Hi, Trapper. I use my guitar for composing the melody but I very seldom use them in my recordings because, after 50 years, I still play like a novice! Band in a Box completely changed my songwriting life! I use it to put in all my instruments though sometimes some friends of mine from other states and the UK who are very good musicians will play some of the tracks. My preference is to use human vocals. As AI goes, the big difference are the words "royalty-free." If you use royalty-free software like Band in a Box or online royalty-free services, you are legally safe. Copyright laws make it legally yours and you can register your songs under your copyright. Suno, like several other AI services, are in uncharted and risky territory as copyright goes because their database has works by other artists which can constitute copyright infringement. Softwares can parse the track into its parts and detect if AI was used. The Copyright Offices, many sync libraries, and the UK Songwriting Contest will not accept music produced with AI. It looks like you're very careful in these regards. But here's a kicker: when you upload your original tune into Suno, it goes into their database and other people can use it, even though it does get deconstructed. It is about as unlikely any tune of yours in whole would be stolen as an asteroid hitting Bozeman. But the fact that if someone uses deconstructed/reconstructed bits of your original work without your permission is still an infringement of copyright. There is another service that has started up: Ace Studio, that is geared more for music producers that is royalty-free, appears to have integrity, and that may be worth looking at. My personal take on AI for the so-called creation of art and composing music and lyrics to me is an insult to artists and songwriters, and is superficial and soulless. Most AI generated songs lack the genuine human touch and emotion, and are most often mediocre. This is a very good subject and worth looking into more.
