Edit Step Sequencer steps in Logic Pro for iPad
You can edit individual steps in several ways, including cutting, copying, and pasting steps. You can also repeat a step, decrement or increment the values of all steps in a row, transpose all steps in a pattern by semitones or octaves, and reset steps to default values.
Pattern regions can be edited only in Step Sequencer in Logic Pro for iPad, not in the other MIDI editors. You can convert a pattern region to a MIDI region, which can be edited in the Tracks area and in the Piano Roll Editor.

in the Step Sequencer menu bar.Tap the step to select it, tap it again, then tap Cut.
When you cut a step, the step value and edit mode settings are cut, but the empty step remains in the step grid. The order of following steps does not change.
Copy and paste a step
You can copy a step, including all of its step settings. When you paste a copied step, the destination row should be of the same row type (note or automation) as the source row.

in the pattern controls until you see the Decrement and Increment buttons 
, then do one of the following:
To lower the value of all steps in the pattern: Tap the Decrement button in the pattern controls.

You can also continuously change the value for all steps in the pattern by touching and holding either button and dragging vertically.
When the edit mode is set to Step On/Off, tapping the Increment button turns on all inactive steps, and tapping Decrement button turns off all active steps. When the edit mode is set to Tie, tapping the Increment button ties all steps, and tapping the Decrement button unties all tied steps.

Reset step values to default settings
When you create a pattern in Logic Pro for iPad, many Step Sequencer settings, including all edit modes and the playback mode, have a default value. After you change the value for a step, it no longer retains the default value. You can clear steps, which resets all their edit mode values to default values (for the step rate, the default is defined by the row step rate). You can clear a single step, all steps in a row, or all steps in the pattern. You can also clear the values for the currently selected edit mode in a single row, for all note rows or all automation rows, or for steps in all rows in the pattern.
To clear edit mode values for a step: Tap the Step Select button
in the Step Sequencer menu bar, tap the step to select it, tap it again, then tap Clear Step.To clear all edit mode values for all steps in a row: Tap the row icon to select the row, tap it again, then choose Clear Row.
