Then why bother posting in the first place??
well.... since you insisted...
I'm a big fan of using presets to get you started, but I rarely keep the preset settings. One button or one preset or even one hundred presets just doesn't get the job done in many cases.
Oh yeah, for many, this is the Holy Grail discovered in the music world, because of one reason or another. Depending on your POV, one button may be perfectly fine but to another person, maybe not.
I've advocated in the past that anyone serious about mixing music should take the time to learn what the various aspects of mastering involve. Take the time to learn about compressors and why you need one and what settings you need to use and what's happening when you adjust the threshold or the release. Learn about the EQ and how to properly apply that as well as reverb. And learn the difference between the limiter and the compressor so they can be properly applied. Many folks who use these "one button" solutions, I would wager to say, don't take the time to study and understand those things. Instead, they pop in the preset, say to themselves that it sounds better than their original tracks and leave it at that, calling it done. And like I said, if that's how you feel and how you work, hey, all the best wishes in the world for your continued success.
It's when you take the time to dig into the depths of the plugs and learn what's going on under the hood, that you gain a huge step forward in in your mastering and mixing skills.
