The [Responds to Master Gain] option does not seem to behave correctly on input ports.
The option does seem to work correctly for output ports.
If I turn off (de-select) [Responds to Master Gain] (in Options) for a input port, it is still being controlled by the [Master Input Gain] slider (upper right of the main screen). I would expect that the [Master Input Gain] should have no effect on the port if the [Responds to Master Gain] option for that port is turned off.
The same actions for an output port works as expected: [Master Output Gain] affects the Gain if and only if the [Responds to Master Gain] is on (selected) for that output port.
Win10x64, Build 3694 (yes, I’m becoming painfully aware of how outdated my version is …)
I am using the Monitor page to monitor each of these situations.
I do hope I’m understanding how these controls are supposed to work …
