Horizontal Scrolling inverted / opposite between Windows and Mac

Thanks for the reply. I went ahead and installed X-Mouse and followed the setup advice posted by Roger_Cabo_1000 here:

Unfortunately that does change the mouse wheel behaviour in EZD as well. But yeah, if I could configure X-Mouse so that it only affects the main tracks window and the piano roll window, that would be ideal. I’ll try again tomorrow. Do you remember anything regarding how you went about specifying which windows in Cubase for X-Mouse to affect?
