Dr. Fill

Dr. Fill by Basic Wavez is a drum fill generator designed to rescue your transitions from last-minute guesswork. Whether your track needs a quick snare roll, a tom cascade, or a percussion break, one click produces a fill that fits naturally. You can tweak density, swing, and humanize for a looser or tighter feel, or randomize until something clicks. Pattern Lock holds a rhythm you like while you audition new sounds, and Kit Builder lets you load your own samples—drums, vocal chops, bass hits, textures—with automatic sample-type and key detection keeping everything organized and in tune. Drag fills straight into your DAW, export MIDI, or trigger Dr. Fill with MIDI input. Choose half-bar, one-bar, or two-bar lengths and shape results with snare, tom, crash, and variation controls. It suits hobby producers in FL Studio, Ableton, or Logic who want fast, intentional-sounding transitions without overthinking.
