Best MIDI Distribution Hub – MIDI Thru5 WC
CME MIDI Thru5 WC 1-in-5-out MIDI Thru | 5-pin DIN, High-speed, Optional Bluetooth
Check Price On AmazonThe CME MIDI Thru5 WC is a compact MIDI interface for expanding one MIDI source to as many as five connected devices. Its small, reinforced housing is designed for crowded studios, stage rigs, travel setups, and pedalboards, while USB-C power keeps the unit easy to integrate.
Best For: Musicians who need to distribute one MIDI signal reliably to multiple hardware devices.
Pros:
- One MIDI input feeds five standard 5-pin MIDI outputs.
- Supports all MIDI channels and messages, including clock, sysex, timecode, and MPE.
- High-speed optocoupling is designed to minimize errors, signal dropout, ground loops, and jitter.
- Compact, lightweight housing works well in space-constrained setups.
Cons:
- It is a MIDI Thru box, not an audio interface or USB MIDI data interface.
- The USB-C port is for power only.
- Requires standard 5-pin MIDI cables and an external 5V USB power source.
The MIDI Thru5 WC is a specialized option rather than a general-purpose compact MIDI interface. Choose it when dependable one-to-five MIDI routing is the priority; its focused design is less appropriate if you also need recording inputs, outputs, or computer MIDI connectivity.
Best for Basic Recording – Scarlett Solo 3rd Gen
The Focusrite Scarlett Solo 3rd Gen is a compact audio interface for recording a microphone or instrument, with a straightforward setup that also suits MIDI-based computer studios when paired with separate MIDI hardware. It offers a mic preamp with Air mode, a Hi-Z instrument input, headphone monitoring, balanced outputs, and USB-C connectivity.

How We Picked the Best Compact Midi Interfaces
We selected these Compact Midi Interfaces based on connection options, portability, compatibility, ease of use, and usefulness in real-world setups. The lineup includes dedicated MIDI splitters, multi-port MIDI interfaces, USB host devices, compact controllers, and audio interfaces with MIDI functionality.
Because MIDI systems vary widely, there is no single best design for everyone. A small interface with one input and several outputs may be ideal for distributing a controller signal, while a USB host interface is better for connecting class-compliant USB MIDI gear to traditional DIN hardware. We also considered whether each product solves a clear connectivity problem without taking up unnecessary desk space.
Quick Comparison
| Best For | Look For |
|---|---|
| Basic MIDI splitting | One MIDI input and multiple outputs |
| Computer-based setups | USB MIDI support and dependable driver compatibility |
| Hardware-focused studios | Multiple DIN inputs and outputs |
| USB MIDI instruments without a computer | USB host functionality |
| Compact hybrid recording rigs | Audio inputs plus MIDI connectivity |
| Live sequencing and performance | Built-in pads, sequencing, and hands-on controls |
Key Buying Factors for Compact Midi Interfaces
Ports and Signal Direction
Start by counting the MIDI inputs and outputs your setup needs now, then allow room for one or two additions. An input receives data from a controller or instrument; an output sends data to another device. A MIDI Thru output copies incoming data, which is useful for sending one controller signal to several destinations.
USB Host Versus USB MIDI
A standard USB MIDI interface generally connects MIDI equipment to a computer or compatible host. A USB host interface can connect USB MIDI devices directly to hardware that uses traditional MIDI connections, often without a computer. Confirm the exact host and port requirements before buying, since USB-A, USB-B, USB-C, and DIN connections are not interchangeable without the right cables or adapters.
Audio Needs and Portability
If you also record microphones, instruments, or line-level sources, an audio interface with MIDI may be more practical than a dedicated MIDI box. Check input type, phantom power, monitoring, and headphone features. For mobile rigs, prioritize bus power, a compact enclosure, sturdy connectors, and a control layout that is easy to use under pressure.
Routing, Timing, and Compatibility
Dedicated hardware routing can reduce cable clutter and make a setup easier to operate. Look for reliable timing, clear status indicators, and any required editor or firmware support. Verify operating-system compatibility and whether the device needs external power, especially when connecting several MIDI instruments.
Who Should Buy Which Compact Midi Interfaces?
Choose a simple MIDI Thru box if you only need to duplicate one incoming signal across multiple instruments. Select a multi-port MIDI interface if you need independent two-way communication between a computer and several hardware devices. USB host models are the better choice for integrating USB-only controllers or instruments with DIN-based equipment.
Musicians who need recording and MIDI in one compact unit should consider an audio/MIDI interface. Producers who want hands-on sequencing and performance control may prefer a compact MIDI controller with built-in sequencing functions. Before ordering, map every device in your setup, identify whether each connection is USB or DIN, and check the required power and routing options.
