This is the deep end. 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.
Every voice on a row, every subdivision on a column. Tap to cycle hit states, long-press for precise velocity.
Each cell cycles: off → ghost → normal → accent. Tap to cycle quickly, long-press to fine-tune velocity.
Any time signature from 2 to 13 over /4 or /8, with mixed subdivisions per beat. The grid adapts columns to match.
The grid expands on iPad for comfortable editing. See more voices and subdivisions at once.
20 drum voices — kick, snare, hi-hat (open/closed/pedal), ride, crash, toms, cowbell, cross-stick, and more.
Hear your pattern loop as you edit. Changes are instant — no save-and-reload.


Change the subdivision of individual beats within a bar. Mix triplets on beat 1 with 16ths on beat 2. Auto-quantize preserves existing notes.
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.
Red borders flag impossible hits (same hand, same tick). Yellow borders flag difficult hand crossings. Visual only — helps you understand what's physically realistic.
The pattern editor is the final destination for beats and fills. Everything the wizards and AI generate opens here for fine-tuning.
16ths for most grooves, triplets for jazz and shuffle, sextuplets for dense patterns, 32nds for ghost-note-heavy grooves. Mix subdivisions per beat.
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.
Toggle R/L sticking mode. Tap cells to assign right or left hand, or tap a voice label to lay a whole preset across the bar in one tap — paradiddle, doubles, alternating, or a custom pattern, on one voice or every voice at once. Ghost notes read as lowercase r/l. Long-press to set B (both hands) for flams.
Switch between grid view and standard drum notation. Toggle counting syllables — 1 e & a, triplets, sextuplets — above the staff. Both show a moving playhead during playback.
Split a beat into two halves with different subdivisions — a 16th-triplet half flowing into straight 16ths. The grid handles the math.
Go long: up to 64 bars, with an Arrange view that shows every bar as a card — drag to reorder, tap one to edit, copy, paste, duplicate, or delete a whole run. Scaffold the piece, then fill in the bars.
Export as video (five aspect ratios, click on or off), PNG notation images, or an engraved multi-page sheet-music PDF with per-bar sticking and count captions. Your name is on every export.
