## Description

OCTACHRON is a highly flexible MIDI drum sequencer for iOS. It supports up to 16 mutable tracks, 1-32 steps, swing, and 8 chainable patterns, plus pattern presets and extensive MIDI CC modulation. It runs standalone or as an AUv3 plugin in your favorite DAW or host (AUM, Logic Pro, Cubasis, BeatMaker and more), with a focus on deep MIDI sequencing rather than generating sounds.

Designed for percussion and melodic lines alike, OCTACHRON includes smart randomization, parameter lock per track, MIDI mapping presets for popular drum apps, and live performance features like instant pattern switching and per-track mute. It offers offline operation, no ads or tracking, and timing options from the host or Ableton Link to fit into your workflow.

## Review summary

OCTACHRON MIDI Drum Sequencer is praised for its ease of use combined with deep sequencing features and strong cross-app MIDI mappings. Reviewers note solid AUv3 integration, good external-hardware workflow, and responsive development. Common drawbacks include pattern-count limitations, occasional stability issues with updates and routing, and several missing features (note length, octave range, MIDI recording, sample import) that some workflows require.

### Pros

- Easy to use but deeply capable, appealing to both beginners and pros.
- Rich MIDI capabilities including built-in app MIDI mappings, CC modulation, randomization, mutation, and presets.
- AUv3 compatibility and strong cross-app workflow with multiple apps and layouts.
- Excellent support for external hardware and as a hub to drive other apps/devices.
- Active development and engaged developer community with frequent updates.

### Cons

- Pattern management is limited (reportedly only up to 8 patterns), which can hinder complex projects.
- Stability concerns in some setups, including pattern routing/update issues and occasional glitches when switching patterns or updating the app.
- Missing core features (no note length and only 1 octave, no MIDI recording, no direct sample import) that limit certain workflows.
