Which cable do I need for my ROLI or LUMI piano?
USB-C to USB-C, or USB-C to USB-A? How to pick the right cable to connect your ROLI or LUMI piano to a Mac or PC.
The keyboard side is USB-C
Use a cable with USB-C on the keyboard end. The other end must match your computer.
Recent Macs and PCs
Computers with USB-C ports need a USB-C to USB-C cable. Older ones with USB-A ports need USB-C to USB-A.
It must carry data
Charging-only cables power the keyboard but the computer never sees it. If the piano is not detected, try another cable first.
How to tell a data cable from a charging-only cable
There is often no visible difference. The simplest test: plug the keyboard into the computer and check whether it appears. On a Mac, open Audio MIDI Setup and show the MIDI Studio window. On Windows, look in Device Manager. If the keyboard charges but never appears, the cable probably carries no data.
Adapters and hubs
A simple USB-C to USB-A adapter works fine. USB hubs and docks can sometimes cause problems: if the keyboard is not detected through a hub, plug it directly into the computer. Avoid very long or very cheap cables.
Cable or Bluetooth
A cable is the most reliable choice: no pairing, no delay and the keyboard charges while you play. Bluetooth MIDI is convenient on a Mac but can add a small delay and disconnect when the battery is low.
