For all of those who, like me, are waiting for the native Windows Amplifi Remote App: there is a way to run the Android version on windows and /or OS X systems. :)
Install the latest version of VirtualBox and the matching extension package (Free) and create a virtual machine running the latest version of Android that is available as x86 ISO package.
Than use you google account to get the Amplifi app from Google Play and you are all done.
There is one glitch: it might be that this is not working with your built in Bluetooth hardware and in that case you have to disable it and use a USB bluetooth dongle.
(To get ANdroid running I mainly followed the recipe given in this blog:

Thanks Vonnie!)
I currently have it running on a windows 8.1 tablet (EP121) and PC.
I was running the app uptil now on my Minix TV Box. Allthough it was rather cool to have the largest guitar tuner in the world on my 40" TV Screen, the none-portability of my TV is less practical. But for you who did not think of it directly (like me): there is a good chance that your TV Box runs Android and you canb simply ionstall the app on it.
I am also testing on a MacBook Air.(Here disabling the internal BlueTooth needs some hard core tweaking as Apple has drifted far away form it's open approach of the legendary Apple i and II for which they even supplied the source code of the bios in the manual).
And once more: dear LINE 6 People. Surprise us with a native windows app. You will not only make your windows eco system users very happy! Not only that, but you also will be rewarded soon with a huge possible increase in fanbase as your Windows 10 App will work on Windows Tablets, Windows Desktops, WIndows Phones (from cheapest of $70 to the Apple 6 rivals costing half of what Apple charges), Windows TV Boxes, WIndows Remote Controls, Windows Foot Pedals and WIndows Washing Machines for all I care, as the windows 10 kernel will be the SAME for all these devices. This also means that Windows Apps can and will not be ignored anymore by the global app makers (including you) as up til now.
So I hope that you are already on it and, in trademark Line 6 style, will surprise us unanounced with a native Windows app next week.
And if not: please get moving!
