WIDI Jack – Turn Your MIDI Device into a Premium Bluetooth MIDI Powerhouse
WIDI Jack brings wireless MIDI to any device with standard MIDI I/O: connect synths, drum machines, and pedals via TRS or 5-pin DIN cables, with optional USB-C power for unpowered ports or MIDI In-only devices. No drivers. No cable clutter. Just fast, stable wireless MIDI.
Get Rid of MIDI Cables!
Streamline your setup and simplify your signal flow. WIDI enables direct wireless Bluetooth MIDI connections between your devices, reducing cable clutter and making it easier to build, adjust, and expand your workflow. Spend less time routing — and more time creating.
Latency and jitter are not an issue!
MIDI transmits data at a standard rate of 31.25 kbps via cable. WIDI products go up to 400 kbps. With CME’s Smart Connectivity Algorithm (SCA), latency can be as low as 3 ms between two WIDI devices, while maintaining stable 1ms jitter performance up to 20 m (65 ft) line of sight.
All Your MIDI Connections - Fully Covered
MIDI I/O to MIDI I/O
Hardware to Hardware (No Computer Required)
Connect two MIDI devices wirelessly with two (2) WIDI adapters - automatic pairing makes setup effortless. Create WIDI groups to manage multiple fixed pairs, so they reconnect exactly as configured, instantly every time.
Bluetooth MIDI to MIDI I/O
