CME today announces the start of production for the H12MIDI Pro, a compact standalone MIDI hub designed to simplify complex hardware and hybrid MIDI setups. The device combines USB Host connectivity, TRS MIDI I/O, and advanced routing capabilities in a portable aluminum enclosure.
The H12MIDI Pro features six USB-C Host ports supporting up to 16-in / 16-out virtual MIDI, allowing class-compliant USB MIDI devices such as keyboards, controllers, drum machines, and pedals to connect directly without a computer.
In addition, six TRS MIDI inputs and outputs (3.5 mm A/B) provide integration with a wide range of hardware synthesizers, modules, and MIDI equipment.
A dedicated USB-C Client port adds computer connectivity with 8-in / 8-out virtual MIDI, compatible with macOS, Windows, iOS, Android, Linux, and ChromeOS.
Advanced MIDI routing, filtering, mapping, and preset management are handled through CME’s HxMIDI Tools software, allowing creators to configure MIDI thru, split, merge, and message processing. All configurations are stored internally for reliable standalone operation.
The H12MIDI Pro also offers dual power options via USB-C (5V) or 9V DC, making it suitable for both studio setups and pedalboard installations.
With its compact footprint and flexible connectivity, the H12MIDI Pro provides a centralized MIDI solution for musicians, producers, and live performers working with modern hardware and hybrid environments.

CME CEO Mr. Zhao Yitian: “Throughout the development process, CME worked closely with people who actively rely on MIDI technology in real-world studio and live environments. This collaborative approach ensures that the final product reflects practical needs while staying true to CME’s design philosophy: powerful MIDI tools that remain compact, flexible, and accessible without paying for features you don’t need”.
Community-Driven Development
The H12MIDI Pro was developed together with the Community of MIDI Enthusiasts through CME’s Crowd Creation program. The design builds on feedback from musicians and creators actively using the H4MIDI WC and H2MIDI Pro, who requested a more compact and portable USB Host MIDI interface for modern hardware setups.
One of the key requests from the community was the adoption of 3.5 mm TRS MIDI ports instead of traditional 5-pin DIN connectors. This allowed CME to significantly reduce the size of the device while maintaining full MIDI functionality. The H12 automatically detects TRS Type A or Type B on input, while output ports can be configured for Type A or B via software.
The compact TRS MIDI design enabled CME to create a device as small as a guitar pedal and as light as a modern smartphone. For compatibility with traditional 5-pin DIN equipment, CME offers specially designed low-profile straight TRS-to-DIN MIDI cables that preserve the device’s compact form factor.
Another design improvement influenced by community feedback was the expansion with CME’s WIDI Bluetooth MIDI ecosystem. Instead of requiring an internal module, people can simply attach a WIDI Uhost or WIDI Jack externally. Placing the WIDI device anywhere on the H12 chassis provides clear line-of-sight for improved wireless performance.
6-in / 6-out TRS MIDI ports
Connect MIDI devices via 3.5mm (1/8″) TRS MIDI I/O, with Type A or Type B selectable via software for broad hardware compatibility.
Expanded USB MIDI connectivity
Six USB-C Host ports support up to 16-in / 16-out USB MIDI, expandable via standard USB hubs. A dedicated USB-C Client port provides 8-in / 8-out virtual MIDI for computers and mobile devices.
Future-proof 32-bit processor
High-performance processing enables precise MIDI handling with fast and reliable data transmission.
High-speed optocoupler
Ensures secure and stable MIDI input with accurate signal isolation and reliable synchronization between devices.
Near-zero latency performance
Accurate and jitter-free transmission of all MIDI messages, including clock, SysEx, MTC, and MPE.
HxMIDI Tools software
Configure MIDI routing, splits, merges, filtering, and message mapping using the free HxMIDI Tools software with support for six presets.
