Respiro Wind-Synth for iOS is a free standalone app (IAA) and AUv3 plugin synthesizer giving you access to six fully functional wind instruments for your device. The app may look simple, but under the hood it has the full Respiro physical modeling engine.

When combined with the paid desktop (Mac/Windows) version of Respiro, it allows you to transfer all of your favorite Respiro instruments from your computer to use them for performance or production on your iOS device.

Respiro is a unique software synthesizer using a state-of-the-art physical modeling sound engine. Respiro reproduces the expressive and sonic qualities of woodwind instruments. It transforms your breath into amazing interactive musical vibrations!
