Droneo will bathe your ears with rich polyphonic textures! Droneo is a synthesizer which drones with various timbres and precise intonations that blur the distinction between tones, timbres and chords. Its drone is great for meditation, centering, and calming, walking and biking, but also can be set up for discordant noise and insect-like buzzing and chirping. With Droneo, you can create surprisingly rich, motion filled drones which change over time in a controlled way. Quietly nested in your earbuds or blasted though your stack of amps, Droneo fills your droning needs! Droneo is a relative of one of my other iPhone Apps, SrutiBox. Droneo works with Audiobus and IAA to expand its droning capabilities. —————————————————————————————— Best app I have! "Absolutely love this beautiful app that I use every day. Fantastic concept. Ingeniously implemented. Worth buying an iPhone for!!" -- Petey Pete UK ''Brilliant ! Haunting & beautiful. Inspiring to use in creative music projects for recording or even live performance. The aching, melancholy voice drones are a perfect, gentle way to relax, meditate, induce calm & even aid sleep. Henry you have put something wonderful into the world here, not only an engrossing fun app. Any musicians lucky enough to discover Droneo will find it as cool as I do. Could be used on a daily basis by those practicing relaxation techniques & is a steal at the price!" -- JC / ENGLAND' "Composers delight" This is a truly beautiful little app, and should not be missed by any musicians or dabblers into minimalist or drone based composition. It produces a wide variety of mesmerising drone based tones, all customisable by the user. I have been exporting the audio straight into Logic via a midi keyboard and the results are fantastic. The creative possibilities presented by the iPhone continue to astound me! I highly recommend this app. -- Australian App Store comment Droneo is great whether you use it recreationally to relax or meditate, as a utility either to help tune, educationally to better understand harmonic interaction, or creatively with other music equipment. With a little creativity and effects :) you can use it with almost any type of music. For me, it's had a lasting appeal way beyond most other apps in this price range.[...] Recommended. -- J onah, US Store The most forward thinking music app I have seen. This app allows me to deal with ratios in sound. Most other music apps are limited to equal temperament. Thank you Mr. Lowengard for taking a step forward in musical thinking, and giving us the chance to experience music in a new way via your app, Droneo! -- by mike uhler Wonderful software. With the evolving voices it's as though I'm being accompanied by a living breathing entity - at the same time combined with precise control over what's played: the tuning, the notes and harmonics. -- materialworlds The settings for all the intervals can be visualized and manipulated using a special "Tone Spiral" interface. Droneo is also an excellent way to play with the way chords fuse into timbres. You can get a feel for how certain timbres fit "naturally" in certain frequency ranges, and how tunings and timbres and chords intertwine. Want to know more?

ExoSphere is a creative tool for shaping continuous ambient and meditative compositions, based on five independent sound layers that merge into a seamless atmosphere. It provides an effortless way to create a foundation for ambient tracks or even a complete background piece with minimal adjustments. Designed with slow rhythmic structures in mind, it is especially suited for meditative music and calm soundscapes. At the heart of ExoSphere are five complementary sound elements, each contributing a distinct dimension to the evolving sonic environment: Core - Deep, evolving drones that anchor the listener with resonant low frequencies, creating a grounding presence in the body. Flow - A layer reminiscent of an instrument, voice, or choir that forms the harmonic foundation of the composition. Gentle shifts its color and pitch, creating a subtle drifting detune that feels fluid and alive. Grain - Layers of stretched environmental fragments - whispers of wind, water, and space - that envelop the listener in a textured, atmospheric sense of place. Shard – Fleeting melodic fragments that surface and dissolve unpredictably, like echoes of imagined songs, sparking shifting associations and evoking transient images. Glow - High, sparkling tones that flicker like light on water, bringing brightness, clarity, and a gentle radiance to the soundscape. Together, these layers interweave into a living, breathing composition that never feels static. The result is a continuously shifting atmosphere - equally suitable as a meditative backdrop, a creative foundation for ambient production, or a complete standalone piece. Each layer in ExoSphere is sample-based, giving the user complete freedom to define the sonic palette. You can load your own samples into any of the five layers, tailoring the sound to your personal style and creating highly individual, versatile compositions. For a quick start, ExoSphere also includes a built‑in library of curated samples, offering ready‑to‑use material that can instantly generate immersive atmospheres. ExoSphere offers an easy start with a minimal interface: choose a factory preset and quickly refresh it by replacing samples, adjusting presence and tone. You can create new variations with the advanced randomizer, while detailed panels provide full control for those who want deeper customization. ExoSphere is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). ExoSphere works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, ExoSphere can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. ExoSphere has a built-in detailed description of all parameters also available as PDF file on the application site.
