Control
Surface
Setup
Here
is
an
example
with
two
Logic
Control,
three
Logic
Control
XT
units
and
a
HUI:
Computer
icon
connected
to
three
rows,
as
below:
The
top
row,
consisting
of
Logic
Control
XT
#1,
Logic
Control
XT
#2
and
Logic
Control
#1
form
a
single
Control
Surface
Group
with
24
channels.
XT
#1
controls
channels
1
to
8,
XT
#2
controls
channels
9
to
16,
and
Logic
Control
#1
handles
channels
17
to
24.
Logic
Control
#2
and
Logic
Control
XT
#3
form
a
second
Control
Surface
Group,
displaying,
say
instruments
(on
channels
1
to
8)
and
busses
(on
channels
9
to
16).
The
HUI
forms
a
single
unit
control
surface
group.
Each
Control
Surface
Group
has
individual
settings,
such
as
Flip
Mode,
Fader
Bank
Offset,
Plug-in
Parameter
Bank
Offset
and
others.
This
allows
you
to
access,
edit,
and
automate
different
sections
of
the
Logic
mixer.
In
our
example,
the
three
units
in
the
top
row
could
be
used
for
control
over
audio
tracks
and
MIDI
channels.
In
the
middle
row,
Logic
Control
#2
could
be
used
for
Audio
Instrument
channels
1
to
8,
and
XT
#3
could
be
used
for
busses.
The
HUI
might
edit
group
definitions.
The
physical
placement
of
units,
and
the
way
you
use
them,
is
entirely
up
to
you.
Note:
The
placement
of
your
control
surface
units
in
relation
to
each
other
should
be
the
same
onscreen
as
in
the
real-world.
Simply
drag
’n
drop
the
desired
icon
horizontally
in
your
Control
Surface
Group
to
do
so.
