Drums in.Sheet music out.
Upload a song and get a drum chart you can read, play along with and fix. Kick, snare, hi-hat, rack and floor tom, crash and ride, each written as its own drum.
It reads nearly 9 in 10 drum hits correctly, and we publish the number. See how it’s measured.
From track to chart in minutes.
Drop a track
Drop in an audio file: studio cut, live take, a phone recording of your own demo. Got a link? We'll try that too.
We isolate and listen
We split the drums out of the mix and run them through a model trained on real records, not loops, not MIDI.
Read, edit, play along
Get engraved, editable sheet music with a cursor locked to the audio. Fix anything, export MusicXML or MIDI.
Then practice it.
The chart opens in a player built for learning a part.
Slow it down
− / +Practice at 50% and work back up in 5% steps, until it's at tempo.
Loop the hard bar
L · IDrag across the notation to loop a fill or a section, with a one-bar count-in if you want one.
Hear just the drums
mix ⇄ drumsSwitch between the full mix and the isolated drum track to hear exactly what was played.
Click along
MA metronome that follows the song's own beats, so it stays with the band when the tempo drifts.
Fix what's off
K S H T F C RChange any note to a different drum, move it, or delete it. The chart re-engraves with your fixes.
Take it with you

Everyone transcribes drums.
We tell you how well.
nearly 9 of every 10 hits transcribed correctly
Measured August 2026 on the public MDB drum benchmark, on real songs the models never trained on, scored against expert transcriptions. Three independently trained models vote on every note, and we date the number every time it moves. We haven’t found another drum transcriber that publishes one.
Seven drums, kept apart.
Each one is written as its own drum. Rack and floor tom stay separate, and so do crash and ride.
- KKick
- SSnare
- HHi-hat
- TRack tom
- FFloor tom
- CCrash
- RRide
- letters = the editor keys
We show you the notes worth a second listen.
No transcriber is perfect. Paradiddle flags the handful of hits it was least sure about and says why, so you check those instead of combing the whole song. Keep or fix each one in a tap.
And where this is headed: your verdicts become the training data for the next model. The more it’s used, the better it gets.
