The
Control
Surface
preferences
window
is
accessible
via
the
Logic
>
Preferences

Control

>
Preferences
menu.
Note:
You
can
also
use
the
global
Control

Preferences
key
command.
General
The
following
section
outlines
the
General
control
surface
preferences.
Resolution
of
Relative
Controls
This
defines
the
default
resolution
of
controls
that
change
values
in
a
relative
manner.
The
default
is
128
steps.
As
an
example:
adjusting
the
Sample
Delay
(value
range
0
to
4000
ms)
in/decreases
the
value
by
40
ms
with
every
encoder
rotation
“tick,”
if
resolution
is
set
to
100.
Maximum
MIDI
Band
Width
This
slider
determines
the
maximum
amount
of
MIDI
bandwidth
that
can
be
used
by
your
control
surface.
By
default,
this
is
set
to
50%,
which
should
be
suitable
for
most
situations.
You
can
adjust
the
value
if
you
find
that
your
MIDI
or
automation
playback
is
being
affected.
Touching
fader
selects
track
Activation
of
this
parameter
will
automatically
select
the
track
that
corresponds
to
the
selected
fader.
You
require
a
device
that
features
touch-sensitive
faders
for
this
functionality
to
work.
Jog
resolution
depends
on
horizontal
zoom
If
your
control
surface
features
a
jog/shuttle
wheel
(or
similar),
the
precision
of
any
scrubbing
is
affected
by
the
horizontal
zoom
level
of
Logic.
To
retain
a
consistent
resolution,
regardless
of
Logic
window
zoom
levels,
disable
this
checkbox.
Pickup
Mode
If
your
control
surface
does
not
feature
motorized
faders
and
knobs,
parameter
changes—caused
by
playing
back
existing
automation—are
not
reflected
on
its
surface.
Such
control
surfaces
usually
offer
a
Pickup
mode.
In
Pickup
mode,
the
current
value
must
be
reached
(“picked
up”)
by
the
control
surface
before
a
value
change
can
occur.
This
prevents
sudden
“jumps”
of
parameter
values
after
parameter
changes
caused
by
playing
back
automation.
A
display
(usually
a
pair
of
LED’s)
will
indicate
the
direction/
distance
you
need
to
move
the
controller
to
match
(also
known
as
“NULL”)
the
settings
shown
in
Logic.
Once
you
have
matched
the
onscreen
values,
deactivate
Pickup
mode,
and
start
automating.
