The WC-1 is a compact USB wireless adapter that connects your compatible Roland hardware to the Roland Cloud ecosystem. Plug it in, open the iOS or Android app, and you can browse and install Sound Packs, Wave Expansions, and Model Expansions directly to your instrument. Wi-Fi supports both 2.4 GHz and 5 GHz bands via IEEE 802.11 a/b/g/n, and Bluetooth 5.0 handles the mobile connection.

The included one-year Roland Cloud Pro membership is the real value here, unlocking unlimited access to all Model Expansions, Wave Expansions, and Sound Packs across your compatible Roland instruments. That's over 30,000 sounds to explore. The adapter itself is tiny (under an ounce) and draws just 80 mA of USB bus power. A great way to expand your Roland keyboard's sound library without any cable tethering.
