Using L1 Mix app on a different Pro16

Can I use my iphone with the app on a different Pro16 or will it overwrite my Pro16 remote scene settings?I want to be able to use my nephews Pro16 at his gig.He uses his T8S with it,and would leave his onboard inputs available for me to plug into as his guest player.

Hey jdpuentejr!

If you use your L1 Mix app with a second L1 Pro system, this will not affect the scene settings saved for the first system. 

Hope this helps!
