Hi,
the Reason that set apart this audio interface From others(at least for me) was the fact it is class compliant and thus can work with An ipad as well as it can power on a mobile battery and has a built in usb hub.
So, before this audio interface I connected my midi controller to the Apple CCK USB3 Adapter and it worked flawlessly.
Now, when i’m Using it and powering the Audiofuse through a powerbank, the midi controller doesn’t work.
It gets recognized by the iPad but nothing is coming through.
The IPad i’m Using is the iPad Pro 12.9 2nd generation.
The midi controller i’m using is the Joue Play, if I understood correctly they’re your partners as Arturia soft was included with the purchase, hope it will be fixed soon.
