Modes de funcionament
The XMSJSIY USB MIDI Interface Box features a mode-switching button to select between USB mode and various MIDI Thru modes. The LED indicators provide visual feedback on the currently active mode and MIDI signal transmission.
Mode USB
In USB Mode, the interface acts as a standard USB MIDI device, allowing your computer to send and receive MIDI data to and from the connected MIDI instruments. Each of the 4 MIDI IN and 4 MIDI OUT ports can be individually addressed by your Digital Audio Workstation (DAW) software.

USB Mode: All 4 MIDI INs from instruments connect to the interface, and all 4 MIDI OUTs from the interface connect to instruments, all routed through the USB connection to a computer.
MIDI Thru Modes
The MIDI Thru modes allow the interface to function as a standalone MIDI router/splitter without requiring a computer connection. Use the mode button to cycle through the available Thru modes.

MIDI Thru Mode 1: Each MIDI IN (1-4) is routed directly to its corresponding MIDI OUT (1-4).

MIDI Thru Mode 2: MIDI IN 1 is routed to MIDI OUTs 1, 2, 3, and 4. MIDI INs 2, 3, and 4 are not routed.

MIDI Thru Mode 3: MIDI IN 1 is routed to MIDI OUTs 1 and 2. MIDI IN 2 is routed to MIDI OUTs 3 and 4. MIDI INs 3 and 4 are not routed.

MIDI Thru Mode 4: MIDI IN 1 is routed to MIDI OUT 1. MIDI IN 2 is routed to MIDI OUT 2. MIDI IN 3 is routed to MIDI OUT 3. MIDI IN 4 is routed to MIDI OUT 4.

MIDI Thru Mode 5: MIDI IN 1 is routed to MIDI OUTs 1, 2, 3, and 4. MIDI INs 2, 3, and 4 are not routed.

Resolució de problemes
If you encounter issues with your MIDI interface box, refer to the following troubleshooting tips:
- Sense indicador d'alimentació: Ensure the USB cable is securely connected to a 5V DC power source or a powered USB port. Try a different USB port or power adapter.
- No USB Operation Indicator: Verify the USB connection to your computer. Try a different USB port on your computer. Ensure your computer's operating system recognizes the device (check Device Manager on Windows or System Information on macOS).
- No MIDI Signal Transmission:
- Check all MIDI cable connections between the interface box and your instruments. Ensure MIDI OUT is connected to MIDI IN, and vice-versa.
- Verify the correct operating mode is selected using the mode button. Ensure you are in USB mode if using with a computer, or the appropriate MIDI Thru mode for standalone operation.
- Confirm that your MIDI instruments are powered on and configured to send/receive MIDI data on the correct channels.
- In your DAW or music software, ensure the XMSJSIY MIDI interface is selected as the input/output device and that MIDI routing is correctly configured.
- Intermittent Connection/Signal Loss: Ensure the USB cable is not damaged and is securely connected. Avoid using excessively long or unshielded USB cables.
