Editing Ultrabeat’s Envelopes Graphically
Ultrabeat’s envelope display provides a unique envelope design, consisting of Bezier
curves in which two segments—attack and decay—constitute the entire envelope.
Attack time handle Decay time handle
Decay curve handle
Decay curve handle
Attack curve handle Attack curve handle
In the envelope graphic, you can see various handles (junction points) of two different
sizes.
Both of the larger handles on the x-axis (the horizontal, or time axis at the bottom) control
the attack and decay times, respectively. A vertical line extends up from the first of the
two handles (attack), and divides the envelope into an attack and decay phase.
Both segments each have two small curve handles. You can drag these in any direction
to deform the contour of the envelope and freely shape its amplitude.
You can also directly drag anywhere on the curve itself to reshape the envelope.
