When Ray Kurzweil sampled the 1st acoustic instrument, what was his goal ? IMO opinion the answer has always been authenticity.
Wikipedia says this about Kurzweil " The company launched the K250 synthesizer/sampler in 1984: while limited by today's standards and quite expensive, it was considered to be the first really successful attempt to emulate the complex sound of a grand piano."
Emulate the sound of the acoustic piano was the objective.
Roland, Yamaha, Korg and all other manufacturers was after authenticity. Personally Ketron is the sound I wanted.
How well do you think the manufacturers have done with reproducing authentic sounds ?
