This is an example — a whole song transcribed by DrumAnalyzer, so you can see the
result before uploading anything. Press
Play and the cursor follows the score;
Click adds a metronome that follows the record’s own tempo; the slider simplifies
the part down to a bare pulse; Shift+click a bar (or press and hold on a touch screen)
loops it. Nothing here is hand-corrected — this is the raw output.

Lanes: CY = cymbals (crash/ride/splash), HH = hi-hat (closed and open), TT = toms, SD = snare, BD = bass drum (kick).
Notation follows the standard drum-set convention: hands (cymbals, hi-hat, snare, toms) share up-stems, the kick has down-stems; the key at the top of the score shows each instrument’s staff position.
Colored ribbon — the song map: one square per measure, same color = same drum pattern. Click a square (or any bar) to jump there.
×15 above a bar — this bar repeats 15 times, marked with repeat dots 𝄆 𝄇; that is why bar numbers jump ahead. While playing, the label counts laps (7/15). ×5·2 means a two-bar phrase repeated 5 times.
Level — simplifies the drum part for practice, from L1 (bare pulse) to L5 (as recorded). The song itself always plays in full — pick your level and play along.
Synth — sounds the detected drums on top of the song; the ♫ slider sets the song volume (0 mutes the music, leaving only Synth).
Click — metronome: a click on every beat with an accent on the bar downbeat. It follows the song’s real tempo (the beat grid), so it stays in sync even when the recording breathes.
Loop — Shift+click a bar (or a ribbon square) to loop its block; on a touch screen, press and hold the bar instead. The chip in the header shows the range — tap it to stop looping.
Edit — fix the transcription: the grid unfolds bar by bar, click any cell to add or remove a hit (dashed outline marks your fixes; Synth plays the corrected part). Your fixes stay in this browser until you press ⇩ Fixes. On the website that button sends them to us, together with this song, and both are used to train the model — nothing is sent unless you press it. In a downloaded copy of the player the button saves a file instead.
