It's official GT-8 Fx Floorboard is discontinued.
I finally sold my Boss GT-8 today. I had stopped using it a while ago and so stopped the development of the GT-8 Fx Floorboard software. Collin, a developer who has started to work on other GT versions, will take over the project and will continue to work on it. From my side it is now officially discontinued. From now on you can go here for the latest and greatest: GTx FxFloorBoard
