[Looking for help with melodies]

Ahh killer, that answered my question perfectly. I figured arpeggiations were used, and I suppose arpeggiated chords too.

[Looking for help with melodies]

Okay, I'm not asking "how to make this melody", I wanna know how melodies like this one are structured and I can't seem to figure it out correctly

The melody comes in @ 4:32

 

I know it's a resonant saw with delay @ filter cutoff, but how are these notes arranged? Are these done using 1/16th notes, 1/32 notes?

 

I know scales and stuff so that's not a problem, but also how would these look like in a scale would they be all strecthed out across an entire octave or grouped closely together?

 

All help is appreciated
