Answer 1

Firstly, activate developer seetings in your device, make sure to connect your device to the computer by a USB, in the developer settings enable "USB Debugging", then you should be able to run the app on your device. If that doesn't work do this:

1. Go to Developer options
2. Under Networking, tap on Select USB Configuration
3. Select MIDI device
