Correction from above:
I was 'behind the times' with what Tunelab is able to do - it seems that with the new 3-part tuning, (available since last fall) it is much more responsive to the piano and calculates on a note by note basis and can end up with a non-smooth curve for a single partial.
Hi Ron. As we know, Tunelab users usually do NOT measure all the notes of
a piano, like users of Entropy or Dirk's Piano tuning software do. Tunelab
usually measures most of the C and F notes, and then extrapolates a
smooth curve from that.
So with the newer version of Tunelab, are they recommending to sample
ALL the notes of the piano, to get the most accurate tuning solution?
I was reading that the Minimum-Entropy algorithms, like Dirk's and Entropy,
create tuning solutions that could possibly be better than what a human
can do? If so, that would be a triumph of technology, although from a
practical point of view, it would make field tuning of different pianos, a
longer process. In other words, entropy software is better for pianos
you will tune more than once, because you can store the solution for
each piano, and not have to sample all the notes twice.
