It would be cool if the assigned colour of each matrix track has a little presence in both the DSP chain and each track in the mixer view. So in each case, a little coloured square on the DSP vol/pan/surround device; and maybe something similarly subtle on part of the track on the mixer view. ?
yes plz. But I take it that tint or a border would be too much for you and others… so maybe there could be two colouring modes – for grown ups, and for kids!
