Hi Hartmut,
Cubasis supports both IAA audio and IAA Midi.
It always depends on the app instrument/effect manufacturer, what IAA type is supported.
IAA Midi
- This option works for MIDI tracks (and effects)
- Tap the instrument icon in the track list and browse the Inter-App Audio folder
- Pick an IAA Midi capable instrument from the list
IAA Audio
- This option works for audio tracks
- Open the routing tab in the inspector
- Tap on Mono input to open the Audio Inputs selection
- Tap the “Inter-App” button
- Pick an IAA audio capable instrument from the list
Please also have a look at the “Limitations of Inter-App Audio” article available here:
Best,
Lars
