Q: The USB MIDI device on my ES520 portable piano is sometimes not detected correctly by my computer — what should I do?

Try different USB ports, restart both devices, update drivers, and use a different cable. USB 2.0 ports work most reliably.

If your computer intermittently fails to recognise the ES520 as a USB MIDI device, try the following steps: Connect to a different USB port on your computer — USB 2.0 ports generally work most reliably with Kawai instruments. Try a different USB cable, as faulty cables are a common cause of intermittent detection issues.

Restart both the ES520 and your computer, then reconnect. On Windows, open Device Manager and check for any unknown devices or error indicators next to the piano. If found, right-click and update the driver. On Mac, open Audio MIDI Setup (Applications > Utilities) to confirm the piano appears as a MIDI device.

Ensure your operating system is fully up to date. If the issue persists, check the Kawai support website for any driver downloads for the ES520, or contact your local Kawai authorised dealer for further assistance.
