So much ado about nothing..
Line6 explains in all their commercials, their website, their ads and in evrey music mag that the AmpliFi has to be controlled with an app.
Better said, you bought the wrong device! How clear do you want to have it????
"Control it with an app" is nearly written all over the Line 6 AmpliFi place! If you wanna control stuff with your computer, get one of their other stuff (Spider Amps, POD series etc.).
