H4MIDI WC

CME H4MIDI WC is an advanced USB Host MIDI interface with built-in MIDI router, filter, and mapper, plus optional WIDI Bluetooth MIDI expansion. It features 2-in/2-out standard 5-pin DIN MIDI ports, supporting full bidirectional communication, and expands via USB-A to connect up to 8 USB MIDI devices via a standard USB hub. The USB-C port provides 4-in/4-out virtual MIDI ports to your computer or mobile device. Future-proof, ultra-accurate, and pedalboard-ready, it’s the ultimate tool for seamless, flexible MIDI integration.

The CME H4MIDI WC redefines MIDI connectivity with a groundbreaking blend of USB host and client capabilities in one compact device. It’s the most accessible interface to offer 8-in/8-out USB-A host ports for direct connection of multiple class-compliant USB MIDI devices without needing a computer, while simultaneously supporting 4-in/4-out USB-C client virtual MIDI ports for full computer and mobile integration.

It introduces advanced standalone MIDI routing, filtering, and mapping — all configurable via free cross-platform software — allowing complete customization without requiring a computer on stage or in the studio.

The optional WIDI Core expansion adds premium Bluetooth MIDI with ultra-low 3ms latency, smart auto-pairing, and group networking (split/merge), unlocking wireless setups that were previously complex or unstable.

Its dual power options (USB power bank or 9V DC pedal power), pedalboard-friendly design, and smart LED indicators further show how CME focused on real-world, musician-centric innovation.

In short, it’s a future-proof, modular platform that evolves with your setup — not just another MIDI interface.

The most inspiring use of the CME H4MIDI WC is how it liberates musicians, producers, and performers from traditional MIDI limitations — creating fully computer-free, modular setups that were once complicated or impossible.

Imagine this:
A live performer connects multiple USB MIDI devices (keyboard, pad controller, MIDI footswitch, synth module) directly to the H4MIDI WC, without a laptop, using only a small USB hub.

They customize their entire routing and filtering with presets — instantly switching setups between songs.

With the optional WIDI Core, they add Bluetooth MIDI to sync seamlessly with wireless devices like an iPad running synths or sequencers.

All powered by a small power bank or pedal power supply — slim enough to fit neatly on a pedalboard.

It transforms a chaotic stage setup into an elegant, portable, wireless-capable rig — giving artists freedom, flexibility, and total creative control, anywhere.

It’s not just a MIDI interface. It’s a MIDI liberation tool.
