theAttack,Sustain,andDecaycharacteristicsoftheEnvelopeGenerator
will be used as the modulation source.
LFO: LFO is short for Low Frequency Oscillator. The LFO produces a cyclic
change that can be used to create a repeating effect. When the switch is in
this position, the LFO will be used as the modulation source.
AMOUNT (AMOUNT KNOB)
Once a modulation source has been selected, the Amount knob can be used to
control the depth of the modulation effect.
DEST (DESTINATION SWITCH)
This switch allows you to choose which control will be affected by the chosen
ModulationSource.
PWM: When the switch is in this position, the Modulation source will be used
to continually vary the width of the Pulse wave. The VCO Wave switch must
be set to Pulse.
NOTE: Placing the switch in the PWM position will override the Pulse Width
Modulation (PWM) knob in the VCO section.
FREQ: When the switch is in this position, the Modulation source will be
used to continually vary the pitch of the Oscillator. This can be used to cre-
ate a gentle vibrato or wild swoops in pitch, all depending on the Amount

Modulation is a way of introducing subtle or drastic changes to a sound—or
anything in between. In order to use modulation effectively, you will need to
select a modulation source, choose a destination, and control the depth of
the effect.
