3. Setup Instructions
Follow these steps to set up your Midiplus USB MIDI Host Controller:
- Power Connection: Connect the included 5V power adapter to the "5V Power" port on the rear of the USB MIDI Host. Plug the adapter into a standard electrical outlet. The unit will power on automatically.
- Connect USB MIDI Device: Plug your USB MIDI keyboard or controller into the "USB Host" port located on the front of the Midiplus unit. Ensure the USB device is compatible with standard USB MIDI protocols.
- Connect 5-pin MIDI Device:
- To send MIDI data from your USB device to a 5-pin MIDI device, connect a standard 5-pin MIDI cable from the "MIDI OUT" port of the Midiplus unit to the "MIDI IN" port of your target MIDI device.
- To receive MIDI data from a 5-pin MIDI device and route it to your USB device, connect a standard 5-pin MIDI cable from the "MIDI OUT" port of your 5-pin MIDI device to the "MIDI IN" port of the Midiplus unit.
- Verify Connection: Once all connections are made, your USB MIDI device should be able to communicate with your 5-pin MIDI device. Refer to your specific MIDI devices' manuals for further configuration if needed.
4. Operating Instructions
The Midiplus USB MIDI Host Controller operates as a bridge between USB MIDI and traditional 5-pin MIDI. It is designed for plug-and-play functionality without requiring complex software configuration for basic use.
- MIDI Data Flow: MIDI messages from the connected USB device are automatically converted and sent to the 5-pin MIDI OUT. Conversely, MIDI messages received at the 5-pin MIDI IN are routed to the connected USB device.
- Panic Button: If you experience stuck notes or unexpected MIDI behavior, press the "Panic" button on the front panel. This sends an "All Notes Off" message across all MIDI channels, clearing any hanging notes.
- Supported Software: While primarily a hardware host, the device is compatible with various DAW software that support input/output, such as Ableton Live, Logic Pro, FL Studio, etc., on Windows, macOS, or Linux operating systems when connected to a computer.
