Holon is an auditive mixed reality app that generates synth music from your body movements and the world around you - your behaviour. Use functional feedback for active commuting - or almost any sport you can think of - Holon adapts seamlessly to your activity and context.

Holon couples movement with sound in an immersive, physical experience that supports and encourages movement in different ways. Optional hardware supported by Holon includes Apple Watch and Suunto Movesense smart sensors. In addition to Apple AirPods Pro, Holon also supports Bose AR equipped headphones for fully immersive musical experiences.

Your fluctuating heart rate (using optional Apple Watch S3/4/5/6, IAP available) and step rate changes the tempo of the music, while other musical content is generated in real time from your activity, course, weather, time of day, health data and many other signals. Try Holon in an elevator or on a train for speed-controlled tempo!

Holon is based on principles of affective design and biomusicology and puts the user in the centre of an open world of synthesised sound.

“This was crazy fun to play with... jog around, and music responds. It’s like having a generative composer following you around, writing music for your workout”, Peter Kirn, CDM

“It's hard not to crack a smile when Holon starts creating music to match a person's movements. There's something entertaining, almost mesmerising, when seeing how a synth interprets human movement and attempts to make music, not just sound, from it”, Rounikh Zeti, Ask Audio

“Holon is a genuinely innovative music generation app ...The app creates music that feels so much in sync to whatever activity you’re doing. Try dancing with it, and you’ll find out that you have a tune that is playing in sync with your dance moves”, Shivam,

Holon features a bonus demo mode of our editor, It automatically sends pre-configured OSC control data over the network, as well as Ableton Link clock derived from activity/speed/heartrate (if available). Try it with VCV Rack, miRack or our plugins for Ableton Live and Reaktor!
