What is WIDI Jack?

WIDI Jack is your virtual MIDI interface Now you can connect all your MIDI devices with standard MIDI I/O wirelessly via Bluetooth MIDI. Enjoy ultra-low 3ms latency and secure connectivity via Adaptive Frequency Hopping.

Smart Connectivity Algorithms

**Latency is not an issue with WIDI. **WIDI distinguishes itself from any other Bluetooth MIDI technology available through its unique SCA technology. SCA is a collection of highly effective algorithms that optimize performance and minimize interference.

Latency is reduced to an inaudible 3ms as measured between 2 WIDI devices. MIDI transmits data at a standard rate of 31.25 kbps via cable. WIDI products go up to 400 kbps.

Configure 1-on-4 or 4-on-1 MIDI thru, split and merge setups that automatically connect from memory.

WIDI Jack vs. WIDI Master

TRS/DIN MIDI cable options | external power via USB-C (No data)

With 5 different cable options, WIDI Jack is compatible with almost any MIDI device via standard MIDI I/O (not USB MIDI).

WIDI Jack even works with unpowered MIDI OUT ports, devices with only MIDI IN and can switch between TRS MIDI type A/B.

Optional MIDI cables for TRS 2.5mm, 3.5mm (1/8") and 6.35mm (1/4") and switch for Type A and B.

Connect all 5-pin DIN MIDI devices. Even devices with only MIDI IN via optional USB-C port for power.

Connect MIDI devices with more rare DIN-6-mini MIDI ports like the Yamaha Reface Series.

Connect all MIDI devices. Even devices with unpowered MIDI ports via USB-C port for power.
