Replace Instrument in Digital Song

What I am wondering is if there is a way to use this program to replace the instrument used in a digital song. This song is not my own, but I am interested in replacing the piano with uilleann pipes or the like. Will this software allow me to do this? If not, does anyone know of a software that will allow me to do this? Also, I know nothing about editing music, but am a quick study. Any information would be great!

If the instrument is combined with other instruments in the song, then no. We can’t split apart a song into individual instruments.
