Lattice

Lattice is a drum-pattern MIDI instrument for iOS and iPadOS that generates grooves live in your host. It works both as a standalone app and as an AUv3 plugin.

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.
