Conditions Weather Synth

A weather-driven synthesizer that turns live conditions into playable soundscapes with touch keys and external MIDI.

Conditions is a weather-driven synthesizer that transforms live atmospheric data into playable sound. Search for any city and Conditions maps temperature, humidity, barometric pressure, visibility, wind, time of day, and precipitation into evolving synthesis, sample selection, and effects.

Built for immediate play, Conditions works with the on-screen keyboard or an external MIDI controller for performance. The app also caches weather data so it can reopen into a playable state even when you are offline.

Whether you are sketching, performing, or exploring new textures, Conditions gives you a living instrument shaped by the atmosphere around the world.
