JR Samples Yamaha S90ES Natural Grand KONTAKT

Ok, I surrender, it's impressive that even though not one sample per note getting between 8 and 10 seconds through the 'loop decay' feature, something so small of just 79.7 MB can sound a perfect real piano.

unfortunately, some things come too late, imagine this piano 10 or 5 years ago, when came those gigantic piano banks that we neither use anymore.

In short, it is not just sampling, depends of the type of the piano, the acoustic room, the microphones and final treatment, as folding all together to achieve microtonal fine tune beatings as done by valves and their incredible harmonious parities, until the final compression.
