Yes, thanks Sidroe. I have an older X2 'complete' tute, which I had a look at last night. Seems I can do a live take over a bounce or even export, so I'm going to experiment with that. Ultimately I wanted to have a composition on one track and set up Stutter Edit on it and then use a midi track and play around with its effects...just for fun.As an aside...I was listening to Flume do his thing after the Aria's here in Australia recently and on one occasion, he pulled out the highs of the entire track and you could clearly hear the audience. He gradually brought it all back and built the sound to a climax and then brought in his next quite powerful song. Do you know how this is done? Is it a high pass filter on say the master? I have heard a number of artists do this kind of thing and its quite a powerful live excitement thing which I'd like to learn. 
If he took the highs OUT it would have been a low pass filter, not a high pass one. But while I haven't seen him perform, the Pioneer and X-One and other DJ-style mixers usually have a band pass filter instead. That means that the track also got thinner as the freqs came back up, leading to an extra climax when the bass kicks in on the new track.
You could try automating a band pass filter (e.g. the included BiFilter) on the master, but if you want to transition to a new track it's probably best to make a subgroup of one track and send all tracks and busses there, then send that subgroup buss to the master. Putting the filter on the subgroup buss means you keep the master clean which makes it easier to kick in the new track. Fading in some reverb or delay during the filter sweep can also help the effect.
