The Kyma Language for Sound Design, Version 4.5

An envelope breakpoint field is used in the GraphicalEnvelope Sound. Time is displayed horizontally, and
the envelope value (between 0 and 1) is displayed vertically. The heavy lines indicate one second
boundaries, the thin lines are one-tenth of a second apart. The duration of each segment is scaled by the
inverse of the value in the Rate field. For example, if Rate is 0.5, then the heavy lines are two seconds
apart. Use Zoom in and Zoom out from the Edit menu to change the magnification of the display.
To select a breakpoint, click the mouse on a square marker; the selected breakpoint is always shown as a
hollow square, and its location is shown in the upper right. To add a breakpoint, click the mouse at the
new breakpoint location while holding down the Shift key. To remove a breakpoint, select the breakpoint
and press the Delete or Backspace key. To move a breakpoint, click on the breakpoint and drag it to its
new location; the coordinates of the breakpoint will be displayed as you move it around.
Breakpoints with arrows within them indicate loop points for the envelope. To add or remove a loop
point, select a breakpoint and click on the loop button at the lower right of the field. The behavior of the
envelope when there are right and left loop points is as follows
Right Left Action
no no no looping
no yes illegal
yes no on trigger off, jumps to right-arrow breakpoint
yes yes if trigger on, jumps to right-arrow breakpoint upon reaching left-arrow breakpoint;
on trigger off, jumps to left-arrow breakpoint
An input field accepts Sounds that are to be used as signal input or inputs to the edited Sound. Some input
fields will accept an arbitrary number of Sounds. Other Sound fields place some restrictions on the number
or kinds of Sounds they will accept.
You can drag Sounds into and out of input fields, as well as use any of the operations in the Edit menu
(when the input field is active, that is, when it has the black border drawn within it). Selecting one or
more Sounds and pressing Delete or Backspace is a quick way to remove Sounds from an input field.
In Sounds where the ordering of inputs is important (Concatenation, for example), the inputs are arranged
within the parameter field from left to right and from top to bottom. To change the order of the
inputs, change their positions in the parameter field.
Sounds in input fields (as well as Sounds used as control signals in other parameter fields) also show up
in the signal flow diagram. Remember to double click a different Sound (or double click in the background
of the signal flow diagram) to update the signal flow diagram after making changes to an input
parameter field.
