Siren: AI Piano App

Meet Siren, the world’s first AI piano app.

Describe any sound you can imagine, and Siren turns it into a brand-new instrument you can play instantly. Create everything from beautiful acoustic pianos and vintage synths to strange, cinematic sounds that have never existed before.

Siren is for the moment when you hear a sound in your head but cannot find it anywhere else.

Start a song with an instrument made specifically for it. Find fresh inspiration when every preset sounds familiar. Create a piano that fits the mood of a film, a synth that feels pulled from another era, or an entirely new sound based on a few words, a feeling, or an idea.

You do not need to be a sound designer. Write what you want, speak it aloud, or tap the microphone and imitate the sound yourself. Siren brings it to life as a playable instrument.

Explore Types like Acoustic Grand and Classic Synth Keys, then shape your creation with Vibes, genres, eras, descriptive ideas, and detailed Controls. Every sound is uniquely created for you—not selected from a preset library.

Use Siren to:

• Discover sounds that make you want to write
• Create the perfect instrument for a song
• Capture musical ideas wherever inspiration strikes
• Turn feelings, images, and concepts into sound
• Hum or imitate an instrument you cannot describe
• Build a personal library unlike anyone else’s

Every instrument you create is saved automatically. Search and filter your library to quickly return to old ideas, unfinished songs, and favorite sounds.

Siren is also available online and as a VST3 and Audio Unit plugin. Your library stays synced across your devices, so you can discover a sound on your phone and continue using it in your studio.

Stop searching through presets. Create the sound you imagined.
