The crash is easily reproducible:
- Select the line tool
- Select a CC event from the filter menu on the right
- Draw a line of new CC events that ends at the far left of the computer screen, i.e. before the start of the song.
- The program will hard crash.
This won't happen with Velocity, but it will happen with just about every other event, including tempo, pitchbend, etc - basically any option that means a new event gets placed.
This also doesn't occur with the piano roll window itself if you place *notes* using the line tool - only with the controller pane.
