That detuned saw lead? can be made in most synths
Do you use massive?
OSC1 - Saw wave, OSC2 Square wave
Go into voicing and set to monophonic, Set unison to 3 and move the pitch cutoff slider along a little bit to taste.
Go into osc and increase the glide time a little.
Use daft filter in Filter1 and bring the cutoff down abit to get rid of abit of that high end
Should get you on the right track and give you the backbone of the sound your after. You will want to tweak it and spice it up from there
