MUSYNX is a rhythm game released for the Nintendo Switch by PM Studios. It features over 90 songs (largely from Chinese artists) with more songs getting added as free updates.
The game utilizes a note highway with the game's inputs being listed in each row. The player has to hit the buttons as the notes hit the white strip before the end with greater score for the most accurate inputs. The default mode is 4K and only has 4 keys with the option to play with 6 keys as 6K. The area surrounding the note highway has different animations depending on the song's category. The player can customize the speed of the notes coming down the highway and how much of the song is affected by the player's performance. The player can also manually adjust the note syncing.
