OUT’s. Using small patch cables you choose which effect, synth or keyboard to run. Here are some useful images to understand the different arrangements a patch bay may be configured. If you wondering which one to get, buy a full TRS patch bay with selectable routing on the front.
