Chapter 3: Mackie HUI Control Surface 59
for finer control of setting values. In velocity-sen-
sitive mode, the speed at which you sweep
through encoded values depends on how
quickly you turn the knob.
The rotary encoders on the HUI channel strips
(which are used for adjusting send levels and
pan controls) operate in fixed mode only.
The rotary encoders in the DSP Edit/Assign sec-
tion can behave in a fixed or velocity-sensitive
manner (the default setting is velocity sensitive).
To toggle the rotary encoder mode, press the F5
switch.
Automation Mode Indicator
If a plug-in parameter is enabled for automation
(Touch, Latch, or Write), the 6 o’clock position
LED (located in the bottom center of the V-POT
LED collar) flashes. If automation data for the
plug-in control is being recorded, the 6 o’clock
LED lights.
Touch Time-Out for V-POT Editing
Since V-POTs are not touch-sensitive, when you
stop moving them, Pro Tools continues to write
automation for the Touch Timeout period. After
the Touch Timeout period, writing of automa-
tion stops and the automation data returns to its
previous automation value.
In addition, you can stop the writing of automa-
tion by stopping the Pro Tools transport.
You may want to use Latch mode to record plug-
in parameter automation changes using a
V-POT. With Latch Automation, you can begin
writing automation (by moving a V-POT) at any
point during an automation pass, and the
V-POT will not time out in the middle of the
pass because you are not moving it.
Assigning Plug-Ins and
Hardware I/O Inserts
ASSIGN Switch
You can assign plug-ins or Hardware I/O inserts
from HUI.
NOTE: Assignments cannot be made when
Pro Tools is playing back or recording. If you are in
Assign mode and start playback or recording in
Pro Tools, the ASSIGN process is cancelled.
To assign a Plug-In or Hardware I/O on a single
channel:
1 Press the INSERT switch on the channel. The
INSERT switch LED lights, the associated track
name is outlined in red in the Mix window.
2 Press the ASSIGN switch in the DSP Edit/As-
sign section (not in the Select/Assign section).
The ASSIGN switch LED flashes.
If you are in Assign mode and you press the IN-
SERT switch on another channel strip, the As-
sign process is cancelled.
3 Under the insert that you want to assign, ro-
tate the V-POT encoder to choose a plug-in or
Hardware I/O pairs.
When you rotate the V-POT encoder, its accom-
panying SELECT switch flashes, indicating the
insert is being assigned or edited. (The switch
will not flash if the assignment is unchanged.)
Refer to the Pro Tools Reference Guide for
details on automating plug-ins.
