UNIPOLAR PENDULUM: If the LIM menu's Polarity = Unipolar, and you
set a positive TRANSPOSE AMOUNT, accumulations will accrue in an
upward direction beginning at the stage pitch; rise to the Positive Limit,
then reverse direction and continue accumulating downward until the
stage's starting pitch is reached, then the accumulation reverses again.
No pitches below the stage pitch will occur.
The following examples Illustrate a unipolar pendulum with two different
TRANSPOSE AMOUNT values (+1 and +4).
If you set a negative TRANSPOSE AMOUNT, accumulations will accrue
in a downward direction beginning at the stage pitch; descend to the
Negative Limit, then reverse direction and ascend back to the stage
pitch, then reverse again. No pitches above the stage pitch will occur.
