Editing An Effect - Lexicon PCM 91 - REV 1 User Manual

Basic Operation
ROW 1 TAP
(continued)
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 5 algorithms and 250 preset effects, the PCM 91 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
into a simple edit matrix. In addition to providing this powerful
sound design capability, the PCM 91 also allows 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 91 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.
2-22
When shipped, the PCM 91 will power up with the first preset
(P0 0.0 Deep Blue) loaded. The following display will appear:
Bank
Program Bank ID
Matrix Location
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 the
Custom row of the edit matrix, 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, and some have text
assigned to range values for even greater clarity. In some of the
presets, the changes effected by ADJUST will be as simple as
altering the wet/dry mix. In others, turning ADJUST will affect
multiple parameters over the complete control range of 0-127.
Details on how to create your own ADJUST knob patches are given
at the end of this chapter under Patching.
Controlling the Soft Knob with a Foot Pedal
If you have a foot pedal connected to the PCM 91 rear panel Foot
Controller jack, you can use it to control the soft knob patch. (Note
that no MIDI connections are required to do this.) To assign a foot
pedal control over the soft knob patches, set both Control mode
3.5 ADJUST and Control mode 3.5 Foot Pedal to the same MIDI
Controller. See Chapter 5 MIDI Operation.
