Your AI Co-Producer

Plain-language prompts — describe beats, chord progressions, melodies, or full arrangements

Multi-turn refinement — the AI remembers the session so follow-up edits stay coherent

Compose in layers — ask for "a horns section" or "an ostinato under the piano" and the new named, instrument-tagged layer lands alongside what you already have, never replacing it

16 genre modules — each with its own creative philosophy; keyword-weighted detection picks the right one automatically

Pro Mode — optional two-pass generation: Stage 1 plans the arrangement, Stage 2 generates MIDI matching that plan. Falls back to single-pass automatically if planning fails.

Batch generation — explore 2–5 variations from one prompt. Pick the keeper, save the rest to the library.

9 AI providers, every model list fetched live — BYOK for cloud, zero keys for Ollama + LM Studio

Structured output where the API supports it; a resilient parser auto-repairs the rest

Dual-mode piano roll — Ableton-horizontal or Synthesia-vertical, one-click toggle

Chord detection overlay — 28 templates with inversions, slash notation, extended chords through 13ths

Built-in piano playback — the Headroom Piano through the sfizz SFZ engine; hear results instantly with no audio plugin on the track

Raw / Clean / Enhance pipeline — Raw is the AI's untouched output, Clean applies safety fixes only, and Enhance layers in quantization, humanization, velocity shaping, and optional dissonance correction. Hot-swap modes mid-playback for instant A/B.

Layers view — a dedicated panel lists every layer with its instrument, a mini piano-roll preview, and per-layer Solo / Mute, plus the clip's detected key, tempo, and layer count

Per-layer colors — every layer gets its own color in the piano roll so overlapping parts stay readable

BPM override — change tempo post-generation without re-generating

Auto-save — every generation stored as .mid with full metadata (key, scale, BPM, prompt)

Versioned, not scattered: refining a generation in a chat adds a new version to the same entry instead of a new clip, so one idea stays together. Expand any entry to browse its version history and reload an earlier take.

Stars, favorites, tags, search — organize the way you work

Per-clip actions — Preview, Load, Send to Chat, Generate Variation, Reveal in Finder, Delete, inline rename

Live MIDI capture — record from a controller or DAW routing with auto-analysis (key, chord, texture, density, rhythm). Send captured clips straight into the chat as context.

Drag-to-DAW — drop the rendered MIDI directly into Ableton Live, Logic Pro, FL Studio, Pro Tools, Cubase, Reaper, Studio One, Bitwig, and more

Named multi-track export — every layer exports as its own named track with the matching General MIDI program; drag the whole arrangement or a single layer

Lock to Host — sync BPM and time signature from the DAW in real time

Custom system prompts — teach Aether your house sound; appended to the built-in engine, never overrides safety rules

10-level undo/redo with full state restoration — Cmd+Z / Cmd+Shift+Z

Per-provider temperature — pin a fixed creativity value for any provider to dial in consistent behavior
