• Loop and warp markers can be superimposed on the Partial envelope. See Logic Pro
Alchemy zone waveform editor.
• Warp marker movements automatically snap to existing Partial envelope points.
• Positioning the loop start and loop end markers at identical positions creates a
sustain point which allows a particular segment of the sound (a snapshot) to be
heard continuously. This method is useful for locating, auditioning, and editing a
succession of snapshots.
• Scroll bar and zoom controls: Drag the middle of the scroll bar to view envelope points
that are not visible in the display area. Horizontally drag the zoom controls at either end
of the scroll bar to resize the contents of the visible display area.
Create or delete points in the partial envelope
In Logic Pro, do one of the following:
• Click anywhere in the Partial envelope to create a new point for the active partial
(selected in the Partial number bar).
• Click on or near a line between existing points to create a new point.
When the Partial envelope contains existing points, either method creates a snapshot of
partial values that fall in between the partial values associated with the preceding and
following points.
If the Partial envelope is “blank” (only contains a single point), each newly-created point
has a single associated partial value (for the partial selected in the Partial number bar).
The partial (value) of the preceding point is also shown in the Partial bar display.
Note: The Overall button affects the display of values shown in the Partial bar and
related points in the Partial envelope.
• Double-click an envelope point to delete it.
Adjust partial pitch values with partial envelope points
When the additive editor displays pitch (the Tune button is on), point levels represent
partial pitches. You can edit these levels to eliminate a pitch wobble or to create vibrato,
for example.
1. In Logic Pro, click an envelope point to select it. You can also drag across multiple
envelope points to select them.
This selects a snapshot of multiple partials when the Overall button is on, or individual
partials when the Overall button is off.
When multiple points are selected, the Partial bar shows the average value of each
partial across the selected envelope points. Edits of partial values are applied to all
partials associated with the selected points.
2. Click the Tune button above the Partial bar display to view pitch values at the current
envelope point.
3. If required, click the Mode pop-up menu above the Partial bar to choose how your edits
are applied: to a single partial, all partials, or a group of related partials.
4. Drag the envelope point vertically to set the pitch value.
The time and pitch of the selected point are displayed at the pointer position when
clicked.
