Feel free to steal that hypersaw. I'm suprised it turned out so well.
Basically, you have 4 saw generators plugged into their own vibratos. There is the base note, the octave below, two octaves below, and a reduced-volume octave above.
Each vibrato is at a different frequency and they aren't particularly strong. I've decided to make the base note the weakest vibrato. This seems to work well; the values I used for amplitude were 8,5,8,11 (highest to lowest).
Of course, if you can synth an excellent open hihat / crash / snare / tom, please let me know.
