The Kyma Language for Sound Design, Version 4.5

SampleCloud
Sampling Category
Generates a cloud of short-duration grains, each using GrainEnv as an amplitude envelope on a short
segment of sound taken from the specified Sample at a point in the sample given by the TimeIndex. The
density of simultaneous grains within the cloud is controlled by Density, with the maximum number of
simultaneous grains given by MaxGrains. Amplitude controls an amplitude envelope over the *entire*
cloud (each individual grain amplitude is controlled by GrainEnv). Similarly, Duration is the duration of
the entire cloud, not of each individual grain. You can control the Frequency, stereo positioning, time
point within the sample, and the duration of each grain as well as specifying how much (if any) random
jitter should be added to each of these parameters (giving the cloud a more focused or a more dispersed
sound, depending on how much randomness is added to each of the parameters).
Sample
Enter the name of a mono sample file or click the disk icon to choose a file from the file dialog. This is the
source material for each of the short duration grains.
GrainEnv
This is the shape of the amplitude envelope on each grain. The wavetables in the Windows category
make the classic, smooth grain envelopes, and some of the shapes in Impulse Responses also give
interesting results.
MaxGrains
This is the maximum number of simultaneous grains. The smaller this number, the less computational
power the SampleCloud requires (but the less dense the texture you can generate). On a Capybara-66
you should be able to get around 28 simultaneous grains per cloud. For even denser textures, put more
than one SampleCloud into a Mixer, and give each cloud a different Seed value.
Amplitude
This is an overall level applied to the entire cloud. Paste an envelope generator into this field to give an
overall envelope to the cloud.
Density
Small Density values result in a sparse texture; large Density values generate a dense texture. This
controls the average number of new grains starting up at any given point in time.
GrainDur
This is the duration of each individual grain.
GrainDurJitter
Adds some amount of random jitter to the grain durations. When set to 1, the durations vary randomly
from 0 to twice the specified duration. When this is set to 0, all grains will have a duration of GrainDur. In
other words, the actual grain duration for each grain is:
GrainDur + ( * GrainDurJitter * GrainDur)
where is a random number between -1 and 1.
