## Summary description

MIO MIDITECH 4merge is a USB MIDI interface with four MIDI inputs and one MIDI output for connecting multiple MIDI devices to a computer. It provides routing and merging of incoming MIDI signals into a single USB stream for DAWs, sequencers, or live setups. Suitable for studios and stage use where consolidating multiple controllers or instruments is required.

## Long description

The MIO MIDITECH 4merge USB is a compact MIDI interface that consolidates signals from multiple MIDI devices into a single USB connection for a computer. With four MIDI inputs and one MIDI output, it routes and merges incoming MIDI data into a unified USB stream compatible with digital audio workstations, sequencers, and live performance setups. The device is designed for straightforward integration into studio and stage environments where several controllers or instruments must be connected simultaneously.
Advantages
The interface supports four independent MIDI inputs that are merged into one USB stream, reducing the need for multiple USB adapters or complex routing configurations. Its single MIDI output allows sending combined MIDI data back to an external synth or controller. The compact form factor and USB connectivity make it practical for desktop studios and portable live rigs. The unit is bus-powered via USB, which simplifies installation and eliminates the need for an external power supply in most setups.
Suitable for
Home and project studios that use several MIDI controllers or keyboards
Live performers needing to consolidate multiple MIDI sources into one computer input
Producers and composers working with DAWs and hardware sequencers
Rehearsal rooms and educational setups with multiple MIDI instruments
Key specifications
Connectivity: 4 MIDI DIN inputs, 1 MIDI DIN output, USB for computer connection
Function: merges and routes incoming MIDI signals into a single USB MIDI stream
Power: bus-powered via USB (no external power supply required for typical use)
Compatibility: standard class-compliant MIDI device for major operating systems and DAWs
Form factor: compact desktop unit suitable for portable and stationary setups
How to use
Connect up to four MIDI sources to the MIDI DIN input ports and connect the MIDI output to an external MIDI device if required. Plug the USB cable into the computer; the interface will appear as a single USB MIDI device in the operating system and in your DAW or sequencer. Configure MIDI input routing and device channels within your software as needed. Use the merged USB stream to receive combined MIDI data from multiple controllers or instruments and route MIDI from the computer back to the external MIDI output when necessary.
Usage recommendations
For reliable operation, connect devices with proper MIDI wiring and avoid daisy-chaining active MIDI outputs. Verify channel assignments and MIDI routing in your DAW to prevent overlapping controller messages. In live scenarios, test the combined MIDI stream during soundcheck to ensure correct mapping and latency performance.
