nano VCV Random CV Generator Module
Specifications:
- Random CV generator
- 4 types of randomness
- Triggerable sample-and-hold function
- Internal clock tempo control
- Probability setting for random value generation
- Blend old with new values control
- Shape control for random outputs
Product Usage Instructions
Powering Up:
- Turn off the power of your modular synthesizer.
- Double check the power cord polarity to avoid damaging electronic circuits.
- Ensure the RED mark on the PCB power connector matches the colored line on the ribbon cable.
- Turn on your modular system after verifying all connections.
- If you notice any anomalies, turn off your system immediately and recheck connections.
Description:
VCV Random is a hardware version of a classic from the VCV Rack fundamental
library. It serves as a random CV generator with 4 types of randomness and a
triggerable sample-and-hold function. The sliders on the module allow you to
control the internal clock tempo, probability of triggering, blending old with
new values, and shaping the random outputs.
Layout:
The randomness sliders on the module include RATE (tempo control), PROB
(probability setting), RND (blending previous and random values), and SHAPE
(transition shape control). The module also features CV inputs, trigger input,
offset switch, and trigger output.
Controls:
The module’s controls include RATE for adjusting clock tempo, PROB for
setting probability of new random values, RND for blending values, and SHAPE
for controlling transition shape. The CV attenuverters allow you to adjust
signal strength and direction based on the switch position (unipolar or
bipolar).
FAQ:
-
Q: What should I do if I notice anomalies after powering up?
A: If you notice any anomalies after powering up, turn off your system immediately and recheck all connections to ensure correct setup and prevent potential damage. -
Q: How do I set the tempo of the internal clock?
A: Use the RATE slider to adjust the tempo of the internal clock. Each clock trigger will be indicated by a blinking light on the slider.
Thank you for choosing VCV RANDOM for your Eurorack System.
Powering up
Turn off the power of your modular synthesizer. Double check the power cord
polarity. If you plug the module backwards you might damage its electronic
circuits.
If you flip over your VCV RANDOM, you will find the “RED” mark at the PCB power connector, which must match the colored line on the ribbon cable. Once you have checked all the connections, you can turn on your modular system. If you notice any anomalies, turn your system off right away and check again your connections.
Description
VCV Random is the hardware version of a well-known classic from the VCV Rack fundamental library. A random CV generator with 4 types of randomness and a triggerable sample-and-hold function. Its sliders allow you to set the internal clock tempo (RATE), shape the probability of triggering (PROB), blend old with new values (RND) and set the shape of all four random outputs (SHAPE).
Layout
This image will clarify the function of each of the elements of the module.
Controls
Randomness Sliders
RATE
Adjusts the internal clock’s tempo. Upon each clock trigger, the RATE slider
light blinks, and there is a chance for the internal random source to generate
a new value.
PROB
Sets the probability of generating a new random value each clock cycle. If one
is generated, the PROB slider light blinks and a pulse is emitted from the
TRIG output.
RND
Blends the previous value with a random one, in a proportion determined by the
RND slider. It affects the range of the voltage output.
SHAPE
Controls the transition shape to the new random value across all four outputs.
CV Attenuverters
These knobs control how much and in what way an external signal affects the
randomness parameters.
In the center position (0), the signal does not affect the parameter. If you turn it to the right, it attenuates (turns down the strength) the signal. If you turn it to the left, it inverts the signal, making things that were going up, go down instead, and vice versa.
Offset Switch
Unipolar (0V to 10V).
With the switch facing up, the signal starts at 0 volts and can go up to 10
volts. This setting is great for controlling things that have a clear starting
and ending point, like the brightness of a light.
Bipolar (-5V to 5V).
With the switch facing down, the signal can move both ways: it starts in the
middle (at 0), can go down to -5 volts, or up to 5 volts. This is useful for
parameters that need to move in two directions, like pitch, which can go
higher or lower from a central note.
Inputs & Outputs
Inputs
/CV INPUTS
Modulate the Rate, Probability, Random Range, and Shape with an external
voltage. The applied signal is summed to each slider position.
/TRIG IN
If the TRIG input is patched, the RATE slider is ignored, and the clock is
only triggered when an external trigger is received. The PROB slider is used
to filter this trigger by some probability.
/IN
If the IN input is patched, this external voltage is used instead of a random
voltage upon each trigger. The RND slider has no effect.
Outputs
/TRIG OUT
if a new value is generated, a pulse is emitted from the TRIG output.
Outputs
/STEP
The STEP output jumps to the new value in one step at 0% SHAPE, and divides
the transition into 16 steps at 100% SHAPE.
/LIN
The LIN output immediately reaches the new value at 0% SHAPE, and takes the
whole clock cycle to do so at 100% SHAPE, staying constant in between.
/EXP
The EXP output shifts exponentially, becoming linear at 100% SHAPE, with its
pace adjusted by the SHAPE slider.
/SMTH
The SMTH output transitions smoothly, with the speed controlled by the SHAPE
setting, holding at the target until the cycle ends.
