CME H12MIDI Pro

The H12MIDI Pro is a compact USB Host + TRS MIDI interface designed for players and producers who need a flexible, standalone MIDI hub. It combines USB host and client connectivity with 6-in/6-out TRS MIDI I/O in a durable, pedalboard-friendly format.

Built around a future-proof 32-bit processor and high-speed optocoupler, it delivers highly accurate MIDI transmission with close to zero latency and jitter. It supports all standard MIDI messages, including clock, SysEx, MIDI Timecode and MPE, making it suitable for demanding studio and live setups.

The H12MIDI Pro works fully standalone, with all routing, filtering, merging and mapping stored internally. It also supports USB-C client mode for computer connectivity, giving you 8-in/8-out virtual MIDI ports without the need for drivers.

With dual power options, 25 LED indicators and free HxMIDI Tools software for configuration and firmware updates, the H12MIDI Pro is built to keep complex MIDI rigs organized, portable and easy to manage.
