Maintenance
To ensure the longevity and optimal performance of your Worlde Easykey.25, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to wipe the surface of the controller. For stubborn dirt, slightly dampen the cloth with water. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish.
- Storage: When not in use, store the controller in a clean, dry place away from direct sunlight, extreme temperatures, and excessive humidity.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Do not place heavy objects on top of the controller.
- Connectivity: Always handle the USB cable by the connector, not the cable itself, to prevent damage to the cable or the port.
Troubleshooting
If you encounter issues with your Worlde Easykey.25, please refer to the following common solutions:
- Device Not Recognized:
- Ensure the USB cable is securely connected to both the controller and your computer.
- Try connecting to a different USB port on your computer.

- Ensure that the correct instrument or sound is loaded and armed for recording/playback in your software.
- Check the volume levels within your software and on your audio output device.
- Keys Not Responding Correctly:
- Check if the octave buttons have shifted the keyboard to an extreme range (very high or very low) that might not produce audible sound with your current instrument.
