# CME WIDI Bud Pro * Dual Role Bluetooth-LE MIDI (Host & Peripheral) * Low Latency * Driver-Less Operation\* The CME WIDI Bud Pro is a fantastic way to interface [Mezzz](/sleepy-circuits/mezzz-and-vidos/mezzz-manual.md) with [Hypno](/sleepy-circuits/hypno/hypno-manual.md). The bi-directional Bluetooth USB MIDI interface is plug-and-play, making it easy to use with nothing to install. Use it to combine Mezzz with other USB devices that lack a Bluetooth connection, or wirelessly send MIDI information to Hypno using our [Hypno4Live Max Device.](https://sleepycircuits.com/hypno-for-live) The WIDI Bud Pro is a great addition to any of our Sleepy Circuits products. **\*WINDOWS 11 users**: In order for the WIDI Bud Pro to be recognized by computers running Windows 11, a new driver is required.
