Hi Mike 999,
Thanks for your message.
Cubasis allows to route MIDI tracks to other app instruments and effects via Audiobus 3, Audio Unit or Inter-App Audio.
Regarding Audiobus 3 please have a look at the current Cubasis 2.1 tutorial (Audiobus is demonstrated at around 7:10 min): MIDI Editor Improvements in Cubasis 2.1 | New Features in Cubasis 2 - YouTube
We have a wide range of Cubasis tutorials available, please find them listed right here:
Hope that helps,
Lars
