WIDI Jack, Quad Cortex trouble shoot

Hello guys

I’m using a BBeat to send backing tracks, clicks and MIDI signals via WIDI Jack to my Quad Cortex, which also has a WIDI Jack. Most of the time it works—I mainly use it to switch between presets and scenes—but occasionally, the QC lights up like a Christmas tree, and the blocks start turning off and on erratically.

Has anyone experienced anything like this ?

What are y’all using for midi?
