I am not a stringed instrument player, they have confounded me for decades (honestly its a cognitive disconnect). But with this tool I finally feel in command. I tell it what I want to play and how I want to play it and it shows me how to accomplish that goal. I tell it that I want to see what that song would look like on a completely different instrument or tuning and it shows me... Fantastic. The app itself is deep and complex and could benefit from some simplification in the UI. If I had not been someone who has been using computers for music since the 80s I might have been a bit more lost. As it turned out, I still found it challenging. The developer needs better documentation and a good set of how to movies right away. To avoid people getting frustrated. I did have a problem with the app not showing me common fingerings of basic mandolin and ukulele chords but I emailed the developer and got a response that was honest and clear the same day. I am confident he is actively working on this project and dedicated to making it better.
Good thing too, because it is great. If this had been available 30 years ago I would be calling myself a string player today.
