According to hyperphysics website, 440Hz is A*4*, not A3.
A bass tuning website confirms this.
So does "trentradio.ca".
I have seen no references to A3 being 440, other than the tone generator
program, which also seems to label triangle+sawtooth waves iffily. It
calls middle C "C3", when it appears that middle C is "C4" instead. Perhaps
that's the source of the error?

NB: This set of frequencies leaves the 27.5Hz signal as *A0*, not "A -1",
which means I don't have to do that horrible horrible fudge :)

B7 is 3951Hz though. Might increase range accordingly?

Furthermore, it sounds like "tremolo arms" (which pitch-shift on guitars)
are utterly misnamed: tremolo is *amplitude* modulation, and vibrato is
pitch modulation :(
ARGH! And it seems they do the opposite naming too. BASTARDS!
Ok, in that case, I'm going to just refer to these modulations as AM and FM.
I can't be doing with having ambiguous names.

Ok. On May 7th 2005, tested Patel against a tone generator program. Patel's
playing of note 0x0C (which should correspond to A1), seems to be as close to
the tone generator's 55Hz (which should be the correct frequency of A1) as
I can tell. If it's off at all, it's not enough to be visible. AFAICT the
only reason the two outputs sound different is Patel's use of only 1 of
4 channels makes it quieter than the tone generator.

Nonetheless, when playing A4 (0x30 in Patel, or 440Hz), there seems to be
a slight difference in pitch, but it's quite hard to tell.
