Pro Mode & Batch Generation
Pro Mode plans your arrangement before generating for tighter structure; batch generation produces 2–5 variations from one prompt.
Advanced Generation
Pro Mode
Pro Mode is a two-stage generation pass. When enabled, Aether first asks the AI to plan your arrangement — structure, section lengths, layer assignments — then runs a second call that generates MIDI matching that plan.
Two passes produce noticeably tighter form for complex prompts: multi-section arrangements (verse/chorus/bridge), longer clips, and prompts where the arrangement structure matters as much as the notes.
How to enable
Click the Pro Mode toggle on the provider badge at the top of the chat panel. The toggle persists across sessions.
Graceful fallback
If the planning stage fails (network error, invalid response), Aether automatically falls back to standard single-pass generation without interrupting your workflow. You'll still get a result.
API usage
Pro Mode makes two API calls per generation instead of one, so it uses more of your provider quota. Disable it for quick sketches; enable it when structure matters.
Advanced Generation
Batch Generation
Batch generation produces two to five variations from a single prompt, each generated sequentially with slightly different sampling. Use it to explore options from one idea without re-prompting.
How to use
Toggle batch mode in the chat input bar and choose a variation count (2–5). Send your prompt as usual. Aether generates each variation one after the other with a live progress indicator showing the current variation.
Switching between variations
When the batch completes, a picker appears above the chat showing numbered buttons (1, 2, 3…). Click any variation to load it into the piano roll and transport. The library auto-saves all variations so you can recover any of them later even if you move on.
Cancel mid-batch
Click Cancel in the status bar to stop the batch at any point. Variations that already completed are kept; the rest are skipped.
