Droneo is a powerful polyphonic synthesizer designed to create rich and immersive drone textures. Developed by Henry Lowengard, this full version software is available for iPhone users.

With Droneo, users can explore various timbres and precise intonations that blur the lines between tones, timbres, and chords. The synthesizer offers a wide range of possibilities, from calming and meditative drones to discordant noise and insect-like buzzing and chirping. Its motion-filled drones can change over time in a controlled manner, allowing for dynamic and evolving soundscapes.

Droneo is highly versatile and can be used for various purposes. Whether you're looking to relax, meditate, induce calm, or aid sleep, this app provides gentle and aching, melancholic voice drones. It is also a great tool for musicians and composers, offering creative possibilities for recording, live performances, and minimalist or drone-based compositions.

The app has received rave reviews, with users praising its haunting and beautiful tones, its ability to induce relaxation and aid in sleep, and its compatibility with other music equipment. The settings for intervals and chords can be visualized and manipulated using the unique "Tone Spiral" interface, providing precise control over the sound produced.
