The Kyma Language for Sound Design, Version 4.5

ReverbSection
Reverb, Delay, Feedback Category
Same as DelayWithFeedback except that the characteristics are specified in terms of DecayTime, the
time it takes for the delayed and fed-back input to die away 60 dB below its initial level.
You can use combinations of these Sounds and others to build your own reverberation algorithms.
Type
Choose between comb and allpass filters. Both comb and allpass are delays with feedback. Allpass also
adds some of the direct signal to the output in order to make the long term frequency response flat.
Input
This signal is delayed and added to itself.
Scale
An attenuation factor on the Input (where 1 is full amplitude and 0 is completely attenuated so there is no
more Input).
DecayTime
This is the time it takes for the signal to die away to 60 dB below its original level.
Delay
The maximum delay time. The proportion of this time that is actually used is determined by multiplying
this value by DelayScale. Kyma needs to know the maximum possible delay in order to allocate some
memory for this Sound to use as a delay line, but the actual delay can vary over the course of the Sound
from 0 s up to the value of DelayTime.
DelayScale
The proportion of DelayTime that is actually used as the delay, where 0 is no delay, and 1 is equal to the
value in the DelayTime field.
Wavetable
In almost all situations, this should be set to Private, so Kyma can allocate some unused wavetable
memory to be used as a delay time for this program. (The only time you would want to name this
wavetable is if you would like multiple delays or resonators to share a single delay line. In that case, you
would type a name for the wavetable and make sure that the other delays use the same name for their
wavetables.)
Prezero
Check this box to start with an empty delay line when this program starts. If Prezero is not checked, the
delay line may have garbage in it from previous programs. This can have interesting, if unpredictable,
effects.
Interpolation
When Linear is selected, changes to DelayScale will be interpolated, causing smoother changes to the
delay.
