Mixtrack Pro (3) with iOS - does audio work?

I am thinking of buying a mixtrack Pro 3. I use dJay on iOS (iPad 2018) and my android phone, but I’m mainly thinking about using this with my iPad

I can see from the compatibility list it’s not plug and play but it is compatible via an adaptor.

What I want to know, is whether it just works as a Midi controller with iOS or if the audio interface element works also. IE the sound comes out of the main and cue outputs of the mixtrack Pro and your not stuck with just the headphone out from the iOS device.

Can somebody confirm?

ps if it makes a difference which version of dJay, it doesn’t matter, I’ll willingly pay if I need a different version for it to work correctly.
