"Don’t let audio be an afterthought! Join us for this hands-on lab and learn how to build immersive game experiences in Fortnite by leveraging MIDI and Patchwork.
Unreal Editor for Fortnite (UEFN) supports MIDI through the use of MIDI assets, allowing creators to use MIDI data to drive various audio aspects of their Fortnite islands. Fortnite Patchwork is a suite of devices for Fortnite Creative and UEFN that you can use to create and manipulate music and visuals to sync with your gameplay. In this workshop, learn to utilize imported assets to create modular Fusion Patches and leverage various Patchwork devices.
This session looks at how to engineer your game so that it responds accurately to imported audio files, even enabling players with hearing impairments to anticipate what is coming next. By the end of the session, you’ll have a playable side-scroller game you can take with you."
