M-Audio Midisport Uno MIDI Interface - Compact 1-in/1-out USB

In this review of the M-Audio Midisport Uno, the bottom line is simple: it is a no-frills, reliable 1-in/1-out MIDI interface for musicians and producers who need straightforward connectivity between a computer and a single MIDI device. The Uno is ideal for hobbyists, small home studios and performers who value portability and a plug-and-play experience; its bus-powered USB design and built-in cables make setup quick and uncomplicated, and the unit supports the full 16 MIDI channels per port expected from standard MIDI hardware.

Key Features

• 1-in/1-out operation: Provides one MIDI input and one MIDI output port to connect a single keyboard, module or controller to your computer without extra adapters.
• 16 MIDI channels: Each port supports 16 discrete channels so you can route multiple MIDI signals between your DAW and external gear as needed.
• USB bus powered: Draws power from the computer USB port for true portability and eliminates the need for an external power supply.
• Built-in cables: Ships with an integrated USB cable and a MIDI cable so you can get up and running straight out of the box.
• Compact footprint: Small size with rubberised non-slip feet keeps the unit unobtrusive on a desktop and stable during use.
• Universal compatibility: Designed to work with Mac and PC operating systems for broad cross-platform use.

Who It's For

The Uno suits bedroom producers, live performers with minimal MIDI routing needs, and anyone who needs a dependable, portable MIDI-USB interface for one keyboard or module. It is particularly useful when simplicity and fast setup are priorities, such as quick rehearsals, mobile rigs and basic studio tasks.

Those who need multiple simultaneous hardware connections, advanced routing, or integrated MIDI DIN thru/merging should look elsewhere; the Uno is intentionally pared down to a single input and output and does not replace multi-port interfaces for complex setups.

Pros & Cons

Pros

• Very easy installation with USB bus power and included cables for immediate use.
• Solid build quality and compact design that fits unobtrusively on a desktop.
• Supports full 16 channels per port, enabling standard multi-channel MIDI workflows.
• Good value for users who only need one MIDI in and out.

Cons

• Limited to a single MIDI in and out, so not suitable for multi-device setups without a MIDI merger or router.
• Compatibility is generally broad but some users report issues on certain Windows versions, so driver or OS checks may be necessary.
