wealth of programming capabilities for the sound designer.
The PCM 90 contains a built-in library of 250 reverb effects that simulate realistic

spaces. The presets are organized into 5 Banks of 50, and are functionally

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.
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 PCM 90 uses 5 stereo algorithms to create different types of reverb effects.
Each 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.
