Replying to my own post, as nobody has responded at all! I bought the official Apple USB C to Lightning adapter a couple of days ago. I wanted to use my Sonic Port (non VX) with an iPad Air (USB C connector). All looked promising, as when I connected the Sonic Port the Mobile Pod software on it unlocked and showed the Sonic Port as a connected device within the Mobile Pod software. However, when I tried to play my guitar through it there was no sound. When I plugged the Sonic Port in a second time the red LED on top flashed very briefly and this time it would not unlock within the Mobile Pod app, which showed "no device connected". Since then the Mobile Pod app on the iPad Air has not recognised the Sonic Port device at all via the adapter, despite multiple resets, plugging in and unplugging, reloading the app, etc. I am very disappointed as Apple claim that this new adapter can pass power, data and audio. I tried the Sonic Port again on my older Lightning port iPad mini and as before it worked perfectly.
Subsequently I have tried using the adapter to charge the iPad Air from a Lightning lead (official Apple one), connected to a charger, but it will not charge. In my car, the iPad Air will not connect to the infotainment system or charge via a lightning cable and the Apple USB C to Lightning adapter, although it will connect via a USB C to USB A lead. So it seems that not only does the new Apple USB C to Lightning adapter not work with the Sonic Port, it does not work with anything else! I will be returning it to the store. I hope this post saves some time and hassle for others. Basically the Sonic Port does not work with USB C iPads and it is pointless trying to get it to work.
