Automation curve segment selection error

Jordi Moragues · started 2019-03-27 17:09 · updated 2019-03-27 18:21

When multi-selecting two segments on an automation curve which are themselves separated by just one segment, the middle segment is also selected. If the selected segments are separated by more than one segment, only the clicked segments will be selected. I'd expect this behaviour regardless of how many segments separate the selected ones.

Steps to reproduce:

Create an automation region and define five or six key-frames.

Click a segment (line between two key-frames). It will be selected.

Shift+click another segment more than one segment apart from the selected one. Only the clicked segment is added to the selection.

Deselect all segments and click on a segment again to select it.

Shift+click another segment one segment apart from the selected one. The clicked segment plus the one in between this and the first selected one are added to the selection.

I was playing around with changing the curvature of several segments simultaneously (that feature is seriously good) and noticed this. I understand the problem. The only workaround I can find for now is to use the razor tool to cut the segment in between the ones you want to select, edit them, then delete the mid key frame. I have no idea if this might be a solution or if it complicates things more, but perhaps the app could have invisible key frames at the midpoint of each segment, inaccessible to the user, which could be used to discriminate contiguous segments?

It seems to be working perfectly now. Thanks!
