USB overdrive is one, it’s free
Nope. $20 also and worth every penny, been using it for years.
The great thing about this app is that you could have a few apps open that require different mouse customizations and as soon as you switch focus to another app, USB Overdrive automatically switches configs. I couldn’t get through the day without this in my graphics studio. And yes, I have it set up to reverse the scrolling for Cubase.
