A Super Saw sound is just layers of Saw wave forms detuned. So turn on unison and unison detune or oscillator slop. Simple. Works with all the wave forms btw. Super Pulse, Super Triangle etc. If you need to play chords then turn unison off and detune those oscillators. Modulate Osc Slop, add differing amounts of Freq mod to all the oscillators, use the chorus effect, record the part with multiple takes and slightly detune the sound for each take.
