Mode
Defines
the
way
the
incoming
value
modifies
the
current
parameter
value.
You
can
choose
between
the
following
parameters:
Â
Direct—The
incoming
value
is
the
new
parameter
value.
 Toggle—If
the
parameter’s
current
value
is
0,
it
is
set
to
the
incoming
value.
Otherwise
it
is
set
to
0.
This
option
is
useful
for
buttons
which
toggle
a
value:
Mute,
Solo,
and
so
on.
 Scale—The
incoming
value
is
scaled
from
its
value
range
to
the
destination
parameter’s
value
range.
Most
useful
for
faders
and
rotary
pots.
 Relative—The
incoming
value
is
added
to
the
parameter’s
current
value.
Used
by
encoders,
but
also
for
buttons
that
increment/decrement
by
a
certain
amount
(set
by
the
Multiply
parameter).
 Rotate—The
incoming
value
is
added
to
the
parameter’s
current
value,
cycling
between
maximum
and
minimum
values.
This
is
useful
for
button
presses
that
cycle
between
modes:
automation
mode,
for
example.
 X-OR—The
value
defines
a
bit
mask
which
is
applied
to
the
parameter’s
current
value
with
the
“exclusive
or”
Boolean
operation.
Useful
for
enabling/disabling
single
Object
types
in
Global
View.
Feedback
Defines
the
way
the
parameter’s
current
value
is
displayed
on
the
control
surface.
You
can
choose
between
the
following
options:
Â
None—No
feedback
is
sent.
 Single
Dot/Line—LED
rings:
only
one
LED;
LCDs:
a
single
vertical
line.
 Left
to
Right
Bar—A
bar
from
the
minimum
to
the
current
value.
 Right
to
Left
Bar—A
bar
from
the
current
value
to
the
maximum.
 Q/Spread—A
bar
from
the
center
to
the
current
value.
 Ascending
Bar
LCDs—A
bar
from
the
bottom
to
the
current
value.
 Descending
Bar
LCDs—A
bar
from
the
top
to
the
current
value.
 Text
Only—LED
rings:
no
feedback;
LCDs:
no
feedback
as
a
graphic
element.
 Automatic—Dependent
on
the
currently
assigned
parameter,
the
most
suitable
feedback
mode
is
used:
Plug-in
and
Instrument
parameters
carry
this
information,
Pan
uses
Single
Dot/Line,
all
other
parameters
use
Left
to
Right
Bar.
Note:
Feedback
only
works
for
supported
control
surfaces,
and
not
all
settings
are
available
for
all
controls.
Text
Feedback
Checkbox
If
enabled,
a
textual
representation
of
the
current
value
is
sent
to
the
control
surface’s
display.
The
plug-in
determines
the
display
position
and
number
of
characters
that
are
used.
