The Kyma Language for Sound Design, Version 4.5

Random Numbers
random is a message sent to a time. It generates a new random number between -1 and 1 at the periodic
rate. For example,
2 s random
would generate a new number once every 2 seconds.
nextRandom is typically sent to an Event Value that is acting as a trigger. It generates a random number
between -1 and 1 each time the trigger becomes positive. For example,
!KeyDown nextRandom
would generate a new random number each time you pressed a key on the MIDI keyboard.
Smoothing
There are two operations that smooth out or filter the changes between sequential real-time expression
values.
!Fader1 smooth: 2 s
will take two seconds to get from the old value of !Fader1 to its new value, rather than jumping instantly
to its new value.
!Fader1 smoothed
will use a default value of 100 milliseconds as the time it takes to get from the old value to the new value.
For example, to add portamento to a Sound, you can smooth its frequency parameter using
!Pitch smoothed
or,
!Pitch smooth: 25 ms
for a quicker portamento.
Virtual Control Surface
To open the virtual control surface, choose Virtual control surface from the File menu. § The virtual control
surface allows you to monitor and control Event Values in the currently loaded Sound. The virtual
control surface is global; it will change whenever you load a different Sound.
The faders, toggles and gates in the virtual control surface serve two functions: they can be used to control
Event Values directly from the virtual control surface; they also display any changes made to the
§ By default, Kyma opens the virtual control surface automatically for you whenever a Sound is played, see
Performance… on page 430.
