About this 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.

Ratings and reviews

Really cool, needs a lot of tweaking definitely not a finished product, has potential. The sounds it generates are meh, aside from that if you try to add any effects like delay or anything that manipulates the waveform over time (pretty much everything) the tempo changes with the note because the Ai only generates one note then slows it down or speeds it up as you go up and down the keyboard. This is chaotically bad. 4 stars because there are NO ADS and no token costs! That's awesome!

i have no idea how this is a 4+ app. i love the idea, was really excited, but the resulting sounds are meh. It often gives me almost the opposite of what i specify; "very low attack" had very high attack, etc. It is still pretty cool but it doesn't deserve 4 stars. Besides, the app overall both looks and feels incomplete; ie, not ready for public distro. if it would at least have tuner knobs or allow to adjust the timbre with another text prompt, it would be close to awesome. But as it is? Meh..

Please include record. And keep working on this! Keyboard speed. Then some tweaks available to given sound, start sharpness and sustain etc, sorry I forget the terms since my synths. Only 2 star thing at the moment but I see the huge possibilities. It saves certain stuff you have used. AI creates different sound if you just enter exact same prompt unfortunately, that's AI. Like AI for internet information, basically makes it up! Correctish half the time. But THIS app could be epic.
