I have it hooked up now. So the driver is required by the host if you want to use the AVB Mixer. Therefore it has to connect to a computer if you want to make any changes at all to the mixer (this is probably what I was thinking of earlier wrt its limitations when recording to iPad)
Set it up as a class compliant interface with AUM, you definitely don’t get the great low latency that the AVB driver provides. 128 samples is the minimum I can run with this Apple A8 processor. Might be better with a more recent iPad Pro.
Would be ultra-fiddly and annoying to use this solely with an iPad and no computer, frankly.
I don’t have issues with fan noise, as I run an iMac, YMMV.
If you had to do it, iPad only, I’d use AUM to record, since it allows you to run EQ and Audio Unit plug-ins.
