Advanced Wireless MIDI - Ultra-low latency premium Bluetooth MIDI


What is WIDI Uhost?

WIDI Uhost is your Bluetooth MIDI Interface + USB host.

Add Bluetooth MIDI to your class compliant MIDI controllers, instruments and computers via USB. 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.

Plug, pair & play

Transmit and receive Bluetooth MIDI via the USB port of your MIDI device or computer.
