Gerritt explained to me what I was doing wrong.
I had noticed that changing the pitch bend range via RPN events works as it should.

With further testing I’ve found that a viable workaround is to force new settings via RPN events.
Still, the default is not ±2 semitones as per GM specifications.
Still, I can’t change it through the macro or zone editors.

As for making it so the controls in the Macros would work again…
In the options tab, there is a setting for accepting or ignoring RPN events. Disable those if you want to control pitch bend range directly from the HALion UI, Macro, or via custom MIDI or VST events.
