1. Start. Tap the green dot top left. Space bar works too.
2. Pick a mode. The next four dots switch pattern style: step, euclid, scatter, pulse. While playing, a new mode blinks and takes over at the start of the next bar.
3. Set tempo. Tap a dot in the top-right strip, 90 to 160 BPM.
4. Edit the beat. Each grid row is a drum: kick, snare, closed hat, open hat, clap, rim, tom, glitch blip. Tap a dot to toggle it. Editing a generated pattern copies it into step mode so it's yours.
5. Beat repeat. Hold a ring while it plays. Left to right repeats 1/4 to 1/32 notes. Lower rows fade and drop pitch harder. Slide between rings, let go to snap back.
6. Density. The bottom strip sets how busy every mode is, and how often hits glitch into stutters.

1. Tap a dot. It plays a note and sends out a ripple. Every dot the ripple reaches plays too, softer and duller the further it travels. Low notes are bottom left, high notes top right.
2. Cross ripples. Where two ripples meet, that dot rings out brighter and a smaller ripple starts there. Those can cross again, up to three times.
3. Drone. The green dot top left taps a random dot every few seconds. Space bar works too.
4. Scale. The next three dots: minor pentatonic, major pentatonic, Dorian.
5. Speed. The top-right strip sets how fast ripples spread.
6. Reach. The bottom strip sets how far a ripple travels before it dies out.
