Stretching and electric pianos

[Jason Kanter]

The sampling differs across makes and models, but except for perhaps the
high-end Kurzweil it is not every note. The general rule is they sample
about one note every octave and then mathematically extrapolate the one note
to the next five semitones up and down. Play an electronic keyboard
chromatically and you can often hear the jumps when the sample switches.

When they sample a piano they are sampling the sound and the tuning.   I
don't know if they sample for every note?...but it seems to me the tuning
would match a piano...why not just play one with a real piano and see if is
close enough...?   It will be.   If anything playing together will give a
fatter sound if not perfectly in tune.

Hello all, just a quetion about electric pianos...
 
Does any of you have an idea if electric pianos are stretched to allow to
have them tuned with a real piano, or not ?
