how do i get those high frequency moving sounds that fred v and grafix use a lot on tracks like this http://www.youtube.com/watch?v=fasKZeOVPnQ i dnt know how else to explain it, doesn't sound like a synth maybe a sample with an lfo in kontakt? safe
Find an interesting pad synth with some modulation and high frequency content. Try using different filters like bandpass, comb, and high or low pass on the pad. Use about two or more of these filters in sequence so ones modulating the other with higher lfo settings. This will keep things interesting as the sound will change and evolve. Good luck.
