That depends upon the quality of the digital piano. Cheap keyboards have
relatively short samples, and the periodic nature is very clearly heard
during the decay of a sustained note. This is not anywhere near as
noticeable in better units.

All I know is what they print in the literature that comes with them, and
they show multiple, selectable tuning schemes on the better models,
including equal temperament, just temperament, and several variations on
them with names I don't recall.

If you have to mic a saxophone, the rest of the band is too loud.
