I think both of your questions are answered on the page. Maybe not in the direct manner in which you have asked, but my understanding is that recording is possible with the mixer accessory mentioned towards the bottom, and the antennas are for the Bluetooth MIDI feature heavily emphasised towards the top. Maybe they do need a FAQ with a basic Q&A format, though. e.g. Why does it have antennas? How do I record? What do the knobs do? How many instruments are included? How do I transfer recordings to my computer or phone? etc.
