My apologies if something like this has been discussed or is otherwise accessible, I am new to this.
I'm wondering how difficult it is to make customs for vocals only that's not pitched, ideally with the ability to turn track vocals off (multitrack?). What I'm getting at, is that I would like to make essentially karaoke tracks for Rock Band, but without any experience, I'm not sure if it's worth the time investment.
There are probably easier ways to do this, maybe I'm too attached to the Rock Band interface? I'm thinking, if everyone playing just wants to sing, I could just pop in a flash drive with more songs on it that does not include instruments.
