First off, thank you for the kind words on the Liszt concerto! I know this crowd appreciates the real meat and potatoes... I think my next upload will be a performance I gave of the Brahms 2nd sonata for violin and piano, with my friend from the NY phil
I will look forward to that!
To respond to perfect_pitch and others... I think I generally agree. I found/still find these videos pretty cringey, and it's unsettling to me that a single robotic midi-file upload of a great masterpiece like a Chopin ballade or Beethoven sonata can have more online views than the entire collection of great recorded interpretations COMBINED...
They are fun and novel, and that is part of the appeal. I have found in certain cases that I either prefer listening to a proper interpretation, or a robotic midi, with no in between, because the robotic midi can almost feel like you're reading the score and then you can put in your own emotion into it and aren't bound by the interpreter's. I don't think this is how most people view it, but it's food for thought. Another thing it does well is serve as a source of the notes for those who can't read well. I know there's some prejudice against this, but it works for some (worked for me and still does). I don't think it's fair to judge them though. In the past, it was because I was primarily an ear player and almost never read notes. I used to use midi videos to get an idea of the chords and arpeggio patterns, and maybe some tricky right hand runs or trouble spots. This helped me grasp songs very quickly, and still does. Recently, I remember someone asked me to play a Beatles song, and with synthesia I had it basically learned in 5 minutes. I know it's possible to do this with sheet music as well, but I find it harder (even though by now I've improved a bit at reading) and it takes me longer. So, it serves as an in-between, where those who like the music but can't actually read well can see the notes and follow along.
B. Could they possibly sound a little more human and express an artistic interpretation? (sort of... Check out the top channels doing this, some of them are absolutely horrendous if you want to know my real opinion).
Agreed that some of them are really bad. I don't think everyone can tell the difference, I have found that it takes a certain talent to be able to tell good playing from bad when people listen to a piece. I wouldn't say it's uncommon, but it's not universal. Once I showed someone Rosseau and Cziffra playing HR6, and said, see, obviously there's a difference! They did not get it. That was a revelation.
