About the Dual Programs
The MPX 100 Dual programs combine
either a Delay or Reverb algorithm with a
Flange, a Pitch or a Chorus. Effects Lvl/Bal
controls the relative balance of each effect in
the combination.
Four routing configurations are used in
the variations of each Dual program: Dual
Stereo (Parallel), Cascade, Mono Split and
Dual Mono.
Variations 1-6 are set up in the Parallel
configuration - two stereo effects placed side
by side so that they receive and output stereo
audio from both left and right channels.

Variations 7-10 are set up in the Cas-
cade configuration - two stereo effects, one
placed after the other (for example, Flange-
Delay, Flange passes its stereo signal to the
Delay).
Variations 11-14 are set up in the Mono
Split configuration which is similar to Parallel,
however one effect (Flange) receives audio
from the left input and the other effect (Delay)
receives audio from the right input. Both
effects then output stereo audio.
Variations 15 and 16 are set up in the
Dual Mono configuration where one effect
(Flange) appears on the left channel only
and the other effect (Delay) appears on the
right channel only.
