DrumShed's Fill Builder generates fills from a massive combinatorial space. Browse community fills on Explore. Or describe what you want and let AI build it.

Build from scratch, browse the community, or describe it in English. Every approach leads to playable, shareable patterns.
23,000+ stickings, 19 accent shapes, 10 voice strategies. The combinatorial space is enormous — you'll always find something new.
Browse fills shared by drummers worldwide. Filter by genre, length, complexity, and voice count. Star your favorites.
Describe the fill you hear in your head: 'linear 16th fill ending on crash.' The AI handles sticking, accents, and voicing.
Every fill opens in the pattern editor. Swap a tom for a crash, move an accent, add a ghost note. Make it yours.
Export as video, notation image, or shareable link. Publish to the community for others to discover.
Every fill renders in standard drum notation with sticking. Learn to read while you explore.
