Is there a way to change the playing music volume? I would like to make music fade in/out transitions between different songs, like when a boss fight is approaching.

yes, you can change channel volume in the Sound Registers  using 'poke' api https://github.com/nesbox/tic....

Also, I'm going to add Fade effect to the Music Editor

Oh, nice! Thanks!

Hi ! I know it's a bit old but I also need to change the volume and I don't understand how I can change it by poking. I would be very thankful if you could give us an example code.
Thanks !
