I try to make it kinda simple. For some reason, a Rebound track by certain user's of here's (

) kinda opened me to this approach.

As also Lastisland said. Saw, detune, load of reverb. I tweak harmonies at this point and then, when it needs some more harmonics I start to add some richer layers, but just very carefuly. Huge granular stuff is fun, but I feel like, especially with Omnisphere being so popular now, it gets kinda overused. Dunno.
