It hasn't changed my view on pitch controls though - 28ppm is very,
very tiny. I doubt if even those with "perfect pitch" could reliably
detect a frequency error of 100ppm (0.1Hz at 1kHz), never mind 28ppm
without something else to compare it with - not a likely circumstance
when one is attempting to listen to the music! The pitch control is
only useful to those attempting to compare players. :-)

1 cent of pitch ( one hudredth of a semitone) is a little over 500 ppm.

28ppm or 100 ppm will most certainly be inaudible.

Maybe the 'pitch control' is to use as an adjustment for out-of-tune
singing or perfoming... :-)

Slainte,
