Critic Reviews

CME WIDI Master review | MusicRadar

musicradar.com

The CME WIDI Master offers a simple yet effective solution for wireless MIDI connectivity, enabling seamless integration with both traditional and Bluetooth LE devices. Its detachable design is a notable advantage, allowing flexibility in setup. However, users must purchase two units for full MIDI socket-to-socket functionality, which could be an inconvenience for some. The pairing process is straightforward, with commendable stability at a distance of up to 10 meters. While latency is present, it remains negligible in practical use. Overall, this innovative device liberates musicians from cable constraints but requires careful consideration of purchasing multiple units for complete functionality.

WIDI Master - CME - Waveform Magazine

waveformmagazine.com

CME's WIDI Master is a game-changer for MIDI connectivity, liberating musicians from the chaos of cables with its seamless Bluetooth integration and a latency of just 3 ms. The setup is intuitive, making it easy to connect devices like the Keystep and Sequential Pro 3 without a hitch. However, it's worth noting that to truly maximize its potential, you’ll need two units for multi-device communication. While the initial pairing might require a few steps, the payoff is well worth it as it enhances expressive control and reduces clutter in both studio and live settings. Overall, it's an affordable and effective solution for modern musicians looking to streamline their workflow.
