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. AUv3 MIDI Effect - Works in AUv3 hosts such as AUM, Drambo, Logic, and Cubasis - MIDI-only design compatible with any synth or sampler

Eight tracks. Synths, samplers, drums. Play it like an instrument. ARC-24 is a groovebox for iPhone and iPad. Pads, loops, and a mixer in one place. Everything stays in key. Pick a key and a scale and the pads follow, so you can play fast without landing on a wrong note. Record a loop, keep overdubbing while it runs, and fix whatever you fumbled on the grid afterwards. Once you've got a few loops going, chain them into a song. Or leave the transport running and fire them off by hand from the mixer. • Eight tracks that sort themselves out. Synth, sampler, or drums, decided by what you play first. Overdub while the loop cycles. • Note and chord pads locked to your key and scale. Hold latches notes so they sustain. Pulse retriggers them on the beat. • A sixteen pad sampler. Import WAV, AIFF, MP3, M4A, AAC, or FLAC, pull audio from a video, or record through the mic. Chop it into slices across the grid, or map one sample over every pad and play it pitched, in scale or chromatic, at the original length or at tape speed. • Ten drum kits, from 909 and trap to lo-fi, boom bap, and hand percussion. Tune, pan, and level every pad. • Synth editing that goes deep enough to matter. 21 presets to start from, two oscillators, filter, envelope, and LFO when you want to build your own. Save the keepers. • 25 arpeggiator patterns, all of them in your key, from slow drifting phrases to sixteenth note runs. • A piano roll editor. Move, stretch, and delete notes while the loop keeps playing. • A real mixer. Faders, pan, mute, solo, and three band EQ on every channel. • Every track gets its own effects rack, not a shared send. Resonant low and high pass with cutoff and resonance. Compressor and gate. Distortion, bit crusher, ring mod, flanger. Tempo synced delay in digital, analog, or tape. Reverb with chorus and tape wow. Character for texture, air, width, and warmth. • Motion, so synth parts never sit still. Slow LFOs drift the filter as the loop runs, and Bloom opens the cutoff every time you play a note. • Song mode. Arrange loops into sections, or switch between them live from the mixer without ever stopping. • MIDI in from a USB or Bluetooth controller. • Export to WAV or AAC. • iCloud. Start something on the iPad, pick it up on the phone. Seven days free, the whole app. After that one purchase unlocks it for good. No subscription, no renewal, nothing to cancel.
