After assigning an app, its icon and name will appear in the input slot. Tap the icon to switch to the app.
From here you can remotely record the generator's audio into Cubasis. Some generator apps can also act as instruments; however, they may only be connected once.
Note
Monitoring must be enabled on Inter-App audio tracks. Background Audio must be enabled for both apps.
