The pattern editor gives you full control over your drum patterns. Tap cells to cycle through off, ghost, normal, and accent. Works on iPhone and iPad.
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.
Build patterns in any meter. The grid adapts columns to match your time signature and subdivision.
The grid expands on iPad for comfortable editing. See more voices and subdivisions at once.
Kick, snare, hi-hat (open/closed/pedal), ride, crash, toms, cowbell, cross-stick — every drum kit voice.
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. Long-press to set B (both hands) for flams. Sticking overlays show in playback.
Switch between grid view and standard drum notation. Both show a moving playhead during playback. Your view preference saves with each pattern.
Red borders flag impossible hits (same hand, same tick). Yellow borders flag difficult hand crossings at dense subdivisions. Helps you build playable patterns.
Hit play to hear the pattern loop as you edit. Changes are instant — place a hit, hear it on the next loop. No save-and-reload.
