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.
Each of the four sources has an identical set of controls for more in-depth editing. Several
source subpage controls are duplicates of those found in the source master controls. See
Logic Pro Alchemy source master controls.
For information on source filter controls, see Logic Pro Alchemy source filters.
The waveform display and element controls section update to show relevant data and
parameters when different synthesis engines are active. The additive element is active for
source A in the image.
Source subpage controls
On/off button: Turn the source on or off.
Source select pop-up menu and field: Displays the name of the current source audio
data. Click to open a pop-up menu with source content handling commands. See Logic
Pro Alchemy source master controls.
Solo button: Isolate the source by turning off all other sources. Click again to restore
the on/off status of other sources.
Note: If you save a preset with one source in solo mode, the resulting preset retains the
on state of the source, but solo mode is disabled. All other sources are off.
Stereo button: Turn stereo mode on or off. If stereo mode is off and a stereo file is
loaded or imported, only the left channel is played. When stereo mode is on, loaded
or imported sounds are played in stereo. This makes it possible to pan individual
oscillators in the additive element or individual grains in the granular element, for
example.
Edit button: Open the source edit window. See Logic Pro Alchemy source edit window
overview.
Volume knob: Set the source output level (-inf dB to 0 dB).
Wait knob: Set a delay between the keystrike and triggering of the source.
Coarse Tune knob: Tune the source pitch in semitone increments.
Fine Tune knob: Tune the source pitch in increments of one cent (one hundredth of a
semitone).
Position knob: Determine the playback start position in the audio data. A value of 0%
indicates the absolute start point of the audio data. A value of 100% indicates the
absolute end point. See Logic Pro Alchemy source modulations.
