This is what Rampa has posted a while back. I have tried it since it's free for now.
AnimationI do not see the way to export out the animation/character and the piano.
All renders should be done within the app (at least for now).
Player (at least the girl which I have tried) has kind of short fingers. She probably has to play 5.5" octave piano (which hard to come by in real life).
9's and 10's are getting played, but her fingers do not reach the keys :).
But overall it's pretty much impressive for the AI.
SoundIt sounds with too much ambience and sustain, like player does not remove a foot from a damper pedal.
It's not critical if you would replace audio track with real life playing, but for import from MIDI file generated audio track would be retained.
And I did not find any settings to control the sound.
So here I have uploaded an mp3 file (Georgia on my Mind - original interpretation by 7notemode) into Concert Creator.
It took a while to AI process it, but the result was pretty much OK. There are little hiccups here and there, arpeggios are messed up a bit and there is a desynchronization with the original payer.
I then rendered, removed generated audio track (I did not like it) and replaced it with the original mp3 played by 7notemode.
As I said, there are some asynchronicity, but again it's still pretty much good for fairly complex tune animation (specially that it does not come from MIDI but just from an audio file).
Now, if it only could be exported (I guess you'd have to pay for it).
