Something that used to work in 8.5 and doesn't in X3 are the keyboard shortcuts to note, velocity and length
In the PVR I highlight some events, then type alt p v to effect their velocity.
In X3 the tracks disappear! The V is swallowed by the track visibility. To make it work I have to grab the mouse, switch focus to X3 main window and then type the shortcut. This adds overhead to a keyboard shortcut and somewhat defeats the purpose.
Has this just moved on the keyboard? I can get the quantitize menu with shift-Q. OK How about N and V?
I just searched through the Help:Keyboard Shortcuts and I couldn't find anything for the Note or Velocity menus
