Create an MSEG modulation routing for pitch control
Though this example is specific to pitch modulation, you can follow these steps to create a
modulation routing for other parameters such as Pan or filter Cutoff.
1. In Logic Pro, from the Name bar, click File then choose Initialize Preset to initialize the
preset.
2. In the master voice section, click the Coarse Tune knob, and assign MSEG 1 as its
modulator.
3. In the modulation rack, set the MSEG 1 Depth control to 24 semitones.
4. If the MSEG control panel is not visible, click the MSEG button at the top of the
modulation section.
5. From the Snap Y pop-up menu, choose 1/24.
Now an MSEG envelope can be used to control pitch in semitone increments, over a
two-octave (a 24 semitone) range.
Logic Pro Alchemy sequencer
Modulation components are shown only in advanced view. Click the Advanced button to
switch to advanced view.
The sequencer module is a programmable step-based modulator that can play patterns
of up to 128 steps that are synchronized with the project tempo. The level of each step,
groove/swing, and envelope can be controlled globally for the pattern and per step.
Alchemy sequencer controls
Current sequencer pop-up menu and field: Access each Sequencer control panel
by choosing a number from the pop-up menu or with the Previous and Next arrows.
Alchemy provides up to 16 sequencers—one by default, but more if you create them
when assigning modulators.
Trigger pop-up menu: Choose On to play the sequencer pattern from the beginning
with each MIDI note-on. Off makes the sequencer run continuously. Voice On/FX
Off modulates voice parameters only, not effects. The sequencer module is always
synchronized with the Logic Pro tempo, regardless of the Trigger setting.
Note: Settings from earlier application versions may not behave as expected because
of the additional trigger option. Change to VoiceOn/FX Off to match the former version
behavior, then resave the setting.
Rate pop-up menu and field: Set the duration of every step in the sequencer pattern,
expressed as a fraction of a beat. For example, assuming a quarter-note beat, a value
of 1/2 produces eighth note steps and a value of 1/4 produces sixteenth note steps. You
can also step through Rate values with the Previous and Next buttons (the arrows).
