The Kyma Language for Sound Design, Version 4.5

ScaleVocoder
Filters Category
Vocoder whose center frequencies are tuned to a base pitch and a scale.
Input
This is the source material to be filtered by the SideChain-controlled filters. This Sound is heard directly,
through the filters (whereas the SideChain is never heard directly). For example, if you want to make an
animal talk, put a sample of the animal sound here and put a sample of speech (or use a microphone) as
the SideChain.
The best Inputs tend to be fairly broad band signals that have energy in each of the frequency bands
covered by the resynthesis filter bank. For example, Noise or an Oscillator on a waveform with lots of
harmonics (such as Buzz128) will work well because they generate energy over the full frequency range.
SideChain
Sometimes referred to as the "modulation", this Sound is never heard directly; it controls the amplitudes
of the filters in the bank.
TimeConstant
This determines how quickly the amplitude envelopes on the filters will respond to changes in the
SideChain. For precise, intelligible results, use values less than 0.1 s. For a more diffuse, reverberated
result, use a longer TimeConstant.
NbrBands
This is the number of band pass filters in the filter bank.
BankSize
This is the number of filters per processor. Type
default
to get the standard number of filters per processor. If you are running out of time, try reducing the default
size, for example
default * 0.75
Tonic
This is the tonic or first pitch in the scale.
Intervals
This is the interval pattern of the scale in half steps. For example, a major scale would be
0 2 4 5 7 9 11
Arithmetic expressions should be enclosed in curly braces, for example
{!SmallInterval1 rounded nn}
The scale can have any number of steps, and the steps are repeated in each octave for as many bands
as you have specified.
