As people also pointed out in that thread, some classical instruments like church organs have exactly the same problem.

Look at this one for instance: https://en.m.wikipedia.org/wiki/Organ_console#/media/File%3A... It has 522 draw knobs and 796 total controls for the musician to use. How do you play something on this organ to sound exactly like another organ?
