The Kyma Language for Sound Design, Version 4.5

OscilloscopeDisplay
Tracking Live Input Category
Displays the Input as an oscilloscope trace on the Virtual control surface. Use the buttons along the
bottom of the display to zoom in or out in the time or amplitude dimensions. The value at the cursor point
(where the red cross hairs meet) is displayed in the upper left. Clicking on the display freezes it so you
can hold down the mouse over specific points to read their exact values.
An Oscilloscope can be placed anywhere along the signal flow path; it does not necessarily have to be
the final Sound in a signal flow path (it could, for example, be displaying the Input to the Sound that is
actually being heard). If a Sound has more than one Oscilloscope within it, all the traces will be displayed
side by side in the Virtual control surface.
You can also view the oscilloscope trace of any Sound by selecting the Sound and then choosing
Oscilloscope from the Info menu. (But the menu method only allows you to view one Sound at a time on
the Oscilloscope and does not allow you to adjust the trigger frequency for a stable display).
Input
The amplitude of this Sound is continuously displayed on the Virtual control surface, as if by an
oscilloscope.
Trigger
In order to see a picture of the waveform that does not drift across the screen, use a PulseTrain here, and
set the repetition period of the pulses to equal the inverse of the Input’s frequency. That way, the
Oscilloscope is triggered once every Input period, and you will see a single period of the Input in the
display window.
