If the settings of Loop Start and Loop Length controls (see entries above) cause
playback to go beyond the end of the underlying sample, silence is automatically
inserted at the end of the sound.
All: Ignores the loop start and end points, and loops the entire sound continuously.
Note: The loop start and the loop end points, and sample start and end points,
can be edited in the Main edit window. See Logic Pro Alchemy source edit window
overview and Logic Pro Alchemy zone waveform editor. The VA noise component is
not affected by the Loop mode setting.
Waveform overview display: Shows the waveform for the source when the granular
or sampler element button is active. The display also shows real-time additive or
spectral data, or a representation of the waveform, if the Position or Speed controls are
selected. When Position is adjusted, a position indicator is shown, allowing you to fine-
tune the start position.
Synthesis element buttons: Choose the synthesis type, and view and change related
parameters in the area below. A variable combination of the Additive, Spectral, Pitch,
Formant, Granular, Sampler, and VA buttons is available for use, depending on the audio
data specified in the source select field and the import method used, if applicable. See
Logic Pro Alchemy source elements overview and Logic Pro Alchemy Import browser.
Logic Pro Alchemy source filters
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.
The source filter module provides three multimode filters, which can be configured either
in series or in parallel. The source filters let you filter each source independently. The main
filters, by comparison, process a mix of all four sources. See Logic Pro Alchemy main filter
controls.
Tip: Though you can use filters at multiple locations in the signal path, you can attain
identical or similar results by careful use of fewer filters, which helps to reduce CPU load.
When the source filters are configured in series, the signal passes through the three
filters, one after the other.
