What's New in Holon.ist

1.2.9

April 18, 2025

It's time to say goodbye to Bose AR. This feature was already deprecated when Bose sold the patent to Amazon in 2020. The latest version of Swift does not support this framework anymore. Thanks for showing us the future of musical spatial computing. Some other dependencies have been updated to the latest version. We also removed Mac and Apple Vision Pro support until we can get them to work properly. Factory presets will be updated in the next version so bear with us!

User reviews

Excellent

Simple connectivity, works great with Ableton and M4L

Very cool if you like using movement as music!

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.

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.

Just Download It

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.

Response from developer

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!
