Using trance supersynth Sylenth VST to create a supersaw

Supersaws are based upon using sawtooth oscillators – what gives them their distinct sound is the method of detuning the sawtooth oscillators against each other.
This detuning takes place over a set internal of time to create its iconic noise. Although this video demonstrates the principal using Sylenth – any synth can be used to create this trademark Trance synth sound.
