Cool. I do wonder where the sample sets are that actually have 127 samples
per note.
No, those people don't use samples - we are talking full-size grand pianos here.
Those Disklaviers record and play back performances on actual concert instruments.
Think of it as a digital version of a Welte-Mignon player piano (the company has it's
origins
here in Freiburg/Germany). The local museum does regular concerts with roles recorded by
famous soloist/composers from the first half of the last century.
IIRC the velocity resolution on those roles is higher than the 7 bits used by midi.
Certainly Pianoteq might have a full range but most of
the
electric pianos I have heard sound more like in "Bennie" than anything
that actually came from strings. I am talking about the people who walk
into a music store and buy an electric piano or other stage keyboard.
Now any of those people would prefer to sit down in front of an acoustic
piano, but none of them can afford (or are willing to afford) an electric
stage/home piano which actually sounds real. Remember that "most" people
would never think about using a keyboard controller to get sound from
their computer.
???
In the case of keyboard synth combinations, where the
signal path is
kb->midi->internal synth. MIDI 2 may show some improvements that even the
average person will notice. In time such an instrument may even be cheap
enough for "most" people. However, it seems to me that the synth in the
pianos I have seen does not even fully use the 128 velocity values
available now.
IIRC the Roli keyboards have better resolution and those are used quite often for
contemporary music performance.
Some Casio E-Pianos seem to have high-resolution velocity values (14 bit), see
https://support.casio.com/storage/en/manual/pdf/EN/008/PX760_860_1500_160_A…
In terms of velocity vs. amplitude I would guess that
127 levels at 1db
per level covers more than most ADC's would show. At .5db per level the
range is still probably wider than the dynamic range available in a nice
quiet studio/sound stage... so I would hope that the range of timbre
differences makes a wider range of velocities worth while. I would like to
see a blind AB test where the same performance is rendered by the same
synth in both MIDI 1 and MIDI 2.
Not what our piano teachers say ;-)
