Hi Rusty
Sometimes you just get lucky... I purchased a program that analyses chords from an Mp3 about 10 years ago. I think it cost about $10. Reviews I read on it at the time were that most people thought it was complete rubbish. I love it and I use it every single day. I also use a karaoke maker every day. This one cost $40. Then there are also free tools
www.simplechordpro.com and Canva that I use every day.
Are these the best tools for the job? I have no idea
People will use what works for them and who are we to judge?
In my opinion, if this crowd gets their marketing right, this tool could work for many people who don't have any experience making music and just want to make a song and a video and share it on social media. If it works and more people are able to make music then more power to them.
I do a lot of online education on Band-in-a-Box and I cannot tell you how many of my clients have simply given up because it is too complex.
