If you try to set the RC mode via "custom" parameter too, RC mode will unavoidably appear in the command-line twice – as the program clearly says: "custom" parameters are not validated and you use them at your own risk.

Most CLI tools will allow to specify even "conflicting" switches, in which case simply the last option on the command-line will take effect. This way you can easily "override" options already set by the generated command-line.

But: It appears that QAAC does more "pedantic" checking and won't allow to "override" the already-set RC mode.

There is no easy solution for this, because we would need figure out any possible combination of "conflicting" options. And, if a "conflicting" option was detected, remove that option from the generated command-line...

(Maintaining a list of potentially "conflicting" options – for every supported encoder – would be a lot of work. Just to enable a use-case that was never really intended)
Thanks for the explanation. So in short, there is no way of using a custom-defined bitrate or quality level for AAC in LameXP?

Would it be possible in that case to provide an option somehow tweak the TVBR slider so that we have more granular control? (Maybe an "advanced" slider activated by a checkbox, that allows the user to move up and down in increments of 1). That's the only solution I can think of for this but I don't know how feasible it would be to implement.

Other software allows you to select the TVBR quality level in increments of one right from the GUI, it's just that they don't have any easy was of importing your whole library in one go like LameXP does.
