Lexicon MPX 100 User Manual

Flange
In the MPX 100, the stereo Flanger has
two 2-tap delays —one per channel. The first
tap is fixed, and the second sweeps past it.
Mixing the two delay taps together creates
the flanging effect.
All of the variations of this program (9-16)
should be used with Mix set to fully Wet to
achieve the full flange effect.

Flanging effects were originally created by simultaneously recording and
playing back two identical programs on two tape recorders, then using hand
pressure against the flange of the tape reels to slow down first one machine, then
the other. The result was a series of changing phase cancellations and reinforce-
ments, with a characteristic swishing, tunnelling and fading sound.
