Best 10 Compact Midi Interfaces Picks for 2026

Best All-in-One Pick – Arturia MiniFuse 1

If you want compact MIDI interfaces that also handle microphones, instruments, and headphones, the Arturia MiniFuse 1 is a versatile choice. It combines 5-pin MIDI I/O with a mic/line/instrument input, balanced outputs, phantom power, loopback, and a USB hub in a small enclosure.

Best For: Home recording, mobile production, vocalists, guitarists, and beginners who want bundled software.

Pros:

• Includes 5-pin MIDI input and output alongside audio connections.
• Supports recording at up to 192 kHz and includes 48V phantom power.
• Loopback makes it useful for capturing voiceovers with in-app or in-game audio.
• Includes Ableton Live Lite, Analog Lab Intro, effects, guitar software, Auto-Tune Unlimited, and a Splice Creator Plan.

Cons:

• Its single-channel design is less suited to recording multiple sources at once.
• The USB hub is rated for 250mA, limiting what it can power.

The MiniFuse 1 stands out when MIDI connectivity is only part of your setup. Its compact format, broad software bundle, and unusually long five-year warranty make it a strong starter interface for flexible recording.

Best MIDI Splitter – CME MIDI Thru5 WC

The CME MIDI Thru5 WC is a focused option among compact MIDI interfaces for setups that need to send one MIDI signal to several devices. Its 1-in-5-out design uses standard 5-pin MIDI connections and USB-C power, making it practical for crowded studios, pedalboards, and live rigs.

Best For: Splitting one MIDI source across multiple synthesizers, drum machines, or other standard MIDI devices.

Pros:

• Distributes one MIDI input to five MIDI outputs.
• Supports all MIDI channels and messages, including clock, SysEx, timecode, and MPE.
• High-speed optocoupling is designed to prevent data errors, signal dropouts, and ground loops.
• Compact reinforced housing and USB-C power suit portable setups.

Cons:

• It is a MIDI thru box, not an audio interface or computer USB MIDI interface.
• The USB port supplies power only.
• Its 1-in-5-out layout does not provide MIDI merging or multiple MIDI inputs.

Choose the MIDI Thru5 WC when reliable signal distribution matters more than recording features. It is a specialized, low-latency routing tool rather than a general-purpose interface.

Best Compact Audio Interface – Focusrite Scarlett Solo 3rd Gen

For shoppers comparing compact MIDI interfaces with audio recording needs, the Focusrite Scarlett Solo 3rd Gen is a streamlined audio-first option. It provides an XLR mic preamp, a Hi-Z instrument input, two balanced outputs, headphone monitoring, and USB-C connectivity for computer and iPad-based workflows.

Best For: Solo vocalists, guitarists, podcasters, and producers who prioritize high-quality audio recording over built-in 5-pin MIDI.

Pros:

• Records at up to 24-bit/192 kHz with high-performance converters.
• Air mode can add clarity to acoustic instruments and vocals.
• Gain Halos help monitor input levels and avoid clipping.
• Includes Pro Tools Intro+, Ableton Live Lite, Cubase LE, and Hitmaker Expansion software.

Cons:

• The supplied notes do not list built-in 5-pin MIDI connections.
• Its single mic preamp limits simultaneous microphone recording.
• It offers two instrument inputs but one XLR mic preamp, so input flexibility is limited.

The Scarlett Solo is a sensible pick for a compact recording desk when your main sources are one microphone and one guitar or bass. It delivers useful monitoring and recording features, but MIDI users will need separate MIDI hardware.

Best Routing Features – CME U6MIDI Pro

The CME U6MIDI Pro is one of the most capable compact MIDI interfaces for complex routing. Its 3-in-3-out design works with computers and mobile devices over USB-C, while standalone routing, merging, splitting, filtering, and mapping make it useful in both studio and live MIDI systems.

Best For: Multi-device MIDI rigs that need flexible routing, filtering, merging, or standalone operation.

