Noodle Notation recorder

I'm not sure if this idea is necessary, but a jazz musician, or even someone who amid laughter sits down at the piano and starts to play would appreciate more than just a sonic recording of an impromptu session at the ivories or trashcan lids or bannister. (If this has been done I'd be obligated to see where's it baked at.) So a notation recorder would not only record the music, but also spit out the notes as notation to the trusty Mac or PC for further squidging. Mayb e I'm simply thinking of a standard digital tape recorder... The device would somehow combine a sample with notation software... It would sort-of replace the fancy Yamaha player piano that gives you mechanical playback & notation of your noodles.
