you
to
adjust
whether
parameter
values
will
be
appended
by
the
measurement
“unit,”

example.
You

Customizing Control Surfaces
Logic
allows
you
to
reprogram
existing
assignments
for
supported
control
surfaces
and
to
program
new
assignments
for
unsupported
control
surfaces.
This
facility
allows
you
to
extend
the
use
of
faders,
knobs,
and
switches,
either
directly
or
through
the
use
of
modifier
commands.
As
an
example,
The
buttons
F1
to
F8
of
the
Logic
Control
are
assigned
to
screensets
1
to
8
by
default.
When
reassigned
directly,
or
combined
with
the
Shift,
Option,
Control,
and
Command
modifiers
(used
in
any
combination),
you
can
freely
assign
any
command
to
these
function
keys
(F1
to
F8).
To assign a MIDI control to a parameter:
1
Click the destination parameter that you want to “teach” Logic.

Activate
Learn
by
pressing
Command-L

the
menu
item
text).

continue
to
hold
down
the
computer’s

key

assigned
to
the
key
command),
a
Help
Tag
will
indicate
what
needs
to
be
done
next
(move

for
example).
Â

the
Command
key
is
held
down,

intended
control
