The essentials to know about the wireless MIDI cable (Bluetooth) CME WIDI MASTER
- Transforms your 5-pin DIN MIDI ports into MIDI Bluetooth to play and sync without cables, even without a computer
- Ultra-low latency advertised at only 3 ms for a natural playing feel both in the studio and on stage
- Automatic pairing and smart master/slave switching for quick setup
- Advanced message handling: MIDI Clock and SysEx for drum machines, sequencers, and complex configurations
A modern MIDI gateway to free your setup
The CME WIDI MASTER fits into an approach designed to replace traditional MIDI connections with reliable Bluetooth MIDI connectivity. Built around intelligent connectivity algorithms, it aims to simplify wireless integration into an existing setup without changing your instruments. The idea is simple: keep your favorite MIDI machines and gain flexibility, whether for a rack, a compact studio corner, or a stage where every cable counts.
For whom and in what uses?
This virtual MIDI cable is intended for musicians and technicians who want a
cleaner and faster-to-deploy MIDI setup: keyboardists, electro/techno producers, groovebox users, drum machines, and step sequencer users. It suits both advanced users and beginners thanks to automatic pairing. In live settings, it helps reduce failure points related to cabling; in the studio, it facilitates instrument placement, remote control, and tempo synchronization via MIDI Clock.
Features and innovations
The WIDI MASTER operates as a
wireless MIDI cable compatible with the MIDI over Bluetooth Low Energy standard, relying on Bluetooth 4/5 connectivity. Its SCA technology includes optimization algorithms targeting stability, range, and latency reduction, with features such as dual-role automation, automatic pairing mode, and smart hub logic. It supports MIDI message transmission, including
SysEx, and enables precise synchronization of your machines via
MIDI Clock. The detachable design allows connecting only the necessary part, with a separate adapter for MIDI OUT only, and a convenient 45-degree bridge cable when access to DIN ports is vertical. No power adapter is required: power is drawn via the MIDI OUT DIN at 3.3 V or 5 V. Finally, firmware updates are wireless via the WIDI app on iOS and Android, allowing you to benefit from improvements and new features over time.
