MIDI THRU-6 Pro Box MIDI Splitter + USB MIDI Output - Reliable MIDI

Our review of the MIDI THRU-6 Pro Box finds it a compact, practical solution for musicians and studio technicians who need to expand a single MIDI source to multiple destinations. The unit's main appeal is straightforward: it converts one MIDI input into six outputs including traditional DIN outs, a MIDI THRU and a USB MIDI port, so users can feed multiple synths, modules or a DAW simultaneously without a computer. It is presented as a stand-alone device that can also communicate over USB, making it useful for both live rigs and small studio setups.

Key Features

• Multi-output expansion: Extends a single MIDI IN to five MIDI OUT ports plus a MIDI THRU so several instruments can receive the same performance data.
• USB MIDI support: Provides a USB MIDI connection that allows a computer or USB host to send and receive MIDI alongside the DIN outputs.
• Flexible routing: Accepts MIDI from either the DIN input or USB host and routes it to the five outputs and thru port for versatile setup options.
• Message filtering: MIDI OUT1 through OUT5 offer configurable message filtering so users can block or allow specific MIDI message types to individual outputs.
• Standalone operation: Can operate without being connected to a computer, allowing it to function reliably in live performance or hardware-only studios.

Who It's For

The MIDI THRU-6 Pro Box is best for keyboardists, synth enthusiasts, and small studio owners who need a dependable hardware solution to duplicate and distribute one MIDI source across several devices. It suits rigs where a single controller must drive multiple sound modules or when a backing device must be mirrored to several destinations.

It is less appropriate for users who need deep software integration or advanced routing that is managed by a dedicated MIDI patchbay/sequencer; those users may prefer a unit with more extensive computer-based configuration or pattern routing capabilities.

Pros & Cons

Pros

• Provides six-way distribution including DIN MIDI and a USB MIDI port for flexible connectivity.
• Message filtering on individual outputs lets users tailor what each connected device receives.
• Works standalone so it is practical for live setups without a laptop.

Cons

• Configuration details are limited in the product brief, so deep routing or advanced setup may require a manual or trial to fully exploit.
