Features & Capabilities

Holon transforms your world into a synth. This is not about “soundscapes” or pseudo-scientific productivity hacks. It's the future of music - powered by you, not an AI!

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 synthesise 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.

All of a sudden I feel my phone vibrate with a sound that I could only hear if I put my head up to the phone. I wonder if this could be used in the future to talk to people who do not share a language. If I could describe the sound if I may. It was huuuuum dita dita dita dita dit. Then higher huuuuum...dit dit dit. It was almost like I was listening to a humming person.

I'm impressed-this app lets you interact with the invisible musical ethereal space within which sound itself awaits papered to be drawn out of the world through the interaction of consciousness and action..... Connect to your loved ones and hear the music echoes of themselves, in realtime? whenever you feel too far distanced!!!!! Awesome!!!

Open up you patch and listen to data streams guide the sounds. A wonderful river of auditory 1’s and 0’s awaits. It’s essential to use this with the holon.ist app and well worth the purchase price.
