There isn't just 1 [osc~] object in the whole system, there are (at
least) 6, 3 for each of 2 triaxial accelerometers.
If I try an [osc~] into a [dac~] independently there is no problem
(driven "by hand").
I'll try again just driving the frequency of 1 [osc~] with 1 dimension
of 1 accelerometer (happens to be a Wiimote via OSC).

A good idea to improve that anyway, and I did, however there is no
obvious audio improvement.

Precisely why I am "bamboozled", it may well have another cause in my
wider synthesis system.
(I have used a quite similar accelerometer audio synthesis system for
years in JSyn without this trouble).
Thanks for taking the trouble to consider my situation and challenge my
I'll keep looking/listening, and try breaking things back down to a very
simple test suite first,
