Sample And Hold Flashcards
What is a Sample and Hold?
A circuit or function in early synthesizers that enables the instantaneous value (voltage) of a waveform to be captured, and continues to output that value until the next sample is taken. This voltage is then used to control some other parameter in the synth such as a filter.
What happens when your sample and hold controls the v/oct of an oscillator?
It will output a random pitch every time it is activated.
What happens when you modulate via sample and hold the cutoff of a filter?
You will have a new randomly chosen value for the frequency of the cutoff.
What happens when we modulate via sample and hold the pan of our mixer in VCV Rack?
We can choose a random placement for the pan on every note
How would we create a bass line out of a moving line via Sample and Hold?
You can sample the v/ovt of the moving line at a slower tempo. Use this to create another voice an octave or two below the original melody.
Sample and hold is one of the primary ways that we add _______ in our patch.
Randomness (computer choice)
Sample and Hold samples this source of voltage to create a random value?
White Noise
Are sample and holds clockable (meaning can you control the sample and hold speed)?
Yes, most sample and holds accept an LFO Square input or clock source to run. The sample and hold in VCV by has a rate parameter that also controls this function.
The heart of any ______ patch is randomness - this can be applied via the sample and hold module.
Generative
A common use of sample and hold is to send it to an LFO. If you send a sample and hold to a sawtooth wave, the scope will output a _______.
Staircase shape
Slew Generators, in a synthesizer:
Smoothes the output of an incoming signal
Slew Generators are great for portamento. TRUE or FALSE
True. Slew Generators allow us to glide from one note to the next.
Slew Generators are also called:
Slew Limiters, Lag Processors
How can slew limitors be used with gates?
Gates are simple square waves. When ran through a slew limiter you can create envelope shapes with them.
