UM-3EX: USB MIDI Interface
Features
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.
- 3-in/3-out MIDI ports (female)
- Out or Thru selectable switches built-in
- USB hub built in, and up to 3-unit cascade connection
- Control up to 48 channels of MIDI equipment
- Rackmountable in a RAF-70
- Fast and stable MIDI data transmission realized by FTP
- USB bus power (AC adaptor not required)
EDIROL designs its USB devices in accordance with USB specifications and has passed all compatibility tests, which are continuously held and organized by USB Implementers Forum (USB-IF).
