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.

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_AP260_460_MIDI_E_EN.pdf > In terms of velocity vs. amplitude I would guess that 127 levels at 1db > per level covers more than most ADC's would show.
