6. Troubleshooting
If you encounter issues with your M-VAVE MS1 Wireless MIDI System, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| MIDI A indicator light flashes continuously. | Units are not paired or connection is lost. | Ensure both MIDI A and MIDI B are powered on and within range. Restart both units. Check connections to MIDI instrument and computer. |
| No MIDI signal received by computer/DAW. | Incorrect driver, software settings, or connection. | For Windows 10, install the Korg BLE MIDI Driver. Verify MIDI input settings in your DAW. Ensure MIDI A and MIDI B are successfully paired (solid light). Check physical connections. |
| Notes are sticking or not sending reliably. | Interference, low battery, or firmware issue. | Ensure MIDI A is fully charged. Minimize wireless interference from other devices. Check for firmware updates from the official M-VAVE website. |
| MIDI B not recognized by computer. | Faulty USB port or driver issue. | Try a different USB port. Reinstall necessary drivers (e.g., Korg BLE MIDI Driver for Windows). Test MIDI B on another computer if possible. |
If the problem persists after trying these solutions, please contact customer support.
