Without doubts it should be 440 Hz +- 50 Cent.
+- 50 Cents is what the meter of the BOSS TU-12H chromatic tuner
displays and what you'll find for other software synth, such as e.g.
iSymphonic. The BOSS meter's Hz labelling is from 430 Hz to 450 Hz and
the Hz labelling of iSymphonic from 428 Hz to 452 Hz. IOW the
Cent labelling range from - 50 Cent to + 50 Cent is a little bit more
than the HZ labelling range from 428 Hz or 430 Hz to 450 Hz or 452 Hz.
