The UM-3EX is the most innovative mid-sized MIDI interface on the market. The expandable design of the UM-3EX makes it the ideal MIDI interface for the small studio, but allows you to daisy-chain up to three units together for a total of nine MIDI inputs and outputs. The UM-3EX can be mounted into the RAF-70, a rackmount kit, making for a clean, expandable studio installation. The UM-3EX allows you to select between MIDI Out and MIDI Thru for each output port. The UM-3EX uses FPT (Fast Processing Technology) to ensure low-latency, low-jitter MIDI transmission, even with three devices daisy-chained together
