MIDI not working / works in AUM


I have a Digitakt hooked up to the iPad via USB, in AUM I can send MIDI data from the keystep to the Digitakt and it works.

In Cubasis 3, I set up a MIDI channel and configure the input to be keystep and the output to be the Digitakt, I am on the correct listening channel on the digitakt but it is not working. I can however, load up an auv3 instrument on the same MIDI track in Cubasis and it works fine. Has anyone else ran into this issue?
