Karaoke, Allure of the Seas

Hi all! I'm sailing on Allure this June and was wondering if the karaoke system allows for a song's key to be changed up or down.

Hello, I have not personally been on the Allure, but on the ships that I have been on, their machines did have key changers.

I was wondering if they will allow you to bring your own karaoke disks? Most of the songs I sing are not offered on cruis ships. I fear the answer will be no because almost everyone has gone digital.
