CME WIDI Jack Wireless MIDI Interface - Ultra Low Latency Bluetooth

In this review the CME WIDI Jack is examined as a practical wireless MIDI interface for musicians and studio users who want to eliminate cable clutter and gain stage freedom. The single biggest reason to buy is its reliable low-latency Bluetooth MIDI link that delivers near-instant performance between compatible devices, making it useful for live rigs and home studios that need dependable wireless transmission without sacrificing responsiveness.

Key Features

• Wireless MIDI: Lets users add Bluetooth MIDI to existing MIDI gear so you can remove bulky TRS/DIN and USB-to-MIDI cables and tidy your workspace.
• Plug, Pair & Play: Automatically pairs between WIDI devices and Bluetooth MIDI controllers so setup is straightforward across iOS, macOS, Windows 10/11 and Android.
• Full MIDI Support: Transmits all MIDI messages including SysEx and MPE, which keeps advanced controller gestures and device management intact over Bluetooth.
• Ultra low 3ms latency: Uses Smart Connectivity Algorithms to minimize delay between two WIDI devices, which is critical for real-time performance and playing feel.
• Extended range and stability: Adaptive Frequency Hopping and a line-of-sight reach up to 65ft help reduce interference and keep a stable connection on stage or in the studio.
• App optimisation: WIDI App provides firmware updates and lets you tune performance for lower latency or reduced jitter and group up to five devices.

Who It's For

The WIDI Jack is aimed at gigging musicians, synth players and producers who need a compact way to connect keyboards, guitar pedals, wind controllers or other MIDI gear without being tethered by cables. It is particularly well suited to setups that benefit from the ultra low 3ms latency and to users who want SysEx and MPE supported wirelessly.

Users with very old or nonstandard MIDI equipment should check device compatibility before buying, and those who prefer a permanently powered hub may prefer wired MIDI interfaces since the WIDI Jack expects power via MIDI Out or optional USB-C external power for some setups.

Pros & Cons
