Airy Sine Lead

Hi guys,br
br
I’m trying to recreate a synth lead from the tracks below. It’s a very high pitched airy, resonate sound, almost like a whistle.br
br
You can hear it at 3:30-3:45 in Strobe - Liebe (Orjan Nilsen Remix) [url]Strobe - Liebe (Orjan Nilsen Remix) - YouTube
br
And 3:05-3:07 in DJ Borra - Until I Fall Asleep br

br
It sounds like two oscillators, one sine and the other noise? Can anyone help me here?br
br
Thanks!br
Sean
