Ultrabeat envelope parameters
To edit envelope parameters, you rst need to select one of the four envelopes with the 1-4
buttons. The parameters of the corresponding envelope can then be changed in the envelope
display window.

Envelope parameters
•
Buttons 1–4: Click to select 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 reect your selection.
•
Attack time handle: Drag to set the time it takes for the envelope to reach its maximum value
after receiving a note-on message. This period is called the attack phase.
•
Decay time handle: Drag to set the time it takes for the envelope to fall to an amplitude of zero,
after it has reached its maximum value (dened in the attack phase).
•
Zoom scroll eld: Drag horizontally to resize the visible contents of the envelope display.
•
Env mod pop-up menu: Choose 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, and D Shape.
•
Mod (via vel) slider: Drag to set the intensity of velocity modulation (of the target specied in
the Env mod pop-up menu).
•
When you modulate Shape, low velocity values make the envelope concave. Higher values
make the envelope convex.
•
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: Click to turn on and display a red handle (and vertical line) on the x-axis. This
handle can be dragged 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.
Note: If the Sustain button is not turned on, the envelope functions in one-shot mode, and
the note length (MIDI note-o command) is disregarded.
•
Zoom (to t) button: Click to enlarge the envelope to ll the entire width of the envelope
display. This makes it easier to adjust junction points and curves.
Note: When the Zoom function is turned on, the decay handle can be dragged beyond the
right edge of the envelope display area, enabling you to lengthen the decay time. After you
release the mouse button, the envelope graphic is automatically resized to t the display area.
•
Zoom A/D buttons: Click to show only the attack (A) or decay (D) phase across the entire width
of the envelope display. This enables you to perform more accurate edits to envelope shapes
(down to millisecond values).
