Pencil-expressive. Fingers welcome.

Every hit is unique. Apple Pencil's 6 continuous dimensions at 240Hz turn each strike into a living, expressive event. No other drum instrument captures this level of continuous gestural nuance.

$9.99 launch price $14.99

Per-Hit Expression

Force controls velocity and harmonic intensity. Tilt shapes decay time — steep angle for short attack, flat for long sustain. Position tunes pitch ±1 octave (X) and sweeps filter cutoff (Y). Roll (Pencil Pro) modulates noise color and filter character. Every dimension is captured per step and reproduced on playback.

Post-Strike Gestures

Flick up triggers a bandpass sweep. Flick down chokes instantly. Left/right bends pitch ±0.5 octave. Drawn contours let you sketch custom amplitude envelopes directly on each pad with the pencil tip. High-speed flicks fire ghost retriggers at 25% velocity.

Only synthesis. No samples.

Every sound is generated in real-time from mathematical models of analog drum circuits. 4 exciter types, 3 filter types, 25+ parameters per voice. 20 factory kits. 240 voice presets. All generated, never recorded.
