Automatic instrument recognition is approximate. It works best on isolated drum loops; full mixed songs, overlapping instruments and cymbals can be misclassified. The editor lets you correct every hit.

2. Edit beat

Click any square to add/remove a hit. Four beats per bar, four steps per beat. Import analysis quantizes the first bar into 16 steps.

3. Drum sounds

Kick · Snare · Closed Hi-hat · Open Hi-hat · Low Tom · High Tom · Clap

Synthesized drum samples are generated with Web Audio, so playback works without external audio files. Headphones recommended.
