Dynamic
A Dynamic Flanger will trigger the LFO through one cycle of its sweep when the input signal crosses above
the programmed Threshold level. When the input signal crosses back, the LFO is reset and will trigger again
the next time the input signal crosses over the Threshold level. Threshold is set with the Special parameter.

Threshold
Delay:
Changes the predelay time in
±
1 millisecond steps. The total amount of predelay is 1 second (1000 ms.)
Size:
Changes the predelay time in
±
50 millisecond steps.
Regen: Sets the amount of positive or negative feedback, from
-99 to +100.
Negative numbers correspond to
inverted feedback.
Decay:
This parameter is used in Vocal class and sets the amount of time it
takes the effect to fade in and out after the Threshold level is crossed.
A graph of this control’s action is on page 66.
Shape:
Selects the LFO shape. Use the LFO Shapes table to match the
parameter’s value with an LFO waveform. Also, see page 65 for
Pitch:
Controls the LFO phase difference (in 30° increments) between the two outputs of
an engine group (Outputs #1 and #2, or Outputs #3 and #4). A setting of 0° creates
a normal flanger where both channels’ LFOs start at 0° (low). Any setting other than
0° will offset the second channel’s LFO by that many degrees. (See the LFO Offset
table.) Use this control to create uneven stereo flanger effects.
Note: In Discrete 4 (mono) routing, this parameter is not available.
Speed:
Sets the speed of the LFO between 0 and 10.5 cycles per second (Hz.)
Width:
Sets the LFO modulation width, or amount, from 0% to 100%.
Special: In Vocal and Gated classes, Special sets the audio input level (Threshold) that controls the gating action of
the effect. This parameter can be set in 1-dB increments, from 1 to 30 dB below full-scale. Normally, when
