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.
LFO. See Alchemy sequencer in Logic Pro for Mac.
Envelope Follower. See Alchemy note property modulators in Logic Pro for Mac.
Perform. See Alchemy wide unison mode.
In the source section, click the Vol knob for source A. In the modulation section, the Target pop-up menu changes to read Vol A.
Click in the top slot of the modulation rack, then choose LFO > LFO 1 from the pop-up menu. Click the LFO button to display the LFO controls in the area to the right of the modulation rack.
Note: The pop-up menu displays the waveform shape used by the selected LFO in parentheses. For example, “LFO 1 (Sin)” indicates that LFO 1 is using a sine waveform. The waveform shape is updated in the modulation rack when changed in an LFO. See PDF
