Being able to choose a monochromatic or other color schemes and let S1 automatically add the colors to tracks and channels according to their posistion in the arranger and mixer.
For instance lets say you could choose a monochromatic greyscale scheme youll get a gradient greyscale tracks (light to dark or dark to light)) from top to bottom and left to right (in the mixer). This way its more consistent and you dont have to pick a color yourself for each time you add something.
