Arpeggiator

Up: the chord notes from lowest to highest, then back to the bottom to start again.

Pattern: A3, C4, E4, then the pattern starts over. At 1/16, you hear four notes per beat. The length of each note, called the gate, is 60% of the step: the shorter it is, the drier and bouncier the pattern sounds.

The pattern has 3 notes while a bar has 16 steps: it does not land in the same place every bar, which creates a shifting, rolling feel.
