Bottom line: The CME WIDI Uhost Premium Bluetooth MIDI Interface & USB Host | Works with Class-Compliant Instruments, Controllers & Keyboards, Windows, Mac, iOS, Android, Linux, ChromeOS is a specs-and-price decision rather than a crowd-consensus one in the audio & midi category, priced around $49.99. Check the specification table above against one or two close alternatives — on price and spec fit, not on star ratings.

The CME WIDI Uhost is a Bluetooth MIDI interface and USB host that cuts your class-compliant controller loose from the computer entirely. Plug it into a keyboard, pad controller, or drum machine and it turns that USB MIDI port into a wireless Bluetooth MIDI endpoint, so you can pair with Windows 10/11, macOS, iOS, Android, Linux, or ChromeOS without a laptop tethered to your rig. CME rates it at 3 ms latency between two WIDI devices with sub-1 ms jitter, and Adaptive Frequency Hopping holds the link out to 65 ft (20 m) line-of-sight, which is the difference between studio-desk convenience…

Frequently Asked Questions

Will the WIDI Uhost work with my MIDI keyboard?

It works with class-compliant USB MIDI instruments, controllers, and keyboards, which covers most modern gear. CME maintains a compatibility list at bluetoothmidi.com; check your specific model there before buying.

How much latency does Bluetooth MIDI add?

CME rates the Uhost at 3 ms latency between two WIDI devices, with ultra-stable sub-1 millisecond jitter. You can also bias the tuning toward lower latency or lower jitter in the WIDI App.

Can I just pair it in my phone's Bluetooth settings?

No. CME states that general Bluetooth pairing does not work for Bluetooth MIDI. Update the firmware through the WIDI App first, then follow the step-by-step pairing guide for iOS, macOS, Windows 10/11, or Android.

What is the wireless range?

Up to 65 ft (20 m) line-of-sight. Adaptive Frequency Hopping minimizes interference from other 2.4 GHz traffic, which matters on a crowded stage or in a busy studio.

Can I connect more than two devices at once?

Yes. The WIDI App supports Bluetooth MIDI groups of up to 5 devices, including MIDI merge and split configurations, plus automatic group learning between WIDI units.
