The Effects and Parameters
Originally, flanging effects were
created by simultaneously playing
two identical programs on two tape
recorders, then using hand pres-
sure against the flange of the tape
reels to slow down first one ma-
chine, then the other. The result
was a series of changing phase
cancellations and reinforcements,
providing a comb filter and a char-
acteristic swishing, tunneling and
fading sound.
In the MPX 1, the Flanger ef-
fects are two-tap delays. The first
tap is fixed, and the second sweeps
past it. Mixing the two taps to-
gether creates a flanging effect. In
Flanger (M), the moving tap is
swept with an internal LFO.
In the stereo version, Flanger
(S), the delays are modulated by
two sine waves from the same
LFO. The phase relation between
the two waves is set by the Phase
parameter.
