Automating panning in Logic Pro for iPad involves using the Volume and Pan controls, which have two automation parameters: Absolute and Relative (±). These parameters represent two separate automation curves that produce a combined automation result. The Absolute automation curve is the default, determining value changes over time, while the Relative automation curve is a separate option in the pop-up menu, displaying its own automation curve with a default value of 0. Relative volume and pan automation points can be added manually, creating a complex curve to automate the volume of a vocal track or a fade-out effect while maintaining the absolute curve.

| Automation curve | Absolute automation curve is the default automation that determines the value changes for the volume or pan parameter over time |
| Relative automation curve | Available as a separate option in the Automation Parameter pop-up menu as “Volume (±)” and “Pan (±)”; functions as an offset for the corresponding absolute automation curve |
| Default value of relative automation curve | 0, which means it has no effect on the absolute parameter |

Volume and Pan controls have Absolute and Relative automation parameters
Volume and Pan controls on a track have two automation parameters, Absolute and Relative (±), that you can choose from the Automation Parameter pop-up menu. They represent two separate automation curves that together produce the combined automation result for that control. The absolute automation curve is the default automation that determines the value changes for the volume or pan parameter over time. When selected, absolute volume and pan parameters are displayed in the track header as Volume and Pan.
The relative automation curve is available as a separate option in the Automation Parameter pop-up menu as “Volume (±)” and “Pan (±)”. When selected, relative volume and pan parameters are displayed as “± Volume” and “± Pan”. By default, its value is 0, which means it has no effect on the absolute parameter. You can add automation points and edit them the same way as any other automation points. This relative curve then functions as an offset for the corresponding absolute automation curve.
Relative automation is only available for the following parameters: Volume, Pan, and Send level. Relative automation adds a secondary automation curve that offsets the existing primary curve for the selected parameter. When both relative and absolute automation exists for one of these parameters, both curves are visible and can be edited separately.
If you’ve created a complex curve to automate the volume of a vocal track, you can create a relative automation curve—for example, a straight line at –3 dB. The result will be the movement of the absolute curve, played back 3 dB lower. Or you can create a fade-out with the relative curve while maintaining the absolute automation curve you might have created for the volume parameter.

Absolute automation is the default, controlling value changes over time
When it comes to panning and volume control in Logic Pro for iPad, the automation parameters offer two options: Absolute and Relative (±). These parameters work together to produce a combined automation result.
Absolute automation is the default setting, and it controls value changes over time. This means that the absolute automation curve determines how the volume or pan parameter evolves throughout the track. The absolute volume and pan parameters are displayed simply as "Volume" and "Pan" in the track header when selected.
Absolute automation is powerful because it allows you to define how the volume or panning of a track changes from start to finish. For example, you could create an absolute automation curve that gradually pans a vocal track from the left to the right speaker over the duration of the song. This curve could also be used to automate volume changes, ensuring a smooth and consistent increase or decrease in volume over time.
Absolute automation serves as the foundation for your volume and panning adjustments. Any relative automation curves that you add will then act as offsets to this absolute curve, allowing for more nuanced and complex adjustments. By understanding and utilising absolute automation effectively, you can create dynamic and captivating audio experiences.

Relative automation is a separate option, displayed as Volume (±) and Pan (±)
When automating panning in Logic Pro for iPad, you can choose between two automation parameters for the Volume and Pan controls on a track: Absolute and Relative (±). These parameters represent two separate automation curves that, together, produce the combined automation result for that control.
The absolute automation curve is the default automation that determines the value changes for the volume or pan parameter over time. The relative automation curve, on the other hand, is a separate option displayed as "Volume (±)" and "Pan (±)" in the Automation Parameter pop-up menu. When selected, it shows its own automation curve. By default, its value is set to 0, which means it has no impact on the absolute parameter.
You can manually add and edit automation points on the relative curve, just like you would with any other automation points. This relative curve then acts as an offset for the corresponding absolute automation curve. For example, if you've created a complex curve to automate the volume of a vocal track, you can create a relative automation curve, such as a straight line at –3 dB. This will result in the absolute curve being played back 3 dB lower. Alternatively, you can create a fade-out with the relative curve while maintaining the absolute automation curve.
It's important to note that relative volume and pan automation can only be created by manually adding points. Writing automation in real time will always result in absolute volume and pan automation. The absolute volume and pan parameters are displayed as "Volume" and "Pan" in the track header, while the relative volume and pan parameters are shown as "± Volume" and "± Pan". To access automation, tap the Automation View button in the Tracks area menu bar (for track automation) or the Editors area menu bar (for region automation), or simply press "A" on your external keyboard.

Relative automation functions as an offset for the corresponding absolute automation
When using Logic Pro for iPad, you can create relative volume and pan automation. The relative automation curve is available as a separate option in the Automation Parameter pop-up menu as “Volume (±)” and “Pan (±)”. By default, its value is 0, which means it has no effect on the absolute parameter.
You can also create a fade-out with the relative curve while maintaining the absolute automation curve you might have created for the volume parameter. This allows you to adjust the overall level of your automated track while preserving the relative, automated changes.
To record relative automation, follow these steps:
- Record some absolute (regular/classic) volume automation during playback.
- Switch the volume automation lane view to relative; change the channel automation mode to touch.
- Click the relative volume automation view once to activate it (create a single automation point at the very beginning).
- Adjust the relative volume offset (automation) for the whole track while paused by moving the channel fader.

Absolute and relative automation points can be added and edited in the same way
Logic Pro offers both Absolute and Relative modes for automating the fader. Absolute and relative automation points can be added and edited in the same way. The difference between the two lies in the movement of the automation points.
If you grab a connecting line between the automation points, the movement is 'absolute', meaning all nodes move up or down by the same amount. On the other hand, if you grab a node and move the group, the movement is 'relative', resulting in the nodes moving by different amounts, with those towards the extremes moving less.
To achieve relative volume automation in Logic Pro, select volume>+-. This allows you to automate relative volume in touch mode, creating an additional volume automation lane. However, this is restricted to decibels, limiting the possible positions of the volume slider with excessive modulation.
When working with automation, it is beneficial to have both absolute and relative options. For instance, you can use absolute automation for detailed volume riding and then slowly fade out the entire section using the relative lane.
