Introduction
The Miditech USB MIDI Host is a compact and efficient tool designed to bridge the gap between USB MIDI devices and traditional 5-pin DIN MIDI connections. It enables USB MIDI devices, such as keyboards, controllers, or drum trigger pads, to communicate with other MIDI equipment that uses standard DIN MIDI ports, without requiring a computer.
This device converts USB MIDI data into DIN MIDI data, allowing your USB MIDI peripherals to integrate seamlessly into a traditional MIDI setup. Power for the connected USB MIDI device is supplied via the USB Host port.
Package Contents
- Miditech USB MIDI Host MIDI Interface (Model MIT-00155)
- Note: An optional USB power supply (5V) may be required and is not always included. MIDI cables are sold separately.

Key Features:
- Compact and robust design.
- One USB HOST Interface (for USB MIDI peripherals).
- One 5-pin DIN MIDI IN interface.
- One 5-pin DIN MIDI OUT interface.
- Converts incoming USB MIDI data to DIN MIDI data.
- Provides power to the connected USB MIDI device via the USB Host port.
Setup
- Connect USB MIDI Device: Plug your USB MIDI keyboard, controller, or drum trigger pad into the USB Host port (Type A) on the Miditech USB MIDI Host. Ensure the connection is secure.
- Connect DIN MIDI Devices:
- To send MIDI data from your USB device to other MIDI equipment, connect a standard 5-pin DIN MIDI cable from the MIDI OUT port of the Miditech USB MIDI Host to the MIDI IN port of your receiving MIDI device (e.g., synthesizer, sound module).
- To receive MIDI data from other MIDI equipment into your USB device (if supported by the USB device), connect a standard 5-pin DIN MIDI cable from the MIDI OUT port of your sending MIDI device to the MIDI IN port of the Miditech USB MIDI Host.
- Power Supply (Optional): The Miditech USB MIDI Host can be powered via an external 5V USB power supply (not always included). Connect a Micro USB cable to the "5V Power" port on the device and plug the other end into a suitable USB power adapter. This is often necessary if the connected USB MIDI device draws significant power or if the host device itself requires stable external power for optimal performance.
- Power On: Once all connections are made, power on your connected MIDI devices. The Miditech USB MIDI Host should automatically detect and establish communication with the connected USB MIDI device.
Operating Instructions
The Miditech USB MIDI Host operates automatically once connected. It acts as a transparent bridge, converting MIDI messages between the USB MIDI protocol and the traditional 5-pin DIN MIDI protocol.
- USB to DIN MIDI Conversion: MIDI data generated by your USB MIDI device (e.g., notes, control changes) will be sent from the USB Host port, converted by the Miditech device, and then output through its 5-pin DIN MIDI OUT port to any connected DIN MIDI equipment.
- DIN to USB MIDI Conversion: MIDI data received at the 5-pin DIN MIDI IN port will be converted and sent to the connected USB MIDI device via the USB Host port. This functionality depends on the USB MIDI device's ability to receive MIDI input.
- Power for USB Device: The USB Host port provides power to the connected USB MIDI device. For devices requiring more power, or for stable operation, ensure the Miditech USB MIDI Host is connected to an external 5V USB power supply.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Ensure cables are connected and disconnected gently to prevent damage to the ports.
