It’s time to get away from some of the traditional skeuomorphism of the analog style mixing GUI.
I would like to see a grid with a dot for each channel so that the panning and volume can be controlled by moving the dots from left to right , back to front. The reverb and transients could also be controlled this way. Look at the VSL MIR reverb grid as an illustration of how this can be done. Additionally and unlike MIR, it should do full animation of automated moves.
It makes so much more sense to pan this way because you can see where everything is at once.
It would probably require a new mixer (in addition to, not to replace the mixer).
