PROGRAM SORTING
A program sorting function allows you to tag programs with
KeyWords and display only programs which have been tagged.
(Press Program Banks or Register Banks repeatedly to step through
all available banks and then to the KeyWord display.) The default
KeyWord selection, A to Z, allows you to view all of the presets in
alphabetical order. Others allow you to view, for example, only
Acoustic or Spatial effects. Each preset has already been assigned
from 1 to 4 KeyWords — you can easily change these assignments
in Edit mode. The selection of the KeyWord you want to use for
sorting is accessed in Control mode.
SOFT CONTROL
Each preset has one or more of its parameters patched to the front
panel ADJUST knob, giving you instant control over the primary
aspect of the effect — without going into Edit mode.
As many as four additional Custom Controls can be created for any
effect, allowing you to tailor presets for specific applications. We've
created some interesting Custom Controls in the presets, and
assigned them descriptive names. You can change both the
parameter assignments and the names in Edit mode.
THE ALGORITHMS
The PCM 91 uses 5 stereo algorithms to create different types of
reverb effects and 10 Dual Reverb algorithms which offer superb
dual reverb and cascade configured stereo effects. Each single
algorithm includes an uncompromised stereo reverb effect with
selected "tools" for ambience, post-processing, compression/
expansion, as well as modulation and patching parameters which
are common to each algorithm. Each dual algorithm contains two
independent reverb blocks, as well as the full set of modulation and
patch features in the single effects.
