Hello Elantric.I recently downloaded Version 2.10 for GT-100 and I am getting Midi loop back error.Make sure Midi Thru is switched off. GT-100 does not have midi thru function and I have rescanned Midi Setup several times, removed and added the device back. Checked all versions of all hardware and software including Bosstone Studio.I have used GTFx Floorboard and it tries to initialize just as Bosstone studio but it cannot see the driver. I have installed Ver2-1 driver correctly. When I use Logic Pro X it does not recognize a midi device either.Obviously something is wrong but I cannot figure it out. Also I have uninstalled and reinstalled the driver for GT 100 and it is showing Ver 2.10. Updater message is Bin File missing . Please help .
