The Kyma Language for Sound Design, Version 4.5

Polyphony
Number of simultaneous MIDI note events possible on this voice. For example, if you specify a
Polyphony value of 4, Kyma makes 4 copies of the Input Sound, so any one of them can be triggered at
any time and all four can be sounding at the same time. The higher the value of Polyphony, the more
computation time is required per sample tick.
LowPitch
The lowest MIDI pitch that this voice responds to. Be sure to include units of pitch or frequency with the
value. (For this particular Sound, if you specify this value as a frequency, Kyma will round to the nearest
equal-tempered MIDI notenumber).
This allows you to map different regions of the MIDI note range to different voices and to define keyboard
splits.
HighPitch
The highest MIDI pitch that this voice responds to. Be sure to include units of pitch or frequency with the
value. (For this particular Sound, if you specify this value as a frequency, Kyma will round to the nearest
equal-tempered MIDI notenumber).
This allows you to map different regions of the MIDI note range to different voices and to define keyboard
splits.
Script
When Source is set to Script, this program sends MIDI events to the Input (just as if these events were
being read from a MIDI file). See the manual for more information on algorithmically generating and
manipulating MIDI events.
To specify a MIDI event, use:
self keyDownAt: duration: frequency: velocity: .
Be sure to include units on the start time, duration, and frequency values, and specify velocity within a
range of 0 to 1. Frequency can be any value specified in hz or nn; you are not limited to the pitches from
the 12-tone equal tempered scale. All arguments must be real values (as opposed to EventValues).
As a shortcut, you can drop any of the tags, for example, the following are all valid:
self keyDownAt: 0 s.
self keyDownAt: 3 s duration: 10 beats.
self keyDownAt: 0 beats duration: 10 beats frequency: 4 c.
self keyDownAt: 5 beats duration: 0.25 beats frequency: 4 c + 0.5 nn velocity: 0.75.
This field is actually a Smalltalk program, so you can use Smalltalk expressions or control structures to
generate these events algorithmically, for example:
1 to: 12 do: [ :i |
self keyDownAt: (i - 1) beats duration: 0.25 beats frequency: 4 c + i nn velocity: (i / 12.0)].
or:
| r t |
r := Random newForKymaWithSeed: 66508.
t := 0.
100 timesRepeat: [
t := t + r next.
self keyDownAt: t s duration: 0.25 beats frequency: (r next * 1000 + 60) hz velocity: r next].
You can also create sequences and mixes of "notes" and "rests" or collections of MIDI events, each
associated with its own time tag.
To create a rest object, use:
