Positive-going sawtooth waves raise the pitch of the oscillators and open the filter's CUTOFF.
Negative-going sawtooth waves lower the pitch of the oscillators and close the filter's CUTOFF.
VOICE MODULATION
The two sources of VOICE MODULATION are the filter's CONTOUR GENERATOR and
OSCILLATOR 3. Any function that changes or modulates these two sources will in turn be reflected
in the character of voice modulation sent to the various possible destinations.

CONTROL
The major distinction between LFO and VOICE MODULATION is that there is only one master
LFO, while there is an entirely different situation with VOICE MODULATION. Since there are six
filter CONTOUR GENERATORS (one for each of the six voices), every time you trigger one of the
six, you get control voltages that vary with time. These voltages can be applied to the frequency and/or
the pulse widths of the first two oscillators, and/or to the filter's CUTOFF frequency of that voice. To
hear this effect set up the following patch:
