It’s confusing when just starting out, I explain how it all works below. So if you’ve tried to create an automation clip, then adjust the parameter differently at the beginning of the automation clip, you’ll notice it defaults to what you originally created, not your new adjusted value. In addition, how FL Studio creates automation clips is it literally takes a snapshot of your parameter at that moment in time.
Sometimes you’ll have to use VST2 versions if that’s the case! Make sure to test that VST3 does not crash FL Studio. You have to go Tools -> Last tweaked -> Create automation clip.) These allow you to right-click inside the VST itself so you can copy values, create automation clips, and treat the third-party plugin as if it were a native FL Studio plugin! (VST2 versions do not allow you to create automation clips through right-clicking. I’d highly recommend using VST3 versions of your plugins with FL Studio.
