How to use it
- Click squares on the grid to place hits. Every fourth square is shaded to mark the beats.
- Press Play or the space bar. The current step is outlined.
- Set the Tempo and Swing, or load a preset and change it.
- Click a drum name or press 1 to 8 to hear it on its own.
How it works
Steps are booked a short time ahead on the audio clock, so the rhythm stays steady even when the page is busy. One step lasts 60 ÷ BPM ÷ 4 seconds. The pattern is a loop of 16 steps, one bar of 4/4.
Worked example
At 90 BPM a step lasts 60 ÷ 90 ÷ 4 = 0.1667 s, and the bar lasts 2.67 s. Kick on steps 1, 5, 9 and 13 gives a four-on-the-floor beat.
Tips
- Start with kick and snare, then add hats; fewer hits often sound better.
- On a phone, slide the grid sideways to reach the last steps.
