How Do I Export MIDI Tracks?

I have a number of tracks half done in S1, and I would like to transfer them for finishing in Cubase. How do I export instrument/MIDI tracks in S1 so that I can place them into instrument tracks in another DAW. The only options for stems/track/chael exports that S1 appears to give me are ones that bounce/render everything to audio. I don't want to export my instrument tracks as audio though, I want to export each instrument track as a MIDI file. How do I do this in S1? Can I do this in S1?
