Place every hit
on every voice — odd meters, mixed meters, split beats.
The pattern editor gives you full control over your drum patterns. Tap cells to cycle through off, ghost, normal, and accent. Works on iPhone, iPad, and Android.
Total control over every note
Grid editor
Every voice on a row, every subdivision on a column. Tap to cycle hit states, long-press for precise velocity.
4-state tap cycle
Each cell cycles: off → ghost → normal → accent. Tap to cycle quickly, long-press to fine-tune velocity.
Odd and mixed meters
3/4, 5/4, 6/8, 7/8, mixed meters — with per-beat subdivision control. The grid adapts columns to match.
iPad optimized
The grid expands on iPad for comfortable editing. See more voices and subdivisions at once.
All voices
Kick, snare, hi-hat (open/closed/pedal), ride, crash, toms, cowbell, cross-stick — every drum kit voice.

Power features
Per-beat subdivision
Change the subdivision of individual beats within a bar. Mix triplets on beat 1 with 16ths on beat 2. Auto-quantize preserves existing notes.
Voice toggles
Toggle any drum voice on or off: kick, snare, hi-hat (open/closed/pedal), ride (bow/bell), crash, china, splash, cowbell, and all three toms.
Physical warnings
Red borders flag impossible hits (same hand, same tick). Yellow borders flag difficult hand crossings. Visual only — helps you understand what's physically realistic.
What you can build
The pattern editor is the final destination for beats and fills. Everything the wizards and AI generate opens here for fine-tuning.
Any subdivision
16ths for most grooves, triplets for jazz and shuffle, sextuplets for dense patterns, 32nds for ghost-note-heavy grooves. Mix subdivisions per beat.
Every voice
Kick, snare, hi-hat (open/closed/pedal), ride (bow/bell), crash, china, splash, cowbell, hi-tom, mid-tom, floor-tom. Toggle any voice on or off.
Sticking mode
Toggle R/L sticking mode. Tap cells to assign right or left hand. Long-press to set B (both hands) for flams. Sticking overlays show in playback.
Grid or notation
Switch between grid view and standard drum notation. Both show a moving playhead during playback. Your view preference saves with each pattern.
Half-beat splits
Split a beat into two halves with different subdivisions — a 16th-triplet half flowing into straight 16ths. The grid handles the math.
Export it
Export as video (five aspect ratios, click on or off) or PNG notation images. Your name is on every export frame.
