On this post from KSHMR and Bassjackers you can see,that they used the "FabFilter Saturn Saturation and Disortion" Plugin and wich plugins they used for the Lead sound from their collaboration track "Memories".
He shows it at 5:41 while explaining a mixing chain from his song "Broadcast (feat. Shadient)".
"I didn't do the distortion. Morgan (Shadient) did this and I don't really know how to use FabFilter Saturn. So that's just there as it is." (Quote from the same video; 6:29)
On [Splice.com](https://splice.com/tiesto/tiesto-kshmr-secrets-drop), KSHMR provides information about his track "Secrets," created with [Tiesto](http://equipboard.com/pros/tiesto), including the plugins used. FabFilter Saturn is one of those plugins.
