Chapter 9 Modulation 109
Modulation Sources
The oscillator Frequency and Dry/Wet parameters can be modulated via the internal
envelope follower and LFO. The oscillator frequency even allows modulation through
the 0 Hz point, thus changing the oscillation direction.
Envelope Follower
The envelope follower analyzes the amplitude (volume) of the input signal and uses
this to create a continuously changing control signal—a dynamic volume envelope of
the input signal. This control signal can be used for modulation purposes.
 Power button: Turns the envelope follower on or off.
 Sens(itivity) slider and field: Determines how responsive the envelope follower is to
the input signal. At lower settings, the envelope follower will only react to the most
dominant signal peaks. At higher settings, the envelope follower will track the signal
more closely, but may react less dynamically.
 Attack slider and field: Sets the response time of the envelope follower.
 Decay slider and field: Controls the time it takes the envelope follower to return from
a higher to a lower value.
LFO
The LFO is the second modulation source. The LFO produces continuous, cycled control
signals.
 Power button: Turns the LFO on or off.
 Symmetry and Smooth sliders and fields: These controls shape the LFO waveform. The
LFO waveform display provides visual feedback.
 Rate knob and field: Sets the cycle speed of the LFO.
 Sync button: Turn this on to synchronize the LFO cycles (LFO rate) with the project
tempo, using musical note values.
