PITCH MOD AMT (Pitch Modulation Amount)
This knob determines the amount of modulation being applied to the PITCH 
parameter. The shape of this modulation is determined by the position of the  
VCO MOD MIX knob. Rotate the PITCH MOD AMT knob clockwise to increase 
the amount of modulation being applied to the PITCH parameter. Rotate the  
PITCH MOD AMT knob counterclockwise to reduce the amount of modulation 
being applied to the PITCH parameter.
PWM AMT (Pulse Width Modulation Amount)
This knob determines the amount of modulation being applied to the  
PULSE WIDTH parameter. The shape of this modulation is determined by the 
position of the VCO MOD MIX knob. Rotate the PWM AMT knob clockwise 
to increase the amount of modulation being applied to the PULSE WIDTH 
parameter. Rotate the PWM AMT knob counterclockwise to reduce the 
amount of modulation being applied to the PULSE WIDTH parameter.
TIP: Pulse Width Modulation is a tried-and-true technique for creating motion 
and adding texture to a sound and is often used as the foundation for many  
string and pad types of sounds.
