Flow 8 iOS app - 200ms MAIN OUT DELAY on prefs page in editor - what is it?

New

In the iOS Flow 8 editing app on the preferences page (when you scroll down a little) there is a square box with MIDI DUMP in it, but next to that is  MAIN OUT DELAY : 200ms. 


Can someone explain what this is, what it's for and if it is user adjustable?


 


Also, can the sample rate be altered from 48khz to 44khz?


 


Thanks
