Local
Feedback
(Fader/Knob)
Checkbox
If
enabled,
no
feedback
is
sent
while
the
parameter
is
in
Touched
mode.
This
prevents
motorized
faders
from
“fighting”
against
the
user.
Key
Repeat
Checkbox
When
you
enable
the
Key
Repeat
checkbox,
the
assignment
is
repeatedly
executed.
The
Key
Repeat
Rate
slider—set
in
the
Mac
OS
X
Keyboard
&
Mouse
preferences—
determines
how
quickly
Logic
repeats
the
assignment.
The
duration
that
the
button/
controller
must
be
held
for,
before
the
assignment
is
repeated,
is
set
with
the
Delay
Until
Repeat
slider
in
the
Keyboard
&
Mouse
preferences.
Example:
This
facility
is
particularly
useful
for
the
zoom
function:
If
you
assign
a
key
repeat
command
to
the
Zoom
buttons
on
the
Logic
Control,
for
example,
you
can
simply
hold
down
the
Zoom
In
button.
Logic
will
zoom
in
until
the
Zoom
In
button
is
released.
This
mirrors
the
behavior
of
the
Zoom
key
commands.
In
earlier
versions,
you
had
to
repeatedly
press
the
(Logic
Control)
Zoom
buttons
to
zoom
in/out
more
than
one
level.
Note:
The
Key
Repeat
checkbox
is
only
available
for
key
commands,
key
presses
and
relative
value
changes.
If
any
other
assignment
class
is
selected,
the
checkbox
is
dimmed.
Logic
Pro
factory
key
command
assignments
already
support
the
Key
Repeat
function
(if
useful
and/or
applicable
to
the
control
surface/device)—making
changes
unnecessary
for
use
of
this
new
functionality.
If
you
want
to
enable
the
Key
Repeat
function
for
your
own
assignments,
you
may
need
to
use
the
re-learn
option
for
the
assigned
message.
Key
Repeat
messages
must
include
the
Lo7
byte,
which
provides
information
on
the
up
(released)
or
down
(pressed)
state
of
the
assigned
button.
Logic
guides
you
through
the
re-learning
process:
The
current
MIDI
message
is
automatically
cleared,
Learn
mode
is
activated,
and
a
Help
tag
prompts
you
to
send
the
desired
MIDI
message.
Releasing
the
assigned
button—after
learning
the
MIDI
message—automatically
creates
the
Lo7
byte,
and
assigns
the
Lo7
value
for
the
button
release
message
to
the
Min
parameter.
The
Lo7
value
for
the
„button
pressed“
message
is
automatically
assigned
to
the
Max
parameter.
Typically,
the
value
range
of
1–127
is
used
for
the
button
pressed
message.
The
zero
(0)
value
is
generally
used
for
button
released.
