1. (Only in Linux and macOS) Install socat if it is not already installed: sudo apt install socat in Debian based distros or brew install socat in macOS Homebrew
2. (Only in Linux and macOS) Install mpv media player: sudo apt install mpv in Debian based distros or brew install --cask mpv in macOS Homebrew.
3. (Only in Windows) Install latest PowerShell here: https://github.com/PowerShell/PowerShell#get-powershell
4. Download the latest repo release from here and unzip it (you can also perform git clone if you have git installed)
5. Copy the mpvplaytime folder to your MuseScore plugins folder (see here for more info)
6. Restart MuseScore 3 (only MuseScore 3 is supported until MuseScore 4 is compatible with QProcess calls in plugins API)
7. Set a shortcut, as Alt+D (or Cmd+D in macOS) for the mpvplaytime plugin in Plugins -> Manage Plugins menu.
8. (Only in Linux and macOS) Run unix-mpv-setup.sh script to setup the mpv player (see the script for more info).

1. Open a score in MuseScore 3
2. Open an audio performance in MPV player. For Windows users, use the already bundled mpv.exe in the mpvplaytime/mpv-*-x86_64 folder. For Linux and macOS users, use the mpv command in the terminal or in the apps dashboard (Launchpad).
3. Toggle duration display in the player by pressing Shift + O keys (not needed if you are using mpv in a terminal).
4. Follow along the score in MuseScore while listening the real performance and tag the time you want to mark with Alt+D (or Cmd+D in macOS)

• For some reason, Linux is not able to create the text in the score using the cursor class. A workaround is being researched.
• The plugin is not able to detect if the performance is being played in MPV or not. So, if you press the shortcut while the performance is not being played, the plugin will still create an empty text in the score. A workaround is being researched.
