Isn't that what MIDI did for music?
The next best composer might not know a single instrument, but make great music every day.
The intention guides the result, not limited by the actions.
It's essentially a sampler, locked in a single chord progression. It can be used as "an instrument". It is very simple and intuitive to use.
If it had free chord choice, it would br harder and less intuitive. However, it would make the user think about what chord progressions really are. Closer to what an estabilished instrument that stood the test of time is.
Can you have both? A simple intuitive instrument that can play all that a "hard" instrument can, requiring no practice or cognition? (rethorical)
My comment deals on this kind of treshold. An instrument that both a "born talented musician" and "someone who tried very hard" can play in equal terms is a very good sweet spot in terms of inclusion and equality.

MIDI doesn't contribute to that. We had musical notation before we had computers.
