       Show HN: I made a body-interactive music app
        
       I made this iPhone app called "Affine Tuning" which is a collection
       of body-interactive musical pieces: https://affinetuning.com/ It
       uses body tracking (Motion Capture from RealityKit) to shape
       dynamic compositions. The app is completely free and will be
       updated in the future with more songs and other interactive
       features.

       | Bravo! I have waited for something like this for a long time.

       | Back in the early 90's I saw this interesting band called
       | D'Cuckoo at Stanford that used a variety of midi triggers to
       | redefine instruments relative to performed movement.
       | https://en.wikipedia.org/wiki/D%27Cuckoo Now this can be done
       | with AR.
       | 
       | Your implementation is very tight. I can see a lot of potential
       | here. I'd throw money at in app purchases of other setups and
       | even better would be the ability to load in my own samples and
       | customize the associated movements, etc.
       | 
       | Is this a side project or are you planning on monetizing?
       | 
       | Anyone know of other AR music generation tools like this? I tried
       | some searches, but didn't come up with anything.

         | pointer.

         | During my research I found a lot of projects that connect body-
         | movement and interactive music which could usually be put in
         | one of these categories: 1. research projects that never left
         | the university 2. art installations or performances - So both
         | were tied to a specific time and place. My goal was to create
         | something mobile, bringing this kind of experience into the
         | home, or wherever.
         | 
         | Right now this is a non-commercial product, like a test
         | balloon. I can imagine to collaborate with musicians and offer
         | their creations as IAP in the future.
         | 
         | About bringing in your own samples etc.: I have started to work
         | on an editor (native Mac app) with which people could create
         | their own interactive compositions. They could then import them
         | into the app and ideally even share them with others. I hope to
         | have a first version out in a couple of months; luckily I got a
         | tiny bit of funding for that project.

       | A few ideas at random:
       | 
       | - could be neat to have the ability to send OSC (i.e. send the
       | same values that you're using to generate the music i.e. limb
       | position / angle / velocity, etc.) so that computer-based synths,
       | video softwares, Max MSP, etc. could ingest it in real time as
       | well
       | 
       | - it would be fun to have different synth "presets" or "patches"
       | which connect limb movement to different parts of the audio
       | generator -- i.e. connect right arm with LFO rather than the
       | oscillator pitch for instance
       | 
       | - just curious, does it support multiple dancers?
