Q: Can I change the music volume?

A: You can change the music volume by typing /setvolume and a value from 0-100. 0 is "off", 100 is the loudest. So for example if you wanted the music to be half volume, you would type /setvolume 50 We do not recommend using /setvolume to turn the music off, you should use the music toggle button located in your options menu (at the bottom right hand part of the screen).
