ThunderBeast
Summon the weather.
A weather synthesizer. Rain, wind and thunder are synthesized outright — never sampled, never looped — so a downpour can run for an hour without repeating itself. Eight city climate presets move the scenery, the weather and the colour of the whole interface in one move, and every strike is drawn on screen as it happens. Play it from a keyboard: notes from C2 up make the rain ring at the pitch you play, and notes below C2 call down lightning.

“Summon the weather.”
ThunderBeast is a synthesizer whose instrument is the weather. Rain, wind and thunder are built from scratch by the engine rather than played back from recordings, so nothing loops and nothing repeats — leave a storm running and it keeps inventing itself. Eight city climate presets change everything at once: the scenery, the weather over it, and the colour of the interface around it. Move Precipitation and Drop Size for the rain, Wind Speed, Gust and Turbulence for the air, Storm Rate, Storm Energy and Cell Distance for the sky. It is playable. Notes from C2 upward make the rain ring at the pitch you play, so a downpour becomes a tuned instrument you can write parts for. Notes below C2 summon lightning — and each strike is drawn on screen the moment it lands. The standalone app has REC built in, so a take can be captured without opening a DAW. Third in the Beast family, after NoizyBeast and TurboBeast.

USE CASE
Lay a city under a track and let it rain for as long as you need — because nothing is looped, long passages never give themselves away. Build a transition by opening Precipitation and Storm Rate together, then pull Cell Distance in until the strike lands on the downbeat. Or play it: write rain as MIDI from C2 up and it rings in key with the track, and drop notes below C2 wherever you want lightning.
FOR
Producers who want atmosphere that behaves like weather instead of a loop, sound designers who need storms on demand without a field recorder, and anyone who works better with rain in the room.
