Note

The Piano Sheet allows you to easily share songs to other people, or for yourself to try. You can change the delimiter as well as the split size, and spacing. This will use the current keyboard layout that you have chosen.
A queue allows you to play songs without having to open or delete a song or file.
You can set the player to light mode/dark mode and change its accent color.
MIDI files (.mid) are a set of instructions that play various instruments on what are called tracks. You can enable specific tracks that you want it to play. It converts the notes on the track into keyboard inputs for the game. Currently it is tuned to C major.
The short answer is that it's uncertain. Use it at your own risk. Do not play songs that will spam the keyboard, listen to the MIDI file first and make sure to play only one instrument so that the tool doesn't spam keyboard inputs.
