iPad Recording

Sorry if this has already be asked or answered,

but I saw you can record to iPad using the Lightning to camera adapter. do you then connect it with a USB cable to the Q-Drive?

Sorry i am a bit of a Noob at this whole thing but am loving learning!

I am wanting to use it to record a couple of songs live and then play back later to learn and muck around with the mix.

i also have a Mac Book Would i be better off by purchasing Logic Pro x instead. the price difference is significant considering i already have the iPad

USB to the back of the mixer, not the q drive.
