Make 1 Mouse Wheel Click = 0.5db on Mac

How can I make 1 Mouse Scroll Wheel click to = 0.5db, no matter how fast or slow I scroll ? on Mac.
for changing automation , volume, values, and EQ values.

You can’t.

this is very bad of cubase , terrible actually

I am not sure why this is bad for the general user.
0.5dB is just an arbitrary number that looks good in the decimal system. From a audio engineering point of view 0.6dB would probably make more sense.
And then a change of 0.6dB has a higher impact of perceived loudness when it is applied to high levels compared lower levels.

Cubase’s current system makes much more sense.
