Control
Surface
Setup
This
parameter
defines
how
many
encoders
belong
to
Split
Upper,
leaving
the
remaining
encoders
to
Split
Lower.
A
value
of
0
means
that
Split
Mode
is
off—with
all
encoders
assigned
to
the
Split
Upper
area.
Instrument
Parameter
Page
The
Instrument
Parameter
Page
option
determines
the
parameter
(counted
from
1)
which
is
assigned
to
the
left-most
encoder
when
editing
an
Audio
Instrument.
The
next
Instrument
parameter
is
assigned
to
encoder
2,
and
so
on.
This
applies
to
Split
Upper
when
Split
Mode
is
enabled.
Inst
Parameter
Page
(Split
Lower)
As
above,
but
for
Split
Lower.
Insert
Slot
Determines
the
current
Insert
slot
number
for
both
selecting
a
plug-in
(in
Plug-in
Channel
Strip
View)
and
editing
its
parameters.
A
value
of
1
accesses
the
first
(top)
plug-
in
slot
on
each
channel.
A
value
of
2
accesses
the
second
plug-in
slot,
and
so
on.
With
Split
Mode
enabled,
this
applies
to
Split
Upper.
Insert
Slot
(Split
Lower)
As
with
Insert
Slot,
but
for
Split
Lower.
Plug-In
Parameter
Page
As
with
Instrument
Parameter
Page,
but
for
editing
plug-ins.
Having
these
parameters
separate
allows
you
to
quickly
switch
between
editing
an
instrument
and
an
effect
on
a
track,
without
the
need
to
adjust
the
parameter
page
every
time.
With
Split
Mode
enabled,
this
applies
to
Split
Upper.
Plug-In
Parameter
Page
(Split
Lower)
As
with
Plug-In
Parameter
Page,
but
for
Split
Lower.
Track
Specifies
the
currently
displayed
track
for
Channel
Strip
Views.
With
Split
Mode
enabled,
this
applies
to
Split
Upper.
Track
(Split
Lower)
As
with
Track,
but
for
Split
Lower.
Track
Lock
When
this
parameter
is
set
to
“on,”
selecting
a
track
in
Logic
does
not
change
the
Track
and
Track
(Split
Lower)
parameters.
In
other
words,
the
control
surface
group
continues
to
display
the
same
track,
independent
from
the
currently
selected
track.
When
Track
Lock
is
disabled,
the
control
surface
group
automatically
switches
to
the
selected
track,
whenever
a
track
is
selected.
