Holon makes the city your instrument. It turns your movement in the environment into a synthetic, interactive score that reflects your context, supports your activities and alerts you to changes in the surrounding area. Holon uses physical computing and a geospatial dataset to synthesize music on the iPhone in real time from your data - no streaming or AI involved, just pure DSP and logic. What Holon Does: * Human powered music. Every action generates dynamic, improvised synth music in real time. * Encourages outdoor activities. Holon doesn’t work in your apartment or by shaking your phone around. Move through streets, parks, and transit systems to make the music happen. * Stays out of your way. Zero UI means less screen time, no distractions. * Uses places and spaces to modify the music you make. The environment isn’t background - it’s the score. * The more and further you move, the more things happen in the music. Use your musical agency instead of skipping and swiping. Why Holon Exists: Music has been reduced to a commodity and a background activity for consumerism. Holon isn’t here to help you chill when you swipe, scroll and buy more stuff, or improve your focus when working for the Man. Holon is here to break away from the static, one-way relationship of streaming services and to put the human in the loop - yourself. Forget emoting celebrities with their false sincerity, throw overproduced passive soundscapes and statistical algorithms on the dung heap of history. Holon turns listeners into performers and unlocks the musical potential of places. How to Use: * Go outside - Holon needs space to function, just like you. Different districts, parks, bridges, shops, street furniture - all contribute to the musical output. Strolling around your apartment or shaking your phone won’t do. * Put the phone in your pocket or on your dashboard. * Walk, run, drive - the world is now the interface, space is the machine. * Use the big button in the middle to power Holon off when not in use - Auditory AR can be a battery-intensive process! * Optional Apple AirPods support for head-controlled musical interactions! * Optional Apple Watch support for heart rate-synced music (biofeedback) *the Watch app may take a moment to install* Requirements: * Available in over 1000 regions in more than 100 countries. * Check coverage or request a new area at holonic.systems/holon. * Best experienced with headphones. Ensure adequate battery level for extended use. * A data plan is required to access our geospatial engine but use of data is low. Holon: Become part of the circuit and… Become Sound™

It's broken. Dusty. Hazy. But from those imperfections, something beautiful emerges. Dark Park is a generator of cinematic pads and drones, sounds that feel like they're decaying, collapsing, breathing. It's designed for exploration and instant inspiration. When you enter the park, you're given a navigation device. Tap "Scan", and the world beneath the surface generates a new synth patch. Every result is guided by musical constraints, so even the broken ones remain beautiful. If you find a sound you like, you can save it as a preset. There are two paths through the park. Take the Clear Path for delicate, melancholic textures. Or wander down the Obscured Path, and discover sounds that ache. The interface gives you a curated set of controls: Fog. Halation. Sodium. Spray. Pressure. And of course, the familiar ADSR controls to shape the sound further. Play Dark Park as a standalone instrument, or combine it with your favourite effects to create dark ambient music or arthouse cinematic scores. Feature list: - Cinematic synth engine designed for dark ambient, tension beds, drones, pads and atmospheric scoring. - Instant scene generation for fast discovery of new sounds. - Carefully voiced macro controls for shaping mood, depth, motion and character. - Fog control for darker or clearer overall tone shaping. - Halation and Sodium controls for analogue glow, slow evolution and atmosphere. - Spray and Pressure controls for texture and low-end weight. - Full ADSR envelope control. - Hold mode for sustaining evolving drones hands-free. - Built-in on-screen keyboard with octave shifting. - Scene browser for loading, saving and managing custom scenes (presets). - AUv3 support for use inside iPhone and iPad hosts. - Also compatible with Mac devices and supporting DAWs. - Standalone app for direct play without a host. - Designed to produce inspiring sounds quickly without menu diving. Important Information: • Device Layouts The standalone iPhone version and iPhone AUv3 versions are fully optimised for the iPhone screen. The iPad standalone app, desktop version, and AUv3 plugin use a fixed 1:1 interface layout. • Focused Sound Design Dark Park is intentionally designed with a specific sonic identity: cinematic, dark ambient pads and drones. It is not a general-purpose synthesiser and does not aim to recreate every type of synth sound. • Instrument Philosophy Think of Dark Park as a dedicated hardware instrument or soundbox. It excels within its intended palette rather than covering all synthesis styles. • Effects & Processing Dark Park contains no built-in effects. For best results, especially within ambient genres, use external processing such as reverb and delay.
