Automation in music is the real distinction between a professional sound and an amateur sound. Knowing how to properly adjust your automation lines takes time and practice. I've created a tutorial video to help you get started. This is a basic Pro Tools 101 video for audio production beginners. However, I usually learn something new from every video that I watch, so this may be a good place to start for everyone that wants to know more about using automation in Pro Tools.
You can also check out my YouTube channel and find many other helpful videos on how to record, mix, master, and produce in Pro Tools.
