CME MIDI Thru5 WC - Premium 1-to-5 MIDI Thru - Reliable Low-Latency

In this review the CME MIDI Thru5 WC proves itself as a no-nonsense, purpose-built MIDI splitter for musicians and engineers who need reliable distribution of MIDI data. It excels when you must feed five devices from one MIDI source without worrying about dropped messages or timing issues. The unit's high-speed optocoupler design and USB-C 5V bus power deliver accurate signal isolation and near-zero latency, making it a sensible addition for studio rigs, live setups or pedalboard integrations where timing and integrity of MIDI data matter most.

Key Features

• 1-in-5-out: Splits a single MIDI input to five isolated outputs so multiple sound modules, synths or controllers can receive the same stream simultaneously.
• High-speed optocoupler: Ensures isolated transmission to prevent ground loops and maintains error-free synchronization across devices.
• Close to zero latency: Designed for professional use so MIDI timing, including clock and timecode, remains tight and jitter-free.
• Compact, reinforced housing: Lightweight metal case with hexagonal reinforcement makes it durable and easy to tuck into pedalboards or racks.
• USB-C power: Runs from any standard 5V USB source for flexible powering on stage or in the studio without relying on MIDI bus power.

Who It's For

The CME MIDI Thru5 WC is aimed at performers, studio engineers and electronic musicians who need to distribute one MIDI source to several devices while preserving timing and message integrity. It is particularly useful for setups where multiple sound modules or hardware synths must be locked to a single controller or sequencer.

Those who should look elsewhere include users who need USB-MIDI routing, DAW-integrated multi-port interfaces with audio I/O, or programmable routable merge/split features; this product is a dedicated, wired 5-way thru and not a full-featured USB audio/MIDI hub.

Pros & Cons

Pros

• Reliable distribution with no reported data errors or signal dropout, so connected devices stay in sync.
• Solid build quality and compact footprint, suitable for pedalboards and tight studio spaces.
• Easy to set up and value-oriented according to user feedback, delivering pro-level performance without complexity.
• Opto isolation prevents ground loop issues between gear when powered via USB-C.

Cons

• Does not supply or accept power over MIDI ports, so a USB-C 5V source is required for operation.
• Not a multi-port USB MIDI interface, so users needing host-style USB routing should consider other devices.

Frequently Asked Questions

Can the Thru5 be powered through a MIDI input?
The device cannot be powered via MIDI IN or supply power through MIDI OUT; it requires a 5V USB-C power source.

Will it pass all MIDI message types?
Yes, it supports all standard MIDI messages including notes, controllers, clock, sysex, timecode and MPE.

Is it suitable for pedalboard use?
Yes, the compact reinforced housing and lightweight design make it easy to place on or under a pedalboard.
