Pro Mode & Batch Generation
Pro Mode plans before it writes, on both the Melodic and Drums tabs, for tighter structure; batch generation produces 2 to 5 variations from one prompt.

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. It is a single setting shared by the Melodic and Drums tabs, so turning it on in either turns it on in both.
Pro Mode on the Drums tab
Pro Mode works on drums as well as melodic, and plans in drum terms rather than arrangement ones. The first call names the subdivision the groove sits on, which pieces carry the pulse and which answer it, where the fills land and what they are made of, how the sections differ, and how the dynamics move between accented and ghosted hits. The second call writes the beat to that plan.
The plan appears in the Thought panel exactly as it does on Melodic, so you can see the decisions behind a beat before you judge the beat itself.
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
Turn on batch mode in the parameter panel and choose a variation count (2 to 5). It starts off every time Aether loads, and starting a new chat turns it off again, so it is always a deliberate choice rather than something left on from last time. Send your prompt as usual. Aether generates each variation one after the other with a live progress indicator showing the current variation. Each one is asked to differ from the ones before it, and creativity is stepped up across the batch, so the last variation explores further than the first.
Switching between variations
A picker appears above the chat showing numbered buttons (1, 2, 3…), and each one lights up as that variation arrives rather than waiting for the whole run. The first variation to land loads straight away, so you can listen to it while the rest are still generating. Click any finished variation to load it into the piano roll or kit lanes and the transport; if you do that mid-batch, Aether leaves you on the one you chose rather than moving you as later ones arrive.
The library auto-saves all variations so you can recover any of them later even if you move on. Undo treats the whole batch as one step: it takes you back to the clip you had before you sent it, not backwards through the variations you already looked at and passed over.
Cancel mid-batch
Click Cancel in the status bar to stop the batch at any point. Cancelling discards the whole batch, including variations that had already finished, and clears the picker. If you want to keep what a batch produced, let it run to the end and then choose from the results.
