Logic Control
The SAVE LED illuminates as soon as any save-able change has been made in Logic.
Holding
down
the
OPTION
button
while
pressing
SAVE
opens
the
“Save
As”
file
selector
box.
Undo
Pressing
the
UNDO
button
undoes
the
last
undo-able
editing
step.
As
Logic
supports
near-unlimited
multiple
undo/redo,
the
green
UNDO
LED
does
not
illuminate
to
indicate
an
undo-able
step,
but
rather
to
indicate
that
Redo
is
available.
This
serves
as
a
warning
that
performing
a
reversible
editing
step
would
render
all
Redo
steps
unavailable.
Holding down the SHIFT button while pressing UNDO performs a “Redo.”
Holding
down
the
OPTION
button
while
pressing
UNDO
opens
the
Undo
History
window.
Cancel
If
an
alert
is
open
on-screen,
it
triggers
the
Cancel
(or
Abort)
button.
More
information
on
alerts
is
found
in
“
” on page 45. Pressing the CANCEL button
when
no
alert
is
opened
will
launch
the
Toolbox
at
the
current
on-screen
position
of
the
mouse
cursor.
Alternately,
it
will
perform
any
function
currently
assigned
to
the
computer
keyboard’s
Esc
key.
If
no
alert
is
open,
and
Logic
Control
is
currently
showing
the
contents
of
a
folder
track,
use
of
the
CANCEL
button
exits
the
folder.
CANCEL also enables you to invalidate a (blinking) parameter value pre-selection.
Enter
If an alert is open, the ENTER button triggers the default button. See “
” on page 45 for more information.
If
no
alert
is
open,
and
the
selected
track
is
a
folder
track,
the
ENTER
button
opens
the
folder.
