Hi Smitty0306,
Thank you for your message.
The apps run in a free demo mode, unless being unlocked via connecting a compatible device (such as the UR44C) with the iPad. Cubasis LE 2 and 3 are compact versions of Cubasis, which come with a reduced feature set compared to the full app.
Here you can find the list of the features available in Cubasis LE 3: Compare the Versions of Cubasis | Steinberg
Hope that helps!
Best, Lars
