White Noise

I want to make white noise effect to back up sounds and to make it rising and falling.I think it is kind of essential effect so if someone can help.I am using only included VST synths and plug ins.Thanks.

Ok, to make things easy, there are tons of vids on the Tube how to do this.
Basically, take yer synth, put on the noise osc and start with the filter full open.
Automate the filter to make a gradual highcut ( or the other way around) or use an lfo to do this.
Record this and put it in a folder called Rises or Falls and access it via the Mediabay.
