Sync and ms buttons: Select either a tempo-synced envelope with note value options,
such as 1/8 or 1/4, or a free-running envelope (with segment times displayed in
milliseconds).
Note: Switching between values forces a recalculation of times to the nearest note
value or ms time, respectively, based on the current project tempo.
Compare button: Toggle between the original recording and the edited version.
Note: This is available as an option only if an envelope curve has actually been recorded
and edited.
VariMod source and amount: Controls the strength of envelope variation with a user-
defined modulation source (available only for recorded envelopes).
Source options include Off, Velocity Concave, Velocity, Velocity Convex, KeyScale,
CtrlA, and CtrlB.
Variation in the envelopes means the deviation of a recorded envelope path from
straight interconnecting lines between the points. After you record an envelope,
you can reduce or exaggerate the amplitude-jitter (variation) of the recording
by Command-dragging the curves between points down (to reduce) or up (to
exaggerate).
Logic Pro Sculpture envelope display
The envelope curve is shown in the display to the lower right of the Sculpture interface.
The envelope display is active only if the envelope is engaged (Mode buttons are set to
either Env or Ctrl+Env).
The overall time/length of the envelope is indicated by the numerical entry at the top
right of the window (2400ms in the figure).
The maximum time/length of the envelope is 48 bars/40 seconds.
The lines on the background grid are placed 100milliseconds apart.
The background lines are placed 1000ms apart when very long envelope times are
displayed. In sync mode, this is displayed as 1quarter.
The envelope is zoomed automatically after you release the mouse button. This displays
the entire envelope at the highest possible resolution. You can disable or enable this
feature by clicking the Autozoom button—the small magnifying glass.
Autozoom is automatically disabled when you perform a manual zoom—by clicking the
envelope display background, and dragging horizontally. As a reference, the current
display width is displayed in the numerical entry at the top right of the display. You can
re-engage automatic zooming by clicking the Autozoom button.
