This is a bit hard to explain in words, but it’s been happening since 8.5 and is still happening in 9. It affects automation editing when dragging automation points, and it’s a major bug. Pay attention to the automation points that are NOT selected but are jumping in value.
- Create three or more automation nodes, at different or the same values.
- Move two of the nodes together vertically up or down (Not using the trim tool, but moving one of the actual automation nodes) and you’ll see the closest nodes they’re connected to snap to the same position as the one you’re moving.
Please WATCH THIS GIF that I made, as it does a better job of explaining it:
