Lexicon MPX 500 User Manual page 13

Basic Operation
The "Adjust" Knob
A special control in each program lets you make quick adjustments to the most critical parameters
of the sound. We have positioned this custom control under Edit knob 1 on Page 1 of each program
and refer to it as the Adjust knob in this manual.
In many cases, this parameter controls several effect parameters simultaneously to provide simple
control of a complex editing process. In many Chamber and Room programs, for example, this
parameters controls the "liveness" of the space by changing decay, EQ and early reflections all at the
same time. For easy identification, this parameter name will always appear in parentheses, as:
(Livenes). When you turn the knob, the bottom display line will temporarily show a more complete
description of its function in the running program.
NOTE: As the Adjust knob can access and control more internal controls than the 16 displayed
parameters in each program, there may be instances where this control (or Tap) will modify a
parameter which is not displayed on any of the program's edit pages. In these instances, the Edited
LED will light, even though no displayed parameters are highlighted.
Tap Tempo Functions
Varying the Rhythm
The MPX 500 Tempo features allow you to set the delay times and modulation rates of tempo-based
programs to the beat of the music. There are several ways to set tempo (40-400BPM), each of which
is described below. No matter which method you select, the current tempo rate will be displayed in
the upper right corner of the display, and the embedded LED in the Tap button will flash in tempo
whenever a program with tempo-controllable parameters is loaded . You can set a global tempo for
all of the MPX 500 programs, or have each program stored with its own tempo. (See System Mode. )
The global (g) or Program (p) system parameter selection is shown to the right of the tempo display.
