Solo / Mute for individual instrument tracks

As already requested in solo feature request, I think it would really helpful to make individual tracks play in solo. Additionally, when using a similar band for different sections/parts, but with slightly different sound settings (e.g. fills), it would be helpful to solo individual instrument tracks for the whole song. I don’t know if this is easily possible within the current architecture, but it would a great feature that would ease usage a lot!
