How do I make clicks on CC4 info without the line jumping?

Hello,

I’m trying to edit the CC4 information on a drum track. When I click on the horizontal line to make an edit, unless I get lucky, the horizontal CC4 data after the click moves. See attached screenshot (everything after the far right entry moved down and then I have to mess with it to get it back to where it was).

Is there a key modifier to make a click entry on the CC4 horizontal data line without moving what’s already there? I can’t afford for my workflow to be hindered like this.

Thank you in advance.

Hi,

Disable Snap to Grid (Key Command J), please.
