Thanks rikrak - that’s very useful, up until now I had been copying only track trigs, patterns and parts. It would be cool if there was a way to copy ONLY the track settings though, without the trigs! Good enough though 
Can I route the audio inputs ONLY to the Cue outputs, without using a Thru machine? I can Cue the inputs, but they appear to be (in the headphones anyway) going through the master as well.
Really appreciate the advice.
