airguitargb,
Never fear. You will not just figure it out, you will have fun with the unlimited ways the Helix can open your mind. Also, I can't believe I am a few months away from being 76 years old. I started the path to the Helix about 10 years ago and have not looked back. I did just trade up but that discussion is for another time.
There is a person by the name of Jason who is one of many Helix tutorial "kings" on youtube. You can start by listening to the default presets that come with the Helix. Many are named "similar" to the songs they represent.
I found that a decent 250k ohm open back headphone set like the beyerdynamic dt990 works well for in room testing for tone and sound level. datacommando is correct hat you will need to work with the sound person for your playback system. I would continually work with our soundman at least once a month when possible.
Anyway, here is Jason's Line 6 KB page and also his youtube channel. And as you search you will find more tutorial videos. You should find that your pace will quicken as you develop a self-learning path as most of us have.

You will want to focus on the Helix Floor as opposed to the Helix Stadium XL for now.
Again, have fun and enjoy the ride.
