Hello, I often use strum machine as a setlist for upcoming performances. I often may have overlap of songs across multiple upcoming performances or with a song I am practicing to lead. Each instance of that song might have a different person leading it and therefore a different key. I would like to be able to pin each setlist to a specific key so that changing it elsewhere doesn’t affect the performance’s setlist. As it stands right now, I need to retain a separate copy of the setlist outside of strum machine so I can keep track of the correct key for that day.