Pros:

• Provides three MIDI inputs and three MIDI outputs through standard 5-pin DIN connections.
• Works with macOS, iOS, Windows, Android, Linux, and Chrome OS.
• Standalone router supports split, thru, merge, filtering, and mapping configurations.
• Supports MIDI notes, controllers, clock, SysEx, timecode, and MPE with near-zero latency and no jitter.

Cons:

• It handles MIDI only and does not provide audio inputs or outputs.
• Advanced configuration requires the UxMIDI Tools software.
• Its expanded routing features may be more than a simple one-device MIDI setup needs.

The U6MIDI Pro is the strongest choice here for users who need more than basic USB-to-MIDI conversion. Its small footprint hides a flexible routing platform, though audio recording requires a separate interface.

Best Compact Recording Interface – Focusrite Scarlett 2i2 4th Gen

The Focusrite Scarlett 2i2 4th Gen is a practical choice for musicians seeking compact midi interfaces and a straightforward USB-C recording setup. Its two mic preamps, Hi-Z instrument inputs, and 24-bit/192kHz support suit vocals, guitars, and basic stereo recording.

How We Picked the Best Compact Midi Interfaces

We evaluated these Compact Midi Interfaces by focusing on the connections and routing features that matter in real studio and performance workflows. The lineup includes straightforward USB audio/MIDI interfaces, dedicated MIDI routers, thru boxes, and USB host devices for connecting MIDI hardware without a traditional computer.

Our comparison considers port count, input and output flexibility, USB compatibility, standalone operation, portability, expansion potential, and the type of setup each model suits best. We also separated basic MIDI distribution from more advanced routing and host functions, since these products are not interchangeable.

Quick Comparison

• Simple computer recording: Choose an audio interface such as the Arturia MiniFuse 1, MiniFuse 2, or Focusrite Scarlett Solo.
• Recording with multiple inputs: The Focusrite Scarlett 2i2 offers more flexible audio connectivity than single-input models.
• Basic MIDI splitting: A CME MIDI Thru5 or six-output MIDI Thru box can distribute one MIDI signal to several devices.
• Advanced MIDI routing: The CME U6MIDI Pro is designed for more complex multi-device connections.
• USB host operation: CME H2MIDI Pro, H4MIDI WC, and H12MIDI Pro models can help connect USB MIDI gear to traditional MIDI setups without relying on a computer.

Key Buying Factors for Compact Midi Interfaces

Connection Type and Port Layout

First, identify whether you need USB MIDI, five-pin DIN MIDI, audio inputs, or a combination. Check the number of inputs and outputs carefully: a thru box duplicates one incoming MIDI signal, while a multi-port interface can support two-way communication between several devices.

Routing and Expansion

Basic setups may only need reliable signal distribution. More involved rigs benefit from configurable routing, multiple independent ports, filtering, and the ability to expand later. Leave spare connections if you expect to add a synthesizer, drum machine, controller, or effects processor.

USB Host Compatibility

USB host interfaces are useful when you want to connect USB MIDI controllers or instruments directly to MIDI hardware. Confirm the required cable type and power arrangement, especially if your controller draws power over USB.

Portability and Power

Compact dimensions are valuable for mobile production and live performance, but power requirements still matter. A bus-powered unit is convenient with a computer, while standalone gear may require USB power or an external adapter.

Who Should Buy Which Compact Midi Interfaces?

Choose the Arturia MiniFuse 1 or Focusrite Scarlett Solo if you want a small computer-based recording interface with MIDI support and minimal desk space. Choose the Arturia MiniFuse 2 or Scarlett 2i2 if you need additional audio input flexibility for stereo sources or two microphones.

Choose a CME MIDI Thru5 or MIDI Thru 6 Box for simple one-to-many MIDI distribution. Choose the CME U6MIDI Pro if your setup needs multiple ports and more involved routing. Choose a CME H2MIDI Pro, H4MIDI WC, or H12MIDI Pro when USB host functionality is the priority and you want to connect USB MIDI devices to hardware without keeping a computer in the chain.
