Why can’t a digital piano perfectly emulate an acoustic piano?

649 viewsEngineeringOther

It seems like it should be pretty simple to just record the sound of a concert grand and play it back on a speaker. In fact, that’s what we do for studio albums. Is it the sustain pedal that causes the main difference in sound between an acoustic and a digital? Or would playing both without the pedal still sound different? I actually own a pretty sophisticated digital piano, the Kawai CA49, and it sounds a lot better than cheaper pianos, but I probably wouldn’t be able to tell the difference between it and an upright acoustic.

I mean they do make pretty flipping good electric pianos, and even guitar amps (see line 6) but the fundamental way you’re making the sound is different – basically an oscillating string vs a loud speaker (paper cone and a magnet).
