randomly determined shapes. The WAVESHAPE slider changes the basic waveform in different ways,
depending on which waveform is chosen with the WAVEFORM buttons.
 If the sawtooth wave is selected, and the WAVESHAPE slider is set to the middle of its range, the output
of the LFO rises and falls evenly between its lowest and highest values, creating a symmetric triangular
wave. If you move the WAVESHAPE slider to the left from its center, the LFO output rises more quickly
and falls more slowly. If you move the WAVESHAPE slider to the right, the LFO rises more slowly and falls
more quickly.
 If the pulse wave is selected, and the WAVESHAPE slider is set to the middle of its range, the output of
the LFO jumps between its lowest and highest values, staying for an equal period of time at both values.
If you move the WAVESHAPE slider to the left, the output stays at its highest value for a shorter period of
time. If you move the WAVESHAPE slider to the right, the output stays at lowest value for a shorter
period of time. In engineering terms, the WAVESHAPE slider varies the duty cycle of the rectangular
wave.
 If the sine wave is selected, and the WAVESHAPE slider is set to the middle of its range, the output of the
LFO varies smoothly between its lowest and highest values. The difference between a sine wave and a
triangle wave is that the triangle wave abruptly changes direction when it reaches its highest and lowest
values; whereas the sine wave gradually slows down, stops, and speeds up again when it changes
directions. Moving the WAVESHAPE slider warps and skews the sine wave without creating any sharp
corners in its shape. Its effect is far easier to hear than to describe.
 If the random wave is selected, and the WAVESHAPE slider is moved all the way to the left, the output of
the LFO jumps to a random value, changing at a rate determined by the numeric control. As you move the
WAVESHAPE slider to the right, the output moves more slowly from one random value to the next.
The diagram on the next page illustrates the different modulation signals generated by different settings of
the WAVEFORM and WAVESHAPE controls.
