Description: A stereo flanger driven by a flexible stereo LFO. The LFO features a variety of selectable

waveshapes (described at the beginning of this chapter), modulation rate from the sub-audio through

the audio range, left-to-right phase offset, and a randomization function.

Notes: When LFO Shape is Samp/Hold, the LFO S/H Ratio param appears in the list. The two fields of

this param control the long-term variation and repetition period, respectively, of the sample-and-hold

waveform. When LFO Shape is Pulse, the LFO Pulse Width param appears in the list. This param

controls the duty cycle of the pulse waveform. The LFO L/R Phase sets the phase offset between the

left LFO and the right LFO (increasing this param can produce a stereo signal from a mono source).

LFO Rand Amount controls the amount of waveform randomization. When the param is set to 100%,

the waveshape is purely random, regardless of the setting of LFO Shape. LFO Rand Rate controls the

rate of the randomizer (the effect of this param can be heard only when LFO Rand Amount is

nonzero). The Flanger also features low and high shelving EQ, modulatable delays, and filtered

regeneration and cross-regeneration. The algo can be tapped after the flanger or after the regen delay

(the latter setting allows the wet signal to be delayed with respect to the dry).

I/O Characteristics: Stereo-in, stereo-out.
