This one has been killing me for too long now, the sound can be heard throughout the track, but it can be heard alone at the end at 6:47, it's some kind of random electric madness, how can this be achieved ?
saw wave + bandpass filter, with high resonance, short amp. envelope times, play with the filter and the filter envelopes. add distortion to your liking.
then add any fx you might want. in this track i hear both reverb and delay.
it also sounds really good with synced oscillators or on a fm synth.
the trick with these sounds are to filter the patterns "harmonically" to create a catchier/psychedelic lead or melody.
