Chapter 3: Mackie HUI Control Surface 61
The rotary encoders in the DSP Edit/Assign sec-
tion can behave in a velocity-sensitive or fixed
manner. To toggle the rotary encoder mode,
press the F5 switch.
DSP Parameter Value Display
When in parameters view, holding the OPTION
key while changing a DSP parameter value via
the encoder causes the value to be temporarily
displayed as a full 9 character value in the DSP
scribble display.
COMPARE Switch
Compare edited plug-in parameter settings to
the original settings with the COMPARE switch,
which mirrors the Compare button in a
Pro Tools plug-in.
BYPASS Switch
The BYPASS switch in the DSP Edit/Assign sec-
tion serves two functions:
◆ In Insert Display mode, as a bypass switch for
any plug-in insert
◆ In Parameter mode, as a Master Bypass for the
currently selected plug-in
The BYPASS switch in the DSP Edit/Assign sec-
tion functions differently from the Master BY-
PASS switch in the Select/Assign section. See
“Master BYPASS Switch” on page 49.
Bypass of Individual Inserts in Insert
Display Mode
If Insert Display mode is enabled, you can by-
pass a plug-in by holding down the BYPASS
switch (in the DSP Edit/Assign section), and
pressing the SELECT switch directly under the
plug-in insert in the display. When switching
bypass status for individual plug-ins in this
manner, the BYPASS switch LED will not light.
Bypass of Selected Plug-Ins in
Parameter Mode
If a plug-in is selected for editing and Parameter
mode is enabled, pressing the BYPASS switch (in
the DSP Edit/Assign section) engages the Master
Bypass control for the selected plug-in. In this
case, the BYPASS switch LED will light. When
switching plug-ins, the BYPASS switch LED will
indicate the bypass state of the currently se-
lected plug-in.
The COMPARE switch will function only in
plug-ins that are visible on-screen. Use the
ALT switch to open the currently active
plug-in.

BYPASS
You cannot bypass Hardware I/O inserts
from Pro Tools. To monitor playback with-
out a hardware insert, either set the Insert
Type Selector to “No Insert” or use a bypass
switch on the hardware device itself.
