Note: Higher partials that are part of the additive data set may not be heard unless the
Num Partials (number of partials) control on the respective source A/B/C/D subpage is set
to a suitably high value. For example, raising the amplitude of partial number 72 has no
effect when Num Partials is set to a value of 60. Conversely, setting a Num Partials value of
500 has no effect in additive mode unless partial data exists for 500 partials.
Partial bar display parameters
Overall button: Use in conjunction with the Vol, Tune, Pan, and Phase buttons to display
partial values averaged across all envelope points. When the Phase button is active, the
Partial envelope only is updated.
Turn on Overall to adjust the amplitude, pitch, and pan values of all partials across
the entire sound, without the need to select and edit individual envelope points for
each partial. Also see the Overall button information for the Logic Pro Alchemy partial
envelope.
Partial display mode buttons: Click Vol, Tune, Pan, or Phase to restrict the display to the
chosen partial parameter type.
Vol button: Show partial amplitude values.
Tune button: Show partial pitch values. Also see Snap Pitch button information
below.
Pan button: Show partial pan values.
Phase button: Show partial phase values.
Mode pop-up menu and field: Choose a group of related partials for editing. You can
also click the Previous and Next buttons (the arrows) to step through modes. Group
adjustments retain the relative differences between partial values. Hold down Command
while dragging to scale adjustments logarithmically. Note that the Shape pop-up menu
affects editing behavior in each mode.
One: Adjustments affect the value of only the selected partial.
All: Adjustments affect the values of all partials.
Even: Adjustments affect the values of only even-numbered partials.
Fifths: Adjustments affect the values of only partials that are fifths apart from the
selected partial and the selected partial itself.
Octaves: Adjustments affect the values of only partials that are octaves apart from
the selected partial and the selected partial itself.
Odd: Adjustments affect the values of only odd-numbered partials.
Thirds: Adjustments affect the values of only partials that are thirds apart from the
selected partial and the selected partial itself.
