i've always wondered how they create those long sustained high res sweeps i've heard on numerous tracks?? sorry if theres already a similar tread

i think they usually use synthesizers.

put a lowpass filter on a pad which you are using in your track, automate it so the cutoff starts off lower and goes higher, that gives you the whoosh sound, apply Lfos to the cutoff and automate the rate so it speeds up or slows down, automate the depth and resonance so it sounds more/less prominant. You can also just automate the cutoff lfo resonance within your vsti. do this on more then one pad but change when they start moving upwards, maybe one without the lfo you can also use a high pass filter maybe on the second pad, put distortion on it etc, mess it up like.

Im sure there are more techniques to this but thats the basic one i use.

10x very much for the reply mate
