Holon.ist lets you create immersive geospatial musical interactions and physical computing experiences by mapping sensor data and real-world signals into OSC and MIDI CC messages.

Holon.ist is also the companion app to Holon. Together, they turn audiences into perfomers and performers into composers.

Key Features:

* Sensor Data Mapping: Use Holon.ist to map data from a range of inputs, including the iPhone’s built-in sensors, supported wearables, and external devices, to OSC and MIDI messages. This makes it possible to create interactive music that responds to your movements and environment.

* Physical Computing: Holon.ist supports physical computing with wearables, enabling the use of real-world signals to control musical parameters with functional feedback. This can be used in performance settings, installations, and other interactive environments.

* Apple Watch Support: Enhanced support for Apple Watch allows you to synchronize your heart rate with Ableton Link, providing a seamless connection between physical state and musical output.

* Apple AirPods 3/Pro/Max: Use earbuds as head tracking controllers and use nods and turns as accompanying musical gestures and modulations.

* Movesense Smart Sensors: Holon.ist supports up to 6 Movesense smart sensors per device, enabling you to incorporate a wide range of biometric and motion data into sonified choreographies.

* Geospatial Interactions: Define geospatial interactions by mapping locations such as Points Of Interest (POI) and Land Use/Land Cover (LULC) data to musical parameters. This feature allows for the creation of interactive scores that evolve as you navigate through different environments. Holonic geospatial interactions are currently enabled in over 1000 global regions. Please see the coverage map at www.holonic.systems/holon

* Embedded miRack Engine: Holon.ist features the same embedded miRack virtual modular system as Holon, allowing you to synthesize sound in miRack and create complex musical interactions based on real-time data in Holon.ist. Holonic patches created in miRack can be shared with anyone that has the free Holon app. Mapping and patch templates are available for Holonic geospatial preset creation.

* Data Recording: For convenient data mapping, first record performances, rehearsals or tests, then play back the data streams and refine synthesis parameters and mappings. 

Holon.ist offers unprecedented control over the musical environment, providing a tool for performers, composers, sound artists, VJs and lighting designers to create interactive, data-driven music experiences.

What’s New

Version 1.2.6

* Improved Apple Watch Support: Sync your heart rate to Ableton Link, providing a real-time connection between your physiological state and your musical performance

* Heart Rate Variability (HRV) from Movesense Sensors: Biometric interactions now include HRV detected from Movesense devices when connected to a supported chest strap. Available from www.movesense.com/shop

* Enhanced Geospatial Dataset: Our updated dataset provides more detailed and varied geospatial interactions, including a wider range of urban elements and expanded coverage areas. Holonic spatial computing features work best in the areas marked red on the coverage map at www.holonic.systems/holon

Fascinating Midi Modulation

This app is by far one of the most creative I’ve ever used. It opens a door to modulating sound by wind, phone sensors, open street map data, and so many more sources. On top of that you have complete control over how to format and scale these values into either midi or OSC messages. It’s brilliant and will certainly make you more engaged and aware of your surroundings. Once you have a collection of data sources selected it’s easy to send them as cc’s to whatever midi app you want. If you are into electronic music it’s something you must own.

Great tool

This app allows all kinds of input from “the real world” to virtual synthesis. I’m sure this can be done other ways but if one wants to just get to it this makes the process quite easy and smooth. It’s brilliant.
