Personally, having to listen to sheet music converted to MIDI or styles is as painful as sticking needles in my eyes! And automatic analysis of chord structure from SMF’s or sheet music is still a LONG way from being perfect.

Sheet music is an abstraction, a shorthand, an imperfect way to express the inexpressible. To hear it interpreted literally only exposes how much is lost in the desire to notate it without it becoming unreadable. Even today, there is a huge gulf between what the sheet says and what a computer can interpolate from it and still sound human. While other systems have been cracked, and computers can fool humans reading text or writing as if human, the art of music still defies machine learning so far. Maybe a few more generational leaps forward in machine learning are needed, maybe it will never come.

But put the same sheet music in front of two different pianists, both will do something different. But put it into any sheet music to MIDI translator and it will always sound the same, and nothing like either pianist!

It’s a nice pipe dream, but I think it might be easier to learn how to play from the sheet than wait for a machine to do it well!
