M-Audio Midisport Uno USB MIDI Interface

Overview

The M-Audio Midisport Uno USB MIDI Interface has been quietly doing its job since 2006 — and that kind of staying power says a lot in a market where gear comes and goes fast. This is a single-in/single-out MIDI bridge, which is exactly what most solo musicians need when connecting a keyboard or controller to a computer. It draws power directly from your USB port, works on both Windows and macOS, and requires no external adapter. Don't expect multiple ports or advanced routing options. What you get instead is a focused, no-frills workhorse that handles the one job it was built for, reliably.

Features & Benefits

One of the most practical things about the Midisport Uno is that it pulls power straight from your USB port — no wall adapter, no hunting for an outlet. The built-in USB cable is a small but genuinely useful touch; one fewer loose cable rattling around in your bag. At under four ounces, this little interface is light enough to forget about until you need it on stage or in the studio. It supports 16 MIDI channels in each direction, covering the full range of standard DAW workflows — picture a synth keyboard plugged into Ableton or Logic without any fuss. You can also stack extra units across available USB ports if your rig eventually grows.

Best For

This MIDI adapter is an obvious fit for anyone just starting out with MIDI — someone who bought their first keyboard and wants to get it talking to GarageBand or FL Studio without overcomplicating things. Home studio producers who only need a single keyboard or controller connected at a time will find everything they need here. It also works well for gigging musicians who want something lightweight and reliable to throw in a backpack. Teachers setting up simple MIDI stations for students will appreciate how little setup it demands. And if your old interface finally gave out, this little interface is a dependable replacement that won't require much of an adjustment period.

User Feedback

Across more than 700 ratings, this MIDI adapter holds a solid 4.3-star average — a respectable score for something that has been on the market for nearly two decades. Most buyers highlight ease of setup and consistent day-to-day reliability as its strongest points. Where things get more nuanced is with drivers: a portion of users have reported hiccups after major OS updates, particularly on newer macOS versions, though the majority get it running without incident. A few buyers also wished the built-in cable were a bit longer for certain desk arrangements. On durability, long-term owners are split — many report years of trouble-free use, while others note the rubber body showing wear earlier than expected.
