My synth and sample collection is here!
What you have is a sound that is made from many layers of different sounds that add together to create something new. To create it will be a case of experimenting yourself, and might be a single note, or could be a sound created by laying on as many notes as you can hit at the same time. Every vsti has loads of presets, each one can be tweaked, then played. As a guide, if you have to experiment with just one vsti synth, start on programme 1, and bash a note on your music keyboard. On reed keyboards played with a mouse are useless. Mice can't hit more than one note! You might instantly reject it, or perhaps reject it after a minute or two. Then move to programme 2 and repeat. Multiply this by several synths and repeat. Even worse, the sound could be the magical combination of synth 1, programme 322 and synth 2, programme 113. I'm not joking. Creating sounds that really need to be specific to a project are always down to guided luck and knowing your equipment. I still believe that this will be a preset on a real synth, that the composer knew about and remembered.
Years ago I had to recreate a Genesis track that had a kind of elephant like drone that was the key to the entire song (no son of mine). Took me two days to find just the right sound, which I knew I had....... Somewhere!
In your case, your problem will be at your end. What sound sources do you have, because we will have different ones. As I said. Can't you just use the sound you gave us? Or do you need it to be longer, different and perhaps a different note? Keep in mind the original you like, might sound dreadful if allowed to develop and lengthen.
