Complex: A variety of complex cycles, sweeps, and patterns can be used to create
regular (and irregular) patterns for your LFO modulations.
Random Patterns: A variety of complex patterns that can be used to create random
LFO modulations.
Serial-Angular: A variety of stepped shapes.
Serial-Smooth: Provides complex rising-and-falling patterns.
Ultra High Frequency: The ultra-high frequency category waveform shapes contain
multiple copies of a pattern. The modulation speed is a multiple of the speed set
with the Rate control.
Delay knob: Introduce a delay between the note-on message and the first cycle of
the LFO when Trigger is on. When Trigger is off, Delay has no effect. The delay time
is adjustable over a range of 0.00 seconds to 20.00 seconds, or is set in tempo-
synchronized divisions when Sync is enabled.
Attack knob: Fade in the LFO output to increase modulation depth the longer a note
is held (when Trigger is on). When Trigger is off, Attack has no effect. The attack
time is adjustable over a range of 0.00 seconds to 20.00 seconds, or is set in tempo-
synchronized divisions when Sync is enabled.
Phase knob: Adjust the start point of the LFO from zero to later in the cycle (when
Trigger is on). The available range is 0.00% to 100.00%.
Rate knob: Set the LFO rate or frequency. When Sync is off, rate is adjustable from 0 Hz
to 220 Hz. With Sync on, rate is set in beats and sub-beats.
Sync button: Turn on to synchronize the LFO Rate, Attack, and Decay controls with the
project tempo. Turn off to freely set the LFO speed, attack and decay times.
Waveform window: Shows real-time changes to the LFO waveform.
Logic Pro Alchemy AHDSR envelopes
Modulation components are shown only in advanced view. Click the Advanced button to
switch to advanced view.
The AHDSR module provides an envelope generator with Attack, Hold, Decay, Sustain, and
Release stages. The A, H, D, and R times can be set independently. You can set the level of
the S stage which is maintained until a MIDI note off message is received.
The AHDSR display shows a graph of envelope generator output. The ruler along the top
shows the time, calibrated in seconds or in beats when Sync is activated. The envelope
appears as series of points joined by lines or curves representing the different envelope
segments.
You can set AHDSR values with the controls outlined in this section or by dragging points
on the envelope graphic.
