Not personally, I always turn to a laptop/desktop for DAW stuff, or make do with the 18 channels of the Qu-drive for “unexpected” recording requests.
I can’t find the actual announcement now, but it said:

We have recently completed a series of tests with the Qu USB interface, recording to / playing from iOS devices via the Apple ‘Lightning to USB Camera adapter’, and we are pleased to confirm that the latest generation of iPad Air and iPad Mini can successfully record and stream up to 32 tracks!
You can now use Qu mixers with a number of DAW apps including Auria, Steinberg Cubasis, GarageBand, FL Studio HD and Presonus Capture.”
