Contrary to the documentation for the 6.0.7 Sound Manager, it does
*not* support frequencies specified as some number of Hertz, only
as discrete semitone note numbers.

I personally found this out with freqCmd, you've found it applies
to noteCmd as well.

My workaround was to use rateCmd to modify the pitch of the playing
note--this does support arbitrary fractional values, as documented.
It's a real kludge, I know, and I suspect it wouldn't work all that
well with a note that's already started playing. Myself, I was messing
around with notes of indefinite duration, so I could set the amplitude to
zero before changing the pitch, and then make it audible at the right
pitch.

The guy who wrote that Inside Mac chapter told me the reason for
the omission was to avoid compatibility problems with some software.
Hard to believe, but there you go...
