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?

Read full description

Loop-based mangler effect to create slowly changing rhythmic sound structures in deep reverb space from any external sources or samples. Great for experimenting and designing ambient and noise backgrounds with rhythmic elements. The principle of the application is quite simple. It is based on a loop recorder with two loops. When one loop is recorded, the second is played back. When the loop recording stops, there is a smooth transition between them. Three separate outputs can playback the recorded loop with different pitches (speeds), each with its own effects and two automation generators. The mix of these outputs is fed to the convolution reverb. The reverb is packed with a set of long and deep sound spaces that create a blurry and ambient sound. But the main feature of this application is its well designed parameters that make it easy to experiment with a huge number of sound options using any source material from live instruments to synthesized sound. With just two parameters you can add complex rhythmic structures based on Euclidean rhythms, and easy-to-use automation generators with a randomize option to add variations to the sound, allowing you to modify parameters like an LFO or based on a given rhythm. The convolution reverb has advanced options with which you can change and extend the original reverb spaces. Even using the randomization options, in almost every case, you will get interesting and various soundscapes and textures. With these options it is very easy to create the basis for new unique presets. It only takes a little tweaking of some parameters to get impressive results. The loop recorder can be started and stopped manually or by input signal, can use fixed length or overwrite the loop while recording, and has the option for crossfade between the end and the beginning of the loop. All this makes it convenient for live use as well as when processing recorded material. As an extended option, you can use a special mode in which the application works as a direct effect, without the loop recorder. The special mode sampler is designed for quickly load samples and easy control of the application when used it live. This panel contains the input and output controls, essential controls of the loop recorder, and a large area with a recording counter, which is also used to start/stop the recorder. You can assign up to nine samples for fast loading into the loop, as well as save a recorded loop as a sample and to an external file. SpaceFields 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). SpaceFields works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, with supports Audiobus host app. On MacOS, SpaceFields can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option), audio unit parameters and importing samples from any directory on device. SpaceFields has a built-in detailed description of all parameters also available as PDF file on the application site.
