Have you tried using Logitech's SetPoint Manager to set the app-specific roles for your controls? I don't have a horizontal scroll wheel mouse so your settings will be different than my screen capture, but you can try adding PD14 and see if you can use the H wheel for anything useful:


Hopefully, someone who does have a similar mouse and PD17 will post if there's any native support built in.

Ha I hadn't noticed that! In PD17, the wheel scrolls vertically in the library or FX rooms when there's too much content to fit in a single window, but on the timeline it does scroll horizontally. That's a nice improvement

PD17 - scrolls left and right only on the timeline with the scroll bar only if the line with the scroll bar is first clicked on mine.

Mine scrolls horizontally without clicking first as long as the cursor is hovering over the timeline and there's already content there (meaning whenever a horizontal scroll bar is present). It also scrolls vertically when hovering over a library/room as long as a vertical scroll bar is present, even without clicking.

It would be nice to hear from anyone who has a horizontal scroll wheel to see what (if anything) happens in PD17 when that's used.

I haven't tried that software, but I have tried Logitech's 'Options' software, which they recommend for this mouse. Unfortunately it dosn't do anything to set it specifically to PD14.

It seems I may have to take the plunge and upgrade to find out. I do like the software though so it'll probably be worth it either way.
So I'll check back in a bit when I've messed with it.

Nope no good, the horizontal scroll wheel doesn't scroll the timeline in PD17, it just does nothing for some reason.

I guess I can just hope that they implement that functionality one day.

Two of us can scroll horizontally so it’s perhaps mouse-specific.

Right, it's the vertical wheel that scrolls the timeline in PD17.

I'm pretty sure that apps have to be built with the internal code to utilize a second mouse wheel, and since they're kind of a niche item, it may be hard to find many programs that support them.

Try first to click (left click) anywhere in the video tracks area and then scroll with vertical scroll. It causes (in my PD16) the time line to scroll horizontally (mouse Logitech M310, G700)
