Logic Pro Alchemy additive element effects
Source components are shown only in advanced view. Click the Advanced button to switch
to advanced view, then click the A/B/C/D button to select the source you want to edit.
Three effects units are available in the lower half of the additive parameters shown in the
source subpage. See Logic Pro Alchemy additive element controls. These are not audio
effects in the traditional sense; rather they provide ways to control entire groups of partials
simultaneously. Each unit provides a different selection of effects. Unit 1 is devoted to
amplitude effects, unit 2 to pitch effects, and unit 3 to panning effects.
The initial configuration of the effects units changes when you use the default preset and
when you import a sample. A preset with initialized settings loads the Pulse/Saw module
into unit 1. A sound with an imported sample loads the Harmonic module into unit 1.
Note: Some effects are included only for compatibility with older Alchemy versions. These
effects are shown when a preset based on the older Alchemy architecture is loaded, but
you cannot see, nor insert, these “legacy” effects in new presets or in presets designed for
the new Alchemy architecture.
Additive effect 1 (amplitude) parameters
Additive effect on/off button: Enable or disable the additive effect unit.
Warning: Turning off additive effects modules, particularly additive effect 1, can
result in a significant level increase. It is best to turn down your amplifier or mixer levels
to avoid signal spikes that may damage your speakers or hearing.
Additive effect 1 pop-up menu and field: Choose an effect type that is used to adjust
the levels of different partial groups. Your choice determines the controls that are
shown. Choosing None results in an equal volume level for all partials, which can sound
extremely bright and harsh.
Harmonic: Allows you to set groups of partial levels.
Fundamental knob: Set the level of the fundamental tone and all partials above it.
Set to zero to completely remove the fundamental tone. Set to 100% to hear the
fundamental tone in isolation. Higher values tend to make the sound thicker.
Octaves knob: Set the level of the fundamental tone and all partials at whole
octave intervals above it. Set to zero to completely remove harmonics 1, 2, 4, 8,
16, and so on, while boosting the levels of non-octave harmonics. Set to higher
values to boost the levels of octave harmonics while reducing the levels of other
harmonics.
