Lexicon 480L Owner's Manual
How to Edit Parameters
The sounds of the programs supplied with the 480L
cover an astounding range of possibilities, but sooner
or later you will want to alter the sounds of the programs
to more perfectly fit your requirements. Each program
in the 480L contains a set of parameters that can be
edited to create a sound uniquely your own.
Just Move the LARC's Sliders
After loading a program, you can edit its parameters by
moving the LARC's sliders. Most parameters can be
edited in real time to alter an effect. However, a few
parameters (like SIZE) have such a radical effect on
the 480L's algorithms that the effects signal is muted
briefly when they are edited.
To indicate the parameter that a slider controls, an
abbreviated code appears in the display window above
each active slider. You can display a more descriptive
title and the current value for each parameter by
pressing the keys directly below each slider. Moving a
slider also displays this information.
In many cases, pressing a display key twice will en-
gage a vernier (fine) adjustment mode that allows very
precise adjustment. The display blinks to indicate that
the vernier mode is active.
Change Pages to Access More
Parameters
Because the programs in the 480L have more than the
six parameters which the LARC can display at one
time, parameters are grouped in several pages. Each
page contains up to six parameters. You can use either
of two methods to move between pages:
1. Press PAGE repeatedly to step through the pages
sequentially.
2. Press PAGE and then a numeric-select key to go
directly to the page you want.
IMPORTANT
When a new program is loaded or another page
is selected, each slider is deactivated (i.e., the
display does not change) until the slider is
moved through its preset value.
When changes have been made on a page, and you
move to a new page, the previous edits remain intact.
However, when a new program is loaded, the edits you
made disappear forever (unless you stored the edits in
a register).
How to Use Registers
The ability to edit parameters would be of little value if
there were no way for the 480L to store the edits. Not
to worry--the 480L has 100 registers available to store
edited versions of the programs. Registers are orga-
nized into banks, selected, and loaded exactly like the
programs. You can also edit parameters in a register,
and store the results in the same register or another
register.
There are five banks of ten registers in internal mem-
ory. Another five banks of ten registers can be stored
in a nonvolatile memory cartridge. One cartridge is
supplied with the unit, and additional cartridges may be
purchased.
IMPORTANT
Cartridges are equipped with a write protect
switch. When the switch is ON, it prevents the
480L from writing to the cartridge, regardless
of the register protection selected in the 480L.
Cartridges may be shipped with the write pro-
tect switch in the ON position.
