Hi Richard65,
Cubasis LE is the compact version of Cubasis.
The app runs in demo mode when being downloaded from the AppStore.
To unlock its dedicated LE feature set, a supported hardware device is required, as seen on the Cubasis LE website.
I’d suppose the iTrack Dock will work fine with Cubasis, as stated by Focusrite.
However the device is not supported to unlock Cubasis LE from demo mode.
Hope that helps.
Best,
Lars
