Projects
Connect your instruments & OBS
Download and unzip the MIDI bridge, then run the launcher for your operating system. It listens on this computer and can serve several instrument inputs and OBS layers at once.
In each project, assign an instrument and choose its MIDI device. Export OBS HTML, then in OBS add a Browser Source, select Local file, and choose the exported file. Stack your Spatial and Reacts sources however you like.
Projects and instruments are saved in this browser on this site. Export editable project bundles for backups or moving to another browser. OBS HTML is a player, not an editable backup.
Open local bridge settings ↗ · For a hosted editor, add its exact site address to the bridge’s allowed websites.
