Editing An Effect; Average; Display; The Soft Knob - Lexicon PCM 81 - REV 2 User Manual

PCM 81

1.2 Average

This control allows you to average the last 2-8 taps. Higher
numbers mean that the response to incoming taps will be more
gradual. (The tempo is updated on every tap, but with a value
which is the average of the last 2-8 taps.) Higher average values are
more useful if you're trying to lock into a pre-recorded track.

1.3 Display

This control allows you to disable the flashing of the Tempo LED.
Turn ADJUST to select Off. The Tempo LED will turn off.

EDITING AN EFFECT

With 17 algorithms and 300 preset effects, the PCM 81 gives you
a lot to play with right out of the box. An enormous range of
editing control is provided for each algorithm, with parameters
organized in an edit matrix of as many as 100 main controls. In
addition to providing this powerful sound design capability, the
PCM 81 is also designed to allow you to customize these controls
for your day-to-day editing needs, or to simply use a subset of
controls specially designed for each preset.
This section will describe three basic levels of editing, from the
simplest "plug and play" method, through the full edit matrix.

THE SOFT KNOB

Every preset in the PCM 81 has one or more of its available
parameters patched to the front panel ADJUST knob. This Soft
Knob provides the first level of editing control. Once you have
loaded a preset, simply turn ADJUST to alter the effect.
When shipped, the PCM 81 will power up with the first preset (P0
0.0 Prime Blue) loaded. The following display will appear:
Indicates that the ADJUST knob is patched to one or more parameters in the currently-
running effect. This indicator will stay on even if another effect is selected for display.

Turn ADJUST. The display will change to show the name assigned
to the ADJUST patch, and the current value of the patch. Continue
turning ADJUST to change the value of the patch along its entire
range. The range of ADJUST knob control can be limited in Control
Mode, making it possible, for example, to have a range of only
0...1, in order to have the ADJUST knob behave as an Off/On
control. Many of the presets have range limits to make them more
convenient to use. In some of the presets, the changes effected by
ADJUST will be as simple as altering the wet/dry mix. In others,
such as the example shown below, turning ADJUST will glide you
all the way from a chorusing effect to a reverb effect over the
complete control range of 0-127.
The name that has been assigned to the ADJUST knob patch is shown here.
