What is Automation?

−

Automation in Logic Pro X allows you to change settings over time, such as volume, panning, or effects parameters, to add dynamic movement to your tracks.

Key Concept: Automation creates changes in parameters automatically as your track plays, enabling you to craft evolving sounds and effects.

Volume Automation: Fade in or out (e.g., from 0 dB to -12 dB) to create smooth transitions.
Filter Automation: Sweep a filter cutoff (e.g., from 100 Hz to 5 kHz) for a dynamic effect.
Panning Automation: Move a sound across the stereo field (e.g., from left to right) for spatial movement.

Why It Matters: Automation adds life to your tracks, making them more engaging by introducing changes over time, such as a gradual build-up or a subtle fade-out.

How to Use Automation in Logic Pro X

Press A to show automation lanes, select a parameter like Volume, and draw a line to create changes over time.

Step-by-Step Guide:

Show Automation: Press A in Logic Pro X to display the automation lanes for your track.
Select Parameter: Choose the parameter to automate (e.g., Volume, Filter Cutoff, Pan) from the dropdown menu in the automation lane.
Draw Automation: Click and drag to draw points and lines (e.g., a line from 0 dB to -12 dB for a fade-out).
Adjust Points: Add more points to create curves (e.g., a gradual fade) or sharp changes (e.g., a sudden drop).

Practical Example: On a synth track, select Volume automation, draw a line from 0 dB to -12 dB over 8 bars for a fade-out, then play the track to hear the effect.

Tip: Use the automation curve tool to create smooth transitions, such as a gradual filter sweep, for a more natural sound.

Practical Examples of Automation

Try automating a filter cutoff on a synth: pick Retro Synth, add automation, and sweep from 100 Hz to 5 kHz for a dynamic effect.

Example 1: Filter Cutoff Sweep

Setup: Add Retro Synth to a track, select a sawtooth wave, and open the automation lane (press A).
Automate: Choose Filter Cutoff, draw a line from 100 Hz to 5 kHz over 4 bars to create a sweeping effect.
Result: The synth will gradually open up, creating a dynamic build-up perfect for transitions.

Example 2: Panning Automation

Setup: Add a hi-hat loop to a track and open the automation lane.
Automate: Select Pan, draw a line from -20 (left) to +20 (right) over 2 bars, then back to -20.
Result: The hi-hat will move across the stereo field, adding spatial interest to your track.

Tip: Combine multiple automations (e.g., volume and filter cutoff) on the same track for more complex effects, like a fading synth with an opening filter.

Common Automation Techniques

Automation can be used for more than just volume and filters—explore techniques like panning, effects, and more.

Technique 1: Effects Automation

Reverb Wet/Dry: Automate the wet/dry mix of a reverb (e.g., Space Designer) to increase from 0% to 50% over 4 bars, adding depth to a vocal.
Delay Feedback: Increase the feedback of a delay (e.g., from 0% to 80%) to create an echoing effect on a synth lead.

Technique 2: Panning Automation

Stereo Movement: Automate panning to move a sound across the stereo field (e.g., from -20 to +20) for a dynamic effect.
Alternating Panning: Create a ping-pong effect by alternating panning (e.g., -10 to +10 every beat) on a hi-hat.

Technique 3: Plugin Parameter Automation

Filter Resonance: Automate the resonance of a filter (e.g., from 0 to 50%) to add intensity to a synth sweep.
Distortion Drive: Increase the drive of a distortion plugin (e.g., from 0 to 10) to add grit to a bassline over time.

Troubleshooting Tip: If automation isn’t working, ensure the track is set to "Read" mode (not "Off") in the automation lane, and check that the parameter is correctly assigned.
