I've never been able to do this, and very much wanted to.
That video is from the original Spark, not Spark 2.
A workaround would be to set your DAW to record MIDI out from Spark 2. That's what I do, and it works great. ... You then have to remember to turn OFF "Host," otherwise when you start playback in your DAW it will also start playing the pattern in Spark itself, along with the recorded MIDI.
