Graphics and Curves
Several programs use an interface reminiscent of
an analog graphic equalizer. Two parameters are
used: an
x
value and a
y
value. The
x
value is the
horizontal position of the currently selected
graphical point, and the
y
value is the vertical position of the currently selected graphical
point. In our example to the right, the
x
value is
12500 Hz
, and the
y
value is
12.6 dB
.
With the cursor in the
y
field (as shown above), the
LEFT
and
RIGHT CURSOR
keys
change the
x
value, while the
KNOB
and
NUMERIC KEYPAD
change the
y
value. With the
cursor in the
x
field, the
LEFT
and
RIGHT CURSOR
keys, the
KNOB
, and the
NUMERIC
KEYPAD
all change the
x
value. Use the
UP
and
DOWN CURSOR
keys to move between
the graphic interface and other parameters on
the screen.
For example, pressing the
LEFT
CURSOR
key
several times on the above screen would change
the
x
value and result in the screen to the right.
Spinning the
KNOB
on the above screen would
change the
y
value and result in the screen to
the right.
Pressing the
DOWN CURSOR
key on the screen
above would move the cursor from the graphic
interface to the
Mast
parameter.
"Curve" modules behave just like "graphics," but their function is a little different.
Here we have loaded the program "
Band
Distort
" from the "
Inst - Distortion
"
bank. On the
curves
menu page in the
PARAMETER
area, we find two "curves." Think
of the audio signal being processed by this program as ranging in amplitude from -1 to 1.
The "curve" sets up an arbitrary relationship between the input amplitude and the output
amplitude. The
x
value is the input amplitude, and the
y
value is the corresponding output
amplitude. In the example above, an input amplitude of
-1.0
results in an output
amplitude of
-0.480
. By making the input amplitude slightly different from the output
amplitude, you can obtain a subtle distortion.
