Tweak (Dynamics)
Pressing the tweak button in LFO mode will open up the LFO dynamics
panel (shown above), giving you access to knobs to modulate the rate,
offset and width depending on the level of the incoming audio. There’s also
controls for the threshold, attack, and release settings of the envelope
detector that controls the dynamics modulation. You already have the LFO
modulating the pan position, but with the dynamics, you can modulate your
modulation in three different ways, simultaneously.
Threshold
Before we can really discuss the other controls located here, you first need
understand how the Threshold knob works as it affects the responsiveness
of the other knobs. The Threshold control allows you to define a specific
level (as in loudness) that the input must reach before any dynamic
processing of the Rate, Offset, or Width as set with the other knobs will be
implemented. The scale of the Threshold control is in standard ‘dB’.
There are two things to keep in mind; 1) as long as the level of the input
signal is above the Threshold level the modulation of Rate and Width will be
“on” and activated, and as soon as the level of the input signal falls below
the Threshold setting the modulation is turned “off” and de-activated, and
2) how “far” the input signal goes above the Threshold setting determines
how “deep” the modulation will go (with the maximum available mod Width
being defined by the settings of the other knobs.)
So the Threshold really determines how loud the signal must get before any
alteration of the Rate and Width will start and once the signal passes the
