Riff Constructor
Build a multi-bar riff by chaining Music Phrase cells. Mix variations of the same shape, layer a drum groove underneath, and loop seamlessly. A small in-browser editor that turns the catalog into a groove generator.
Click an empty bar to pick a phrase from the catalog. Cells get a fresh shuffle each insert; the re-shuffle button rolls a new rhythm. Gestures play as written.
Choose a drum pattern below, set BPM · Key · Octave, then hit Play. The global loop button in the bottom-right toggles seamless looping.
