The Value/Enter Knob
Located just to the right of the custom LCD display, the [VALUE/ENTER] knob is
used to select Programs and adjust parameter values that appear in the display.
However, it is not just a knob, it is also a button. Depending on what parameter you
are editing, the [VALUE/ENTER] knob will work in either one of two ways:
Immediate. The desired value is selected by turning the [VALUE/ENTER] knob,
and immediately takes effect. This is the case when adjusting most parameters.
Deferred. The desired value is selected by turning the [VALUE/ENTER] knob, but
the new value will only take effect after the [VALUE/ENTER] button has been
pressed. The newly selected value will flash in the display until it is selected in
this manner. If you change the parameter back to its original setting, the value in
the display will not flash. Also, if you go to another Page, or select another
Function (by pressing any button), the parameter will be left unchanged. If you went
back to look at the previous parameter, it will be set back to its original setting.
This mode is used for parameters that cause architectural changes such as changing
a BlockÕs function, effect type, and routing signals.
The [VALUE/ENTER] button can also be used to step through Pages in the currently
selected mode. Except when a value is flashing on and off in the display, the
[VALUE/ENTER] button ordinarily doubles for the [PAGE >] button. If you change
the value of a parameter that uses Òdeferred mode,Ó, you must press the
[VALUE/ENTER] button to enter the new value (the display will stop flashing),
and then you can press it again to move to the next Page (or to the next parameter, if
more than one parameter appears in the display). This is a feature for power users
who want to be able to move around the various pages quickly and make changes as
fast as possible.
Unique Exception: When editing the Delay Time parameter of a Delay Block set to
either Tap Tempo Mono Delay or Tap Tempo Ping Pong, the [VALUE/ENTER]
button is used to ÒtapÓ in a tempo . See Chapter 6 for more information.
Adjusting the Display Contrast
Occasionally, the characters in the LCD display may be difficult to read,
depending on the viewing angle and existing lighting conditions. In such a situation,
adjust the contrast of the LCD display using the following procedure.
➀ Press [GLOBAL].
The display will go to the Global Mode Page 1.
ADJUST DISPLAY CONTRAST: 5
➁ Adjust the contrast by turning the [VALUE/ENTER] knob.
The displayÕs contrast and its value in the display will change.
