The U6 Trio is a triple switch expander designed to extend the controls of the Unity6 midi controller/loop switcher. Each of the three footswitches features both short‑press and long‑press actions, offering six programmable functions. It can be daisy‑chained—up to two U6 Trios per UniPort (for a maximum of 12 extra switches)—and allows both global control across all banks and individual bank overrides. No external power is required; it communicates via TRS connection only.
