Lattice is a drum-pattern MIDI instrument for iOS and iPadOS that generates grooves live in your host.

Lattice is an AUv3 MIDI effect and requires a compatible host app

It does not run as a standalone instrument.

Lattice helps you find strong drum ideas quickly:

* Explore: shape patterns with an XY pad and intensity controls

* Populate Banks: capture eight patterns plus two fills from the generator

* Variations: edit strength per step (Off/Normal/Hard) and toggle hats between CH/OH

* Arrange: build chains from your captured banks for evolving patterns

* MIDI Routing: set per-lane note + channel, use routing templates, and enable Force Retrigger for tricky MIDI chains

* Deterministic output: the same controls produce the same results, so you can reliably recall what you liked

* Lattice is designed for performance workflows: changes apply at bar boundaries, playback can follow the active tab, and you can pin the top bar to lock playback to Live, a specific Pattern slot, or Chain.

Requires a compatible AUv3 host and a drum instrument to hear audio.
