I've released Localizer 1.1.1, due to an embarrassing bug. The vertical offset was bound to the coarse horizontal offset control. This is now fixed. Please download the new version here: https://surfdrive.surf.nl/files/index.php/s/ehapBNvfCS6zw35
Note: There is an incompatibility with the AudioUnit (AU) plugin. It won't work. I know about it and will release a 1.1.2 with this fixed soon.
