Pressing this button allows
you to edit the
Randomness
parameter. Pressing the
Randomness button a second
time allows you to select
between Linear and Gaussian random
distribution shapes, as described above.
Pressing the encoder again, or pressing the
Randomness button from here exits back to
Program Mode.
This Randomness setting interacts with the
Level Mode setting as follows:
>
If Level Mode is set to Abs or AbsQ,
the Randomness Amount defines the
symmetrical range above and below the
Target Level setting within which the final
Target Level will be randomly set.
An example: If the Target Level is set to
0.75V and the Randomness Amount is set
to 1.25V, the actual Target values will fall
somewhere between 2.00V and -0.50V.
>
If Level Mode is set to Rel or RelQ,
the Randomness Amount defines a
symmetrical range above and below the
Relative Target Level setting within which
the Target Level will be randomly set.
The resulting value is summed with the
previous segment’s final value to obtain
the actual
Target Level value.
Another example: If the Relative Target
Level is set to -1.2V and the Randomness
Amount is set to 0.25V, the actual Target
value will fall somewhere between 0.95V
and 1.45V
below the previous segment’s
final value.
Some Randomness Examples
Sample and Hold in One Segment
With the Randomness parameter, we can
program a flexible sample and hold using
only one segment. Here’s how:
1. Use the Load Preset function to load
any preset. Immediately use the Save
Preset function to save the preset to an
empty location. Name it “ 1 SEG S&H ” (or
whatever else you prefer).
2. Enter Program Mode and program
Segment 1 as follows:
Time: 1.000 sec.
Level: 0.000V Absolute
Randomness: +/-3.00V Linear
Transition Shape: 29 DC Delay
Jump Mode: Always at End
Jump Target: Segment 1
Assign Trigger 1 : Begin Segment 1
3. Patch the Control Forge’s + Output to
the 1V/Oct input of an oscillator and the
Trigger 1 output to the Gate In of an
envelope.
4. Patch the output of your oscillator through
whatever processing you want and into a
VCA controlled by the envelope.
5. Switch to Play Mode and press Control
Forge’s Manual Gate button to start your
contour running and listen to the result.
6. Use the Encoder to control the rate of
your sample and hold.
So, here’s what’s happening: You’ve created
a loop that continually plays Segment 1 over
and over. Since it’s using the DC Delay shape,
the voltage output remains steady each time
through the segment. With randomness set
to +/-3V, each time through the segment,
the voltage will be somewhere between
-3V and +3V (i.e, a +/- 3V range around the
programmed
Target Level of 0.000V).
Here are some things you can do to modify
your sample and hold:
>
Change the Randomness amount. The
overall range of the sample and hold can
be anywhere from a few cents up to a full
10 octaves with
Randomness set to +/-
5.00V.
>
Change the Randomness mode to
Gaussian to maintain the full range of
the amount setting, but have more of the
values be closer to the Target Level of 0V.
>
Set a different Target Level to offset
the Randomness range. Instead of 0V,
a Target Level of 1.500V for example,
