Hey, just purchased Cider. Can't see the button to enable apple music Sing feature. How does one enable it? Can't find it in the settings too.

did   u able to find it? I am also searching for that 

Hello, Kai here! 

Unfortunately, the Apple Music Sing implementation in Cider is only for the visual part of the lyrics, and not for the Vocal Attenuation. Vocal Attenuation (Adjustment of the volume of Vocals) is locked behind a combination of on-device and cloud machine learning algorithms, and is encrypted therefore not accessible by Cider. Sorry for any confusion that might've caused.

Thanks. I now understand
