The connection with Big Sur works perfectly if the ME is connected to the Mac directly or via USB Hub. But if I connect it with my iConnectivity Audio 4+(ICA4+) via the host Jack I get no connection to the Mac App.
The connection to the iPad (via ICA4+) is working sometimes. But I have to open the App before any other App (like Keystage or AUM). And even switching back from any Application to ME stops the connection and sometimes crashes the other App (especially KeyStage)
I'm using iPadOS 15.02 and have disabled Keyboard in the Class Comliance (using MIDI + Control Interface)

Use the control application to disable the keyboard interface in the firmware section.

I already did this (as mentioned in my post)

I see. It was early in the morning for me. I'll test tomorrow.

I just tested a here with a Quattro plugged into the Host Port of my iConnectMIDI4+ and all is good on using iOS 14.6.

I updated to iOS 15.1 and all is still good. I did find a few bugs however, and I've updated the iOS Control Application. It should be available in a couple of days.
