I use a software called Midimittr to use my iPad with TouchOSC as a generic remote. I use this instead of the usual WiFi because with this software I can use the USB cable and it’s WAY faster.
The only thing that bugs me a lot is that every time I reboot my machine and open cubase, I have to manually select the MIDI input and MIDI output for this device. The weird thing is that I have only to select it once after each boot. If I close and open Cubase it will be remembered but if I reboot my machine and open Cubase I have to select it again.
I’m on a Mac Mojave (I’ve also tested on High Sierra) and Cubase 10.5.20 (also happens on 10)
Anyone have an Idea of what should be the problem ?
