    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.
