When I ended up with FL, I had tried Ableton, Reason, Pro Tools, and Garageband. I was so split on which one (although not Garageband) to get, and I could make a song in all of them. FL won out because I got it as a gift. So I'm still learning it and welcome the visual changes to 12. I don't have a massive sample library or older midi equipment, so it works for me.
I get that FL is not the same FL it was years/months ago. Kind of the feeling that I get whenever Microsoft releases a new version of Windows. I would have stuck with Win98 forever if I could have and only got off XP around two years ago. Same thing happens with web browsers. Use Firefox for awhile, switch over to Chrome for a time, maybe check out Edge for the future. Maybe.
However, as a relative newbie, I am concerned about the stability issues. I've only had it crash once, and I've found that Komplete tends to work smoother for me that it did in 11. So far, so good. Are there examples of consistent crashing? What kind of conditions cause it to crash?
