Using Ultrabeat’s Envelope Parameters
In order to edit envelope parameters, you first need to select one of the four envelopes
with buttons 1 through 4. After this is done, the parameters of the corresponding envelope
can be changed in the envelope display window.

Buttons 1–4: Used to choose one of the four envelopes. Only the selected envelope
can be edited. The button frame of the chosen envelope is highlighted, and the envelope
display immediately updates to reflect your selection.
Attack Time handle: Defines the period of time the envelope needs to reach its maximum
value after receiving a note on message. This period is called theattack phase.
Decay Time handle: Defines the period of time the envelope needs to fall back to a 0
amplitude, after it has reached its maximum value (defined in the attack phase).
Note: You can freely change the time and shape of the envelope in the attack or decay
phase. See Editing Ultrabeat’s Envelopes Graphically.
Zoom scroll field: Resizes the visible contents of the envelope display when you drag
horizontally.
Env mod” menu: Determines the modulation target (either the time or shape of the
envelope attack or decay phase) by velocity. Choices are A Time, A Shape, D Time, or
D Shape.
“Mod” (via vel) slider: Determines the intensity of velocity modulation of the target
specified in the Env “mod” menu.
When you modulate Shape, low velocity values make the envelope sag. Higher values
make the envelope bulge.
When you modulate Time, high velocity values reduce the length of the envelope
segment. Lower velocity values increase the length of the envelope segment.
Sustain button: When active, displays a red handle (and vertical line) on the x-axis. This
can be moved horizontally—but only within the envelope decay phase. The amplitude
that the envelope reaches at the Sustain junction point is retained until the MIDI note
is released.
