The Kyma Language for Sound Design, Version 4.5

Click in a light area to draw a dark dot, and click in a dark area to draw a light dot. If you keep holding
the mouse button down while you move the mouse around, you can draw dots continuously. Sometimes
it helps to click in the zoom box of the class editor window, expanding the class editor size of the screen
in order to get a larger area for editing. Design both the large and the small icon.
Read the names listed in the Parameter field. Where have you seen these before? Apart from the name
parameter, which is shared by all Sound classes, each parameter name corresponds to the name of a variable
in the original example Sound: ?left, and Variable.
Click on Variable in the Parameter field. This is the input of the new Stereo class. To ensure that only
Sounds can be used for this parameter, select sound in the Type field. The types are listed alphabetically,
and you can use the scroll bar to scroll through the list of types.
You may have noticed that after you selected sound, the list of possible parameter field types changed.
Try selecting a different Type temporarily and watch the Field field. Only those fields that are legal for
the selected parameter type are displayed in the Field field. Make sure that you have re-selected sound
as the type for Variable.
Now modify the location for Variable in the Field Rectangle field:
0.5 @ 0 corner: 1 @ 0.8
and press Enter. This places the field in a rectangle whose upper left corner is in the middle of the editor
and flush with the top. The lower right corner is flush against the right edge and with the top of the class
name field.
The first pair of numbers is the x @ y location of the upper left of the rectangle, and the second pair of
numbers is the x @ y location of its lower right. The point 0 @ 0 is the upper left corner of the right half of
the Sound editor, and its lower right is 1 @ 1.
These numbers don’t represent specific units like pixels or centimeters; they represent the relative proportions
of a rectangle within a unit (1 by 1) rectangle. Thus, if you wanted a parameter field to take up
the bottom half of the entire area, you would specify an upper left corner of 0 @ 0.5 and a lower right
corner of 1 @ 1.
Return to the Parameter field, and select left. The value of left must lie within the range of zero to
one, so select positiveScale in the Type field. (The range for each variable type is shown in Parameter
Types and Ranges on page 540). For the Field Rectangle, enter
0 @ 0 corner: 0.5 @ 0.25
Notice how Field Layout is updated when you press the Enter key.
Select Variable in the Parameter field, and take note of how the Field Layout changes. Alternate
between selecting name, Variable, and left.
