Create automation with Step Sequencer in Logic Pro for iPad
Instead of creating automation points along a timeline that, connected, form an automation curve, you can create automation in Logic Pro for iPad using Step Sequencer.
The concept of Step Sequencer in Logic Pro is based on classic hardware step sequencers with rows of configurable switches and knobs used to generate repeating musical patterns or drum patterns. Instead of storing notes in a series of steps along the row, you can assign a row to a specific automation parameter, and each step in that row then contains a single value for that automation parameter. See Pattern creation basics.
Creative use of Step Sequencer automation
The steps in a Step Sequencer pattern represent a specific time grid (for example, 1/16 or 1/8 notes), and storing specific values for an automation parameter (for example, pan, volume, or filter cutoff) in those steps makes it easy to create tempo-based automation. That means you can easily change the value of an automation parameter based on the bars/beats grid of your project. You need to create those automation patterns only for one bar and then extend that pattern region to repeat that pattern or move it on the track lane to any other position where you want to perform that automation.
For example:
Create 1/4 note steps for the Pan parameter to alternate left and right pan positions on the beat.
Create 1/16 note steps for one bar for the Volume parameter to decrease the level with each step gradually.
Create 1/8 note steps for two bars for the Resolution parameter of the Bitcrusher plug-in and set each step to a different value.
Create 1/2 note steps for the cutoff frequency of a synth to close and open the filter over two bars periodically.
