Disklavier

After I edited there seemed to be less discrepancy, the performance seemed more crude. I had read the promo about the Pro technology which is summarized here: (lifted from Wikipedia)

In 1999, "Disklavier Pro" was introduced to the American market, the "II Pro". A key selling feature of this version was a claim of greater playback accuracy than had been possible with previously available models.[3] The Pro made use of a proprietary enhancement of MIDI data, which subdivided the timing information in an effort to allow greater precision. Rather than using the standard 127 levels of midi velocity, Yamaha introduced 1023 levels for KeyAfterTouch, NoteOn and NoteOff. A similar principle was applied to the pedal performance data, using 256 increments of measurement in an effort to allow finer capture and reproduction of, for example, half and quarter pedaling by the player. These developments allowed Yamaha to claim a greater overall accuracy in the reproduction of an original piano performance.[3]
I assumed that perhaps in editing in the Midi format I had lost something.
