[Ultra-Low 3ms Latency]
WIDI provides highly effective smart connectivity algorithms with just 3ms delay between two WIDI devices. Adaptive frequency hopping minimizes interference. Maximizes reach to 65 feet of plain sight.
[Personalization Performance]
Find the WIDI app (iOS/Android) for lifetime updates, automatic group learning, and personalization settings. Optimize performance for latency or jitter. Create MIDI merge/split setups via Bluetooth MIDI groups using up to 5 devices.
[!! Caution!!]
General Bluetooth pairing does not work with Bluetooth MIDI. First update the firmware via the WIDI app. Please follow the exact pairing instructions for optimal performance. Get 24/7 support from bluetoothmidi(dot)com.
WIDI is a 100% community-driven technology that has been verified by thousands of community members around the world. You are a true evangelist for our products. WIDI Uhost is a premium Bluetooth MIDI adapter that uses standard USB power (USB bus power, USB power, USB power bank). WIDI Uhost can pass 500mA (USB 2.0 standard) to power any (bus-powered) USB MIDI device connected to WIDI Uhost. Check the open source compatibility list at bluetoothmidi(dot)com. Only one WIDI device is required to pair with a standard Bluetooth MIDI controller and operating system. To pair two MIDI devices, you need two WIDI devices. No computer. You can also add up to 5 WIDI devices per cable-free Bluetooth MIDI group. W.I.D.
Easily create 1:4 MIDI split/thru and 4:1 MIDI merge wirelessly by simply enabling Group AutoLean in the I-app (iOS/Android).
[Important]
General Bluetooth pairing does not work with Bluetooth MIDI. Be sure to update your firmware before you begin. For optimal performance as advertised, follow the exact pairing instructions for macOS, iOS, Windows 10, and Android. You can find all guides and videos on CME's support website.
[Features & Recommended Points]
●Bluetooth 5 + Ultra-Low Latency (Approx. 3ms)
Even when connected via Bluetooth MIDI, latency is minimized, providing an experience close to wired connections for live performances and real-time playing.
●3-in-1 Mode Supporting Both USB Host and USB Device
Can be used directly as a host for devices such as controllers or keyboards when connecting USB MIDI instruments and using Bluetooth MIDI. Additionally, it functions as a USB device when connected to a computer or mobile device, offering maximum flexibility in connection setups.
●Cross-Platform Compatibility
Supports major operating systems including Windows, macOS/iOS, Android, Linux, and ChromeOS. Devices supporting BLE (Bluetooth Low Energy) MIDI or class-compliant USB MIDI often require no drivers.
●Wide MIDI Message Compatibility
Can send and receive various MIDI messages over Bluetooth, including Note, Control Change (CC), MIDI Clock, SysEx, and MPE, with minimal impact on performance or expressiveness.
●Group Connection Function (WIDI Groups)
Can manage up to five Bluetooth MIDI devices in a group, allowing one to act as the central device and others as peripherals. This enables splitting or merging connections among multiple instruments, ideal for setups controlling several instruments simultaneously.
●Flexible Power Supply Options
Operates via USB bus power and can also be powered through an external 5V USB-C connection. Provides up to 500mA to connected USB devices (bus-powered), making it safe to connect controllers and other USB instruments directly.
●Compact Size & Easy Placement
Lightweight and compact (approx. 34 × 38 × 14 mm, 18–19g). With the included magnetic stickers, it can be attached to equipment, helping keep cables organized. Convenient for both stage and mobile use.
●Reliable Connection Stability & Noise Suppression
Equipped with Adaptive Frequency Hopping and proprietary Smart Connectivity Algorithms (SCA), reducing interference and signal drops. Ensures high reliability in live and recording environments.
●Firmware Update Support & Future-Proofing
Firmware can be updated via a dedicated iOS/Android app. Future updates may add support for the latest Bluetooth MIDI standards and features, making it a long-lasting solution.
[Summary]
The CME WIDI Uhost is a Bluetooth MIDI / USB MIDI interface designed to deliver “cable-like response wirelessly.” It combines USB host/device switching, cross-platform compatibility, extensive MIDI message support, group connections, flexible power options, and convenient placement, maximizing convenience and flexibility from every angle.
Ideal for live performance, mobile music production, stage setups, classrooms, or studios managing multiple devices, it excels in diverse scenarios.
If you want to “free yourself from tangled cables,” “connect multiple devices hierarchically or wirelessly,” or “perform without perceiving latency,” the WIDI Uhost is a highly compelling choice. This device simplifies your MIDI environment, increases freedom, and allows you to focus fully on playing and production.
