The quality of the scale limiting is beyond any DAW I've used. That's great for me as someone who can't seem to memorize scales. I've heard FL Studio has a good scale limiting feature, but I can't figure it out. Ableton's is 1-3 clicks and, to me, intuitive. I wish they would steal Reaper's ability to load scales from files. Live comes with a lot, but sometimes I want to experiment.

Bitwig doesn't have it at all and they broke the paint scale->nudge to -1 workaround (which still works in Live) the last time I tried the demo.
