In the step sequencer of ntrack, when I try to click the plus button to add more notes to the range of notes (like vertical, as in going from A3-A4 to A3-A#5), it crashes after the second click

Hi **[Ezra\_Lehrer1](https://discussion.ntrack.com/u/ezra_lehrer1)**,

Which instrument are you controlling with the step sequencer?  
Which scale is set?  
Could you send a screenshot of the step sequencer window?
