DSP Edit/Assign Display
The DSP Edit/Assign display is a two-line by 40-
character vacuum fluorescent display. This dis-
play shows information about individual chan-
nel inserts, plug-in parameters (for plug-in edit-
ing), and messages about Pro Tools or HUI
status.
When a channel is selected via its INSERT switch
in the fader section of HUI, the display shows
one of the following:
◆ The names of the current inserts (Insert Dis-
play mode).
◆ Plug-in parameter pages for editing a plug-in
on that channel (Parameter display mode).
The display also shows special modal dialog
messages. See “Troubleshooting and Diagnos-
tics” on page 66 for details.
Display Brightness
The HUI display brightness is adjustable in four
levels. To toggle the display between these four
brightness levels, hold OPT/ALL and then press
INSERT/PARAM.
When HUI goes offline, it reverts to the lowest
level to preserve its display.
DSP SELECT Switches and V-POT
Encoders
Under the HUI display, there are four sets of SE-
LECT switches and V-POT encoders. The SE-
LECT switch and V-POT encoder have different
functions depending on whether the display is
currently in Insert display mode or Parameter
display mode:
◆ In Insert mode, the SELECT switch is used to
select an insert for editing or assignment. The
V-POT encoder is used in Assign mode to choose
from a list of plug-ins or Hardware I/O pairs for
assignment.
◆ In Parameter mode, these controls are used for
plug-in editing. The four switches and four en-
coders represent the controls in a plug-in inter-
face. Controls are mapped to pages (or logical
groups) of controls. Generally, the switches con-
trol switched parameters (for example, EQ band
in/out controls). The encoders control continu-
ously variable parameters (such as gain), or pa-
rameters that contain several discrete choices
(such as choosing different reverb algorithms in
a reverb plug-in).
Rotary Knob Settings
Many of the rotary encoders on the HUI can op-
erate in fixed or velocity-sensitive modes. In fixed
mode, a single complete turn of the knob goes
through the entire range of values, independent
of how quickly you turn it. When moving rotary
encoders in fixed mode, you can hold ALT/FINE
