Discussion: realistic concert piano

[Dave]

Going forward it would be a nice PhD for someone to make an AI
expressive concert player for piano.
input: midi notes + sheet music annotation
output: audio
Success: 95% can't tell the difference between real and AI, from recordings.

Things like expression and phrasing are important. So once coded up
might even be able to tune a personality, or do an exact copy of an
existing pianist.

Don't expect learning from a recording is up to it, but a high end
keyboard capturing all the input for training should be OK. Obviously
the person doing the training would need to be highly skilled. Too
perfect may be a fail as well since it could end up sounding like a
machine. May need a selection of styles by different composers.

Audio output is pretty good already, with physics simulators etc. Too
much to compare a live performance in a concert hall, but playing in the
car or on headphones should be indistinguishable.

Why piano and not guitar? Midi keyboards are good a capturing all the
input data, guitar is a lot more complicated with bending strings etc.

Not sure if a neural net solution is the best, but chip manufacturers
are coming out with super chips, and something like this seems a good
application.

For clarity: no intention for a mechanical player robot. Also solo
pieces and not with an orchestra or conductor.

The whole thing might exist already, not in that particular loop.
