Thanks for the report! I am glad someone is using this new version of the SeqXX line of apps. I'm still dealing with outside stuff due to moving, but will hopefully be able to do more work on it as we get settled in. Thanks again!

Finally go around to this one. We had to disable mouse-wheel scrolling for this reason: In qseqkeys, we did not want the scroll wheel to accidentally scroll the piano keys vertically. Same for qscrollmaster, qseqeditframe64, except that we note wheelEvent() is not called for some reason. One way around this issue might be to somehow pass child scrolling up to the qscrollmaster class, e.g. via a signal.

For now, we have mitigated this issue by enabling the scroll wheel in the pattern and song piano rolls, and disabled it in qseqdata, qseqtime, qstriggereditor, qperfnames, and qpertime.

So, the scroll wheel will work in the large piano rolls, but not in the smaller panes at the top, bottom, or left side of the piano roll. This fix is currently in the portfix branch, and will be in master for version 0.99.4.

I will eventually look into emitting a scroll signal.

Another thing to look into for this issue is implement horizontal and vertical zoom via the scroll wheel. I assume that would require using Shift to modify the scroll wheel action. In the meantime, there are keystrokes in the piano rolls to effect zoom in both directions. Stay tuned.

Sorry to say, I'm no longer into the seq66.

I think this is as good as it's gonna get. Click the piano roll to use the scrolling wheels.
