When row lengths are evenly divisible with one another, the overall length is equal to the
longest row. For example, if you shorten several rows in a 16-step pattern to four or eight
steps (which both divide evenly into 16), the pattern remains a one-bar pattern. When
row lengths are not evenly divisible, however, the musical length is increased (sometimes
substantially) because the pattern doesn’t repeat until all rows start at the same time
again.
Using the Skip edit mode can also result in the length of rows changing, which affects the
overall musical length of the pattern in a similar manner to changing the Loop Start/End
setting.
The playback mode can also affect the musical length of the pattern. Choosing Ping-
Pong as the playback mode doubles the pattern length, while setting any row to Random
playback mode can result in the musical length of the pattern being essentially infinite.
Ultimately, how long a pattern plays in a project depends on the length of the pattern
region or pattern cell. If the musical length of the pattern exceeds the region or cell length,
it plays only until the end of the region or cell is reached. When the region or cell length
exceeds the pattern length, the pattern repeats until the end of the region or cell, or
restarts if the region or cell is looping. If the musical length of the pattern, or of any row,
does not fit equally into the region length (or cell length), then the rows in the pattern
restart before they complete a full cycle.
Change the pattern length
In Logic Pro, choose a new length from the Pattern Length pop-up menu in the Step
Sequencer menu bar.
When you increase the pattern length, the added steps duplicate the existing pattern. You
can edit the added steps to add variation or change the pattern.
When the pattern length is more than 16 beats, the entire pattern may not be visible in the
step grid, depending on the zoom level. In this case, the pattern is divided into sections
called pages, each showing a part of the complete pattern. An overview of each page
appears above the step grid. You can click the page overviews to quickly switch between
different parts of the pattern.
You can also change the pattern length in the Step Sequencer inspector.
