Did anybody see the new GarageBand IOS update today?

Facial control via your iphone X for controlling synth or effects parameters.  Pretty cool.
What CC# is my amp attack env?  Oh wait just stick my tongue out more.
My left nostril does a great half cocked wah.
 
BandLab is prime for that sort of innovation too.
 
full release notes for GarageBand for iOS version 2.3.3:
