I’m not sure if this bug is also on macOS Cubase. I think I first noticed it when I started using it on Windows 11 in January, so it’s present in both 14 and 15, possibly 13 and earlier.
Say you open the key editor and you want to see the MIDI CC lanes that have any data. I can’t remember where is this command in menus, because I set it to F12 and forgot about it. So I just press F12. The command is called “MIDI show used controllers”. That makes all the CC controllers with any data show at the bottom like this:
If you see the scroll bars on the right, they are grayed out. If you hover the mouse pointer over either CC1 or CC11, and move the wheel, they won’t scroll up or down.
Now, you click and drag the GUI element on the center of each dividing line to make them taller (by the way, if anyone knows of a way to make all of them taller without saving a preset please let me know. Like something with the mouse wheel while pressing a modifier key kind of thing.):
As you can see, the scroll bars on the right are still grayed out and the mouse wheel won’t do anything.
Now, let’s save that as a preset:
Finally, let’s close the window, or not but load another preset, or move the height again, then let’s load the preset we just created:
As you can see, the scroll bars are now enabled, for no good reason, and if we hover inside each lane, it scrolls up and down just a little bit. That’s not the annoying thing, but rather this:
So, I do a lot of work with the key editor, and I switch between different heights all the time, because sometimes I need to work on the notes, so I need the short lanes, and when I need to work on CC1 and CC11, I need those two rather tall. And I edit a lot of automation manually, so this GUI bug really gets on my nerves. Kinda like the automation looks really nervous when this happens, shaking uncontrollably.
I hope it’s not the usual “It’s only happening to you and nobody else”. If this happened in at least Cubase Pro 14 and 15, it stands to reason that it’s a bug.
