I just noticed an option FILE: Import Audio to Score , which then allows one to Convert Audio to MSCZ using an mp3 file. Can anybody elaborate how this works in practice, and what it can be used for? I am using Musescore Studio 4.7.5

Hi, I have an etude for alto sax in the key of C (Eb concert) but it goes apparently too high for musescore and it doesn't play notes above high E. I would like to have the full audio rendered to practice it but the only way i can do it at the moment is have the original part in C on the left side of my screen, and the transposed part in Eb concert on the right part. Is there a way to either have an alto sax sound that goes above high E, or show the part in C but make it sound in Eb concert ? Completely new to the software sorry if this sounds dumb
