Write automation in real time in Logic Pro for iPad
Writing automation in real time means changing the controls in a channel strip or plug-in while playing back your project and recording those changes as automation data. For example, say you increase the volume of the vocal track during the chorus or mute the drum track at a specific bar. After that, whenever you play back (or bounce) your project, those parameter changes are performed automatically.
The automation data is written as track automation or region automation, depending on the selection in the Automation Mode pop-up menu.
Automation modes
There are several automation modes that determine whether to play existing automation or not, or what happens to any existing automation data when you write new automation.
Each track can be set independently to one of the following automation modes:
Read: Plays back all automation data that exists on the track (track automation and region automation). Any onscreen control in the track header, channel strip, or plug-ins (sliders, knobs, and switches) will move accordingly during playback (in Play mode or Record mode) based on automation data. When you stop playback, you can change the value of any parameter, but once you start playback, the control jumps back to follow the values of the existing automation data.
Touch: Plays back automation in the same way as Read mode. However, once you touch a control, that parameter now writes that new value based on your movements, overwriting any existing automation data. After you release the fader or knob, the parameter follows existing automation again. You can then touch the same control or a different control to write or overwrite another section in your project.
Latch: Works like Touch mode, but after the fader or knob is released (while still playing back the project), that value continues to be written, replacing existing automation for that automation parameter until you stop playback. From that point on, the existing automation remains unchanged.
Off: Temporarily turns off all existing automation data, track automation, and region automation. The automation curves turn gray. This is useful when you have already written automation but want to experiment with parameter changes without overwriting existing data.
Note: Selecting Touch or Latch in the Tracks area creates track automation, and selecting Touch or Latch in the Editors area creates region automation. The Mixer and Plug-ins area have separate Region and Track options for Touch and Latch.
