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™

About

TRAMBIENT

Read full description

A personal soundtrack for public transport in Manchester by Fritz von Runte TRAMBIENT is an app that plays music synchronised to the Manchester tram. The music is written and produced by Fritz von Runte, local artist, and the stations it currently syncs to are between Manchester and Bury. In 2021, after calling South Manchester his home since the 1990s, Fritz von Runte moved to Bury. But his friends, barber, dry cleaning and favourite record stores didn't move with him, so he has been using the Metrolink a lot. Since then, Fritz has been making ambient music inspired by and for the Manchester Tram — specifically for the Journey from Bury to Manchester and back. This new music isn’t coming out as an album or a record, but as an app. This app will be a companion for the commuter of the green and yellow lines, easing in the journey to the vibrant city of Manchester from the leafy suburb of Bury, and calming down the journey back. The listening experience will always change too as it’s not a ‘static’ record. It isn’t an album either. But a collection of music, changing itself on every play, automatically synched to the stations in the journey. Embark on a soundscape that's always evolving. Our app features a unique algorithm that personalises each journey. As you travel and listen, the app seamlessly mixes the current track with the next, using multiple possible starting points for a fresh listening experience every time. There's potentially 1.7 million versions for Bury to Victoria — and another 1.7m for the journey back!
