Function
Button
Zone
There
are
three
areas
in
this
zone—Modifiers,
Automation,
and
Utilities.
Modifier
Buttons
The
four
buttons
in
this
area
are
similar
to
those
found
on
your
computer
keyboard
(but
are
independent
from
the
keyboard
modifiers).
Many
Logic
functions
behave
differently
when
one
or
more
“modifier”
key(s)
is
pressed,
in
conjunction
with
another
key
or
mouse
click.
This
also
applies
to
the
Logic
Control.
All
“modified”
Logic
Control
commands
are
covered
in
each
function’s
description.
A
generic
description
of
each
button
follows:
Â
SHIFT—an
alternate
function/meaning
for
a
button.
 OPTION—the
function
applies
to
all
objects.
For
relative
value
changes:
the
value
is
set
to
the
minimum,
default,
or
maximum
value,
depending
on
whether
you
increase/decrease
it.
 CONTROL—while
held
down,
the
Group
Clutch
is
engaged—Track
Groups
are
temporarily
disabled.
 x /ALT—fine
tuning/variation
of
the
function.
Automation
Buttons
The
five
buttons
in
this
area

the
various
automation
modes
of
Logic.
These
work
in
conjunction
with
the
channel
SELECT
buttons.
Simply
choose
the
channel
you
wish
to
automate,
select
the

mode
via

The
