GT-3 Manager 1.2.0 for Windows can now be downloaded from the GT-3 page.
There are three editions: a dual 32-/64-bit installer, a 32-bit portable and a 64-bit portable.
New in the application itself are menu items opening the Master and Pedal/Assign windows.
And of course it incorporates the bug fixes from the 1.1.1 Beta 1 version.
