• Import Image to Brush: Opens a dialog where you can select a file in PNG format to
be used as a brush for painting on the spectral canvas. The original dimensions of
the image are preserved. You can place the image at any position with a click, or you
can drag to paint with it.
• Clear button: Deletes all spectral data from the source, leaving only silence (a solid
black image).
• Scroll bar and zoom controls: Drag the middle of the scroll bar to view spectral data
that is 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.
Alchemy main filters
Logic Pro Alchemy main filter controls
Main filter components are shown only in advanced view. Click the Advanced button to
switch to advanced view, then click the Global button.
There are two main filter modules, labeled Filter 1 and Filter 2. The filters can operate in
parallel or in series.
The output from all four sources is sent to the main filters at levels determined by
independent controls in each source. Both main filter modules provide multi-mode filters
with identical controls.
Note: It is possible for each source to completely bypass the main filters, or to send a
portion of the source signal to the main filters and another portion directly to the effects
section. Though you can use filters at multiple locations in the signal path, you can often
attain the same or similar results by careful use of fewer filters, which helps to reduce
CPU load.
