Hi,
something like the following setup is possible:
- Connect an external keyboard to your iPad and use it to play Cubasis’ external sounds, for instance the piano. You can do this via USB or MIDI.
- Sing through the built-in Microphone and listen to it with effects using headphones.
You can also use compatible Audio- and/or MIDI-Interfaces. You can find a list of compatible devices on the product page (Cubasis: Music Creation App for iOS & Android | Steinberg). Further information about what you can do with Cubasis is available in the manual (http://www.steinberg.net/fileadmin/files/PRODUCTS/Apps/Cubasis/Cubasis.pdf).
If you have any further questions about Cubasis let me know.
Kind regards,
Frieder
