Understanding Effect Algorithms and Program Structures
Effect algorithms
This unit contains three types of effect algorithms: 4ch, 2ch,
and Mono-Pair.
Mono-Pair
The 4ch effects (algorithms # 01~09) are designed to handle
four channels simultaneously. These are also the highest
quality effects. Consequently, programs containing these
effects can not contain any other effects.
2ch effects (algorithms # 10~36) and Mono-Pair effects
(algorithms # 37~45), on the other hand, are designed to
handle two channels simultaneously and can be used in
various combinations within a program. Each program can
contain two 2ch effects, two Mono-pair effects, or one 2ch
effect and one Mono-Pair effect.
The 2ch effects are "traditional" stereo effects.
Mono-Pair effects are combinations of two parallel mono
effects (one for each channel).

Program structures
Each program can contain up two effects (FxA and FxB)
depending on the type of effect selected.
If a 2ch or Mono-Pair effects are selected, the program
contains two effects (one, or both can be turned off if
necessary). When a program contains two effects, the way
the unit routes the signals through the effects is controlled
by the program structure. There are two possible program
structures: parallel (/) and serial (m).

The sound from FxA is fed into FxB for further
processing before being output.
If a 4ch effect is selected, the program contains only one
effect (the other effect is automatically disabled).
