A software that can simulate various musical instruments, including multiple instruments and built-in recorders, custom sheet music, etc. After the built-in recorder is turned on, the recorded audio can be directly imported to the system desk --provided that at least a few MB of space is reserved on your computer desktop-- At the same time, in the custom mode, import audio for each button to make it your special instrument. In traditional instruments, you can use game supported formats to write sheet music to make the instrument play automatically!
