So I've had LMMS for about a week now and I'm working on my first song, but when i try to make an automation track, you have to press control on a control knob and drag it to the automation track for it to work, but whenever i press control, it dose nothing (the key isn't broken) and I've seen a good amount of videos on how to do automation, but pressing control on my mac just won't do it. Help?
