# Roland UM-ONE Mk2 USB MIDI Interface

Roland UM-ONE Mk2 USB MIDI Interface

The Roland UM-ONE Mk2 USB MIDI Interface was $46.99 when we checked it on 2026-09-14. It has not moved from that price across 4 checks since 2026-08-18.

## Overview

From the pioneer of the PC MIDI interface, Roland introduces the new UM-ONE mk2. A 1-in/1-out USB bus powered MIDI interface with high-performance FPT processing for low latency and tighter clock timing. Compatible with Mac, PC and iPad via Apple Camera Connection Kit, the super compact UM-ONE mk2 is an affordable, reliable, easy-to-use MIDI interface.

## Why we picked it

Best for: One synth or keyboard that just needs to reach a computer.

A 1 in / 1 out USB MIDI cable interface with Roland's FPT processing for low latency and tight clock timing.

**What we like**
- 1 in / 1 out with the USB and MIDI cables built into the unit
- FPT processing keeps latency low and clock timing tight
- Works with Mac, Windows and iPad via Apple's Camera Connection Kit
- USB bus powered, no separate adapter to carry

**Watch outs**
- Only one MIDI in and one MIDI out, no merge or thru
- No routing or filtering, it only passes MIDI straight through
- Becomes a bottleneck the moment a second device joins the rig
