I just closed the app for a test and the XR18 still works and is playing 
music ;-).

Whenever I start the app it asks me if I want to transfer the current 
settings "mixer->pc" or "pc->mixer" so you can decide on whatever you 
need. And of course with "mixer->pc" you restore the last settings on 
the XR18. You can also save setups on a computer, pad and so on. Very 
useful if you have different live situations with different instrument 
setups and so on.

I also use jack_mixer in my setup to have a volume control for stuff 
that runs on my computer and goes via USB to the stereo port (channel 
17/18) on the XR18. If you wire jack_mixer (or any other Jack aware 
mixer program) accordingly you could also have a volume control without 
needing the app. You would only need the app to unmute it.

And another thing: I use external studio monitors connected to the main 
outs of the XR18. With this setup I never experienced any latency 
issues. (But again I am not a professional musician and others might 
have other experiences and see it differently.)

Hope this helps again,

Michael
