Freeware Sweep/fx Generator-type-thing?, Jet fly-bys, lasers, etc? Options

[Turner]

Hi -

I'm looking for some sort of freeware (or shareware, I guess, if there's a demo and it's really good) to generate sound effects such as laser sweeps, jet plane fly-bys, wind, etc...

Any leads appreciated!

thx
Andrew

With out a doubt, the best free v-synth capable of doing anything one can imagane is Crystal .
