Use the Beat Sequencer in GarageBand for iPad
You can create repeating drum patterns with the Beat Sequencer by tapping squares or steps in a grid. Each grid row controls a different drum sound (kit piece), and each column represents a beat in the pattern. When the Beat Sequencer is on (running), each lit step plays its corresponding sound. You can choose different drum sounds and patterns, and adjust velocity and other settings to customize the pattern.
Tap the Browser button , swipe to Drums, then tap the Beat Sequencer button.
The Beat Sequencer comes with many drum patterns that you can change and save.
Tap the Patterns button under the Beat Sequencer, then tap a pattern shown in the list.
