Logic Pro Alchemy modulation overview
Modulation components are shown only in advanced view. Click the Advanced button to
switch to advanced view.
Alchemy features a modular modulation system that combines ease of use with extensive
functionality. The modulation rack is shown at the left. See Logic Pro Alchemy modulation
rack controls. The modulator control panel occupies the center portion of the display. This
area updates dynamically to display modulation sources for the selected parameter.
Modulator panel type buttons: Click to view settings and adjust the controls of each
modulation source.
Note: Some modulation types, namely MIDI, Note property, and Perform control
modulators, don’t have a control panel in the center of the modulation section. These
modulators are set with menu items in the modulation rack.
Almost every knob in the Alchemy interface is a modulation target, representing a
parameter that can be modulated by as many as ten modulators. This not only includes
voice parameters, but also effect, arpeggiator, and performance; even other modulation
parameters can be modulation targets. Each mod rack entry may have its depth (amount it
affects the target) modulated by up to five additional modulation sources. Each modulation
depth mod entry may be further modulated by an additional modulation source.
Note: The additional layers of modulation are useful when the amount of modulation, such
as vibrato, is controlled by an envelope, MSEG, or channel aftertouch, for example. The
third layer of modulation is particularly useful for assigning velocity or the modwheel to
add expressiveness to the preceding modulation layers.
When a parameter is the target of one or more modulators, an orange modulation arc is
shown beside the blue value arc for the knob. This indicates that the knob is an active
modulation target and shows the modulation range. Parameters that are morphed and have
a modulation assignment show both an orange and a green arc around the control.
Note: The most recently clicked knob is highlighted in blue, making it easy to identify the
current target. If you switch between source subpage A to source subpage B, for example,
the highlight shifts to the corresponding knob on the new subpage. This behavior lets you
quickly assign modulations to a parameter such as Fine Tune for multiple sources.
Each modulation type is described in the linked sections. The MIDI control, Note Property,
and Perform control modulators do not have a graphical control panel.
