My printer has an ability to connect directly to a computer without a router and a wireless connection in place. I am unaware if this is a specific chip or just how things are programmed. My idea is to potentially use the Quad Cortex’s WiFi connection option to connect directly to your phone, this way allowing an app to be utilized for configurations similar to the Nano Cortex. It’s just instead of using your phones bluetooth, the wifi would be used. Unsure of limitations of hardware, you may only be able to connect to just the cortex at a time. I am also used to doing something similar for in-ear mixing with PAs but usually there is a router involved. Maybe a USB stick that acts as some form of router since the QC can use internet over the USB port? Just Spit balling
