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 synchronise your heart rate with Ableton Link, providing a seamless connection between physical state and musical output. * Apple AirPods 3/4/Pro/Pro2/Max: Use earbuds or headphones as head tracking controllers and use nods and turns for 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. * Embedded Pure Data (pd) Engine: Advanced users can run their (vanilla) lipbd patches on their device, fully controlled by external data. Includes pd skeleton project. * Ableton Link supported: Sync you activity level, heart rate or driving speed to devices and apps running Link. * Data Recording: For convenient data mapping, first record performances, rehearsals or tests, then play back the data streams and refine synthesis parameters and mappings. Use the .tsv formatted recordings to analyse your data further and play it back for visualization in, for example, TouchDesigner. 
 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. ## Key features - Sensor data mapping to OSC/MIDI - Physical computing with wearables - Apple Watch heart rate sync - Head tracking with AirPods - Geospatial interaction mapping - Embedded miRack and Pure Data engines - Ableton Link support ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/holonist/id1359763686/reviews.md ### 5/5 — Excellent *2025-01-25* Simple connectivity, works great with Ableton and M4L ### 5/5 — Very cool if you like using movement as music! *2024-06-23, version 1.2.6* The integrations are great, having a large range of inputs and sources of data for your music makes it extra fun. They just added Ableton Link support too which adds sooooooo many more ways to use this! I'm excited to see every update for this app. ### 5/5 — Fascinating Midi Modulation *2024-01-18* 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. ### 5/5 — Great tool *2023-10-11* 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. ### 5/5 — Just Download It *2022-11-28* I was hesitant to download because of price. After downloading it no longer felt expensive. This is a quality app, lots of fun and importantly respectful of your privacy. **Developer response:** Many thanks for your review. We have many exciting features coming up for Holonic interactions with the real world in the new year. All the best and good luck! ### 2/5 — Great idea poorly implemented *2022-07-03, version 1.1.2* I expected a lot more from this app. It is not intuitive and overall is poorly designed. I have as unable to get any midi out from the device while the Osc seemed to work well. I bought it in conjunction with Holon which also suffers from similar problems. ### 5/5 — Fall into the Rabbit Hole *2021-04-23* As a previous reviewer has said this is an amazing app that allows you to link internal or external instruments and play them with a bevy of sensors. Works best with mirack and on pachstorage.com there are a host of templates that you can use with mirack. I have just bought a movesense sensor, since I was using this on an ipad and moving the ipad around to make sound is ok but a little cumbersome, I reckon used alone on the iphone it would be ideal. But now with a tiny sensor I can dance and the sensor triggers music. Welcome to the new world of music making as you fall down the Rabbit Hole that Holon.ist creates! ### 5/5 — One of the most interesting music apps around *2020-07-14* This has to be one of the apps with the most potential for creative sonification of data. I have experimenting with this app for some time and I’ve barely scratched the surface. It is amazing and keeps on opening up new possibilities. ### 5/5 — Works as described *2019-09-18* No problems ### 5/5 — Expensive and a bit clunky but worth it *2019-08-17* I was confused at first but for an extra 4.99 I can now control Ableton link bpm with my heart rate from the Apple Watch sensor **Developer response:** Thanks for the review and very happy to hear you use heart rate to BPM with Apple Watch, it's such a fun feature. We promise clunkiness will be removed in future versions. ## Frequently asked questions about Holon.ist ### What is Holon.ist used for?
