I have search the forum to see if there is any difficulty in using Zoom H4n as an audio interface with iPad iOS 8 and Cubasis. The H4n is Class Compliant and connects to Garage band, well i get a signal in GB. I have not yet recorded anything in GB.
I have connected the H4n to a powered USB dock and connected the iPad Air 2 via a Apple Lightning adaptor cable to the USB primary port. I get no signal in Cubasis.
I have checked Cubasis using an UR44 and that works okay.
I know that Apple makes it very difficult for its users who stray from the pack but I have a H4n and I like it and it is very convenient.
That failing is there another bridging app that can make the link from H4n into Cubasis.
I am sure this question will have come up before but every search takes me to the Cubase Forum!
Edit: I have no signal in GB either. The signal I was picking up was the built in ipad mic!
So I guess it is a no go, pity
