Back in late 2018 / early 2019, I created a videopak for the OP-Z. The OP-Z is a lovely little synth / sequencer created by Teenage Engineering that comes with a companion app that talks with it through bluetooth, giving you UI as well as a nifty little feature that lets you upload custom real-time graphics from Unity and have the OP-Z control its content via MIDI. The content you upload to the app is called a videopak.

Under the hood, a videopak is a Unity scene + assets that you export out as an asset bundle that then runs on their iOS app. It can include many asset types (shaders, textures, meshes, materials… etc) and the biggest limiter is no custom C# scripts. To get around some of that custom scripting limitation, it uses the wonderful Klak creative coding library Keijiro made.re.
