The relay attenuator plugin V1.3.0 has a setting to switch the volume range from the default 0 to 100, to 0 to 63; that makes great sense since the attenuator has a 64 dB range. However, switching it has no affect on the UI; the UI still shows 0 to 100. For those of us who want to control recording level in exact dB steps, this is a big problem.
In addition, the plugin reports an error on installation (Detail: Error), and also if you try to uninstall it. Uninstall doesn’t work; you click ‘Uninstall’, get the error, and the plugin is still installed.
