Modify Step Sequencer pattern playback in Logic Pro for iPad

Some options in Step Sequencer in Logic Pro for iPad control how and when steps play back, and can be fun to manipulate while the pattern is playing. For example, you can mute and solo rows, rotate rows (moving all steps in a row left or right, including their step values and other edit mode settings), change the playback mode for the pattern or for a row, and perform other actions while the pattern is playing. There are three rows of buttons in each row header; use the Page Switch button to switch between them.

Mute a row

In Logic Pro, tap the Page Switch button in the pattern controls until you see the Mute button in the row header, then tap the button.

Solo a row

In Logic Pro, tap the Page Switch button in the pattern controls until you see the Solo button in the row header, then tap the button.

Rotate a row

When you rotate a row, all steps in the row, including their edit mode values, are shifted either left (counterclockwise) or right (clockwise). When you rotate a subrow, the edit mode value for that subrow is shifted left or right.

To rotate the row left (counterclockwise): Tap the Page Switch button in the pattern controls until you see the Rotate Left button in the row header, then tap the button.
To rotate the row right (clockwise): Tap the Page Switch button in the pattern controls until you see the Rotate Right button in the row header, then tap the button.

Rotate all steps in the pattern

In Logic Pro, do one of the following in the pattern controls:
- To rotate steps left (counterclockwise): Tap the Rotate Left button .
- To rotate steps right (clockwise): Tap the Rotate Right button .

Rotate edit mode values for steps in a row

When you use the Rotate controls in a subrow, you can rotate edit mode values for the subrow independently of the step values (on or off). You can use this technique to, for example, keep the same rhythm while changing the pitches being played.

In Logic Pro, tap the subrow disclosure arrow in a row header to show subrows for a row.
If necessary, change the edit mode for a subrow to show the one you want to rotate.
Tap the Page Switch button in the pattern controls until you see the Rotate buttons in the subrow header.
Tap the Rotate Left button or Rotate Right button in the subrow header to rotate edit mode values.

Change the playback mode for the pattern

By default, steps in a pattern sound from left to right, similar to how the playhead moves from left to right in the Tracks area. You can change the playback mode for the overall pattern and choose a different playback mode for individual rows.

In Logic Pro, tap the Page Switch button in the pattern controls until you see the Playback Mode button , then tap the button in the pattern controls and choose a playback mode.
The choices are:
- Forward: Steps play from left to right.
- Reverse: Steps play from right to left.
- Ping Pong: Playback alternates between left to right and right to left.
- Random: Steps play in an undetermined order.

You can also change the playback mode in the inspector.

Change the playback mode for a row

In Logic Pro, tap the Page Switch button in the pattern controls until you see the Playback Mode button , then tap the button in the row header and choose a playback mode.
The choices are:
- Forward: Steps play from left to right.
- Reverse: Steps play from right to left.
- Ping Pong: Playback alternates between left to right and right to left.
- Random: Steps play in an undetermined order.

Choose the transition type for an automation row

When automating a parameter on an automation row, you can choose whether the transition between steps is a sudden or gradual change.

In Logic Pro, tap the Page Switch button in the pattern controls until you see the Automation Mode button, then choose Latch or Slide in the row header.

You can also change the automation mode in the inspector.
