More creative, but still tapping -0db mercilessly.
FL comes with a limiter plugin, please learn how to use it.
At the beginning, the high-passed synth was a bit too buzzy, it was annoying almost. Try playing with band-passes? You might love them.
The composition was absolutely beautiful though. I would really love to do a version of this song, if you'd be cool with that.
You can have ago if you want, I douse FL limiter. i tweak it so I can get as much volume as I can. For me there is no clipping due to it being 'too loud' so i leave it be.
Once I'm back at my desktop I can provide project files.
I love it, great work! :D
Please contact me if you would like to use this in a project. We can discuss the details.
