Thanks Warren - It's a real compliment to hear that I was able to capture your attention when the electronic genre is not usually your bag! Thanks for giving it the time and so glad you enjoyed it. I think it really comes to life set to the NASA video too, the footage is just perfect for the sound. As suggested I have added this to the original post.
Wookiee - Again, thanks for listening and glad you liked it. As for synths, I used the following:
Rapture Pro - 3 instances
Z3TA+2 - 4 instances
Camel audio Alchemy - 2 instances
Dimension pro - 1 instance
Session drummer 3 - 1 instance
Plus a handful of samples from my ever growing "boom and sweeps" folder and a few additional drum samples.
Happy to go into more detail if you are interested.
